I've gotta say the most impressive thing about these videos is how nice the shots are. They're not crappy and out of focus or barely showing where youre at on the car. Good job!

[@MrSubaru1387]

Thank you. Glad you enjoyed the video. 👍

[@B.R.BGarage]

@@MrSubaru1387 would bent pinch welds collapse if used ?

[@chickenfeet8558]

That's the only thing I'm looking for in car videos honestly

[@andresalizaga1]

I've saved over $200 just in my first month of having a Forester, thanks to your videos. There's also peace of mind knowing you did everything properly, unlike some bad workshops.

[@albundy8139]

Great video! One recommendation though, I always put my jackstands on plywood cut twice as large as the jackstand only when working on dirt or gravel, keeps things from shifting unexpectedly.

[@MrSubaru1387]

+Al Bundy hopefully I'll have a nice concrete floored shop with a lift or two again soon.

[@robertf3397]

I do this too. Also good idea of you have a paved (asphalt) driveway. That way your jack stands dont sink down into the asphalt on a hot summer day.

[@kenbender373]

The things u learn on these vids rocks. Thank u

[@carlv1430]

Thank you for not making your video twice as long by making us watch you break nuts and bolts loose. Thank you for not playing loud circus music throughout video. Thank you for not explaining your theory of the universe to me. A rare, well shot, perfect info only post; TY TY

[@Ureyeuh]

Your detail and effort are impressive, and that's why I love this channel. Subaru owes you, because I keep buying Outbacks since I know you've likely got a repair guide for most common issues.

[@morganridings5725]

Concise, to the point, all the needed information, and I have to reiterate what was already said, the clarity of your video shots and angles are second to none. I have been wrenching on all of my vehicles since I could drive. If I would have had more videos to guide me like the ones you make, I would have had A LOT less headaches and would have saved many hours of my life and spared myself many frustrations. The long and short is, we appreciate you my guy. Thanks for sharing your knowledge with us!

[@RexinOridle]

First time in my life I'm seeing a spindle bolt come out that smoothly. What magic is this?

[@morganridings5725]

I thought the same thing when I saw that cross bolt come out! I was like Oh hell no, ain't no way that came out that easily, he already used a breaker bar on it unless... he just abracadabra'd it? LOL Just replaced my rear wheel bearings and it must have taken me a solid 15-20 min either side getting the suspension knuckles off because those bolts just did not want to budge...

[@cs_yt]

You make videos the way I like, no BS, direct to the point and no other waste of time. Thanks! My rear diff just started to whine, I'm a little P.O. cause it is barely outside warranty. I'm now debating if I do like you and get a used one, or tear apart and rebuild it myself.

[@evanyoung7673]

I thank you so much for this video. I realize it is an older video but it has helped me tremendously. I am currently ground up rebuilding a forester with a part out outback and I have never done any of this before. So thank you very much.

[@MrSubaru1387]

You're welcome. Glad to help.

[@10MinutestoRouletteFortune]

Just wanted to say thanks. As I'm a visual/hands on learner, by you not talking actually helped me retain the info better as hearing to a visual learner screws up the right and left side of the brain leading to confusion. Subscribed!!

+Nolan Gunn glad to help!

[@andrewvisiko5250]

Hey MrSubaru1387 good video. This video helped me with some work I was doing to my differential on my 2007 Subaru Legacy. I too had a lot of backlash after watching this video that I was concerned about. My bearing caps on mine were broken around where the 5 M8 bolts go in on a lot of them. So I changed them out with new OEM ones. I did come to the conclusion why the backlash was so excessive. The aluminum bearing caps and the difference between material (aluminum and the cast) steel created corrosion between it and the shims thus increasing the backlash. I cleaned up the shims and all the mating surfaces and replaced the bearing caps, and now it’s a lot better. A little back lash but nothing like it was before. I would say it’s around factory spec of .007.

[@eggpod4567]

Still here, looking at videos from you. You're the reason my cars still going after two years of me owning it. 🤣

[@perro7183]

You make it look so easy I'm tempted to do it myself

[@1064291]

Just bought a 95 impreza swapped with an 03 ej20 going to need help and I'm glad you're here making these videos. Def makes me feel more comfortable with it

+Julian Arra glad you enjoy my videos. Glad I can be of help to you.

[@Norsology]

Thank you. Very informative. You have been dealing with your rear suspension before i guess - getting that long lateral link bolt out that easy. Mine were rustwelded inside the two bushings.

[@MrSubaru1387]

+Norsology nope. Actually the first time removing them. The car is a rust free, southern vehicle. You're very welcome. I'm glad you enjoyed the video.

[@fredastaire6156]

I have a project STi that Im working on currently. The rear diff is leaking from somewhere because the back plate is all caked with dried residue. This video could not have come at a better time!! Thank you for posting. ~Cheers!

[@stephenhunt6253]

2:57 - Oh my, I LOL'd at this so hard: It took you about 2 seconds. Up here in rustland (Canada), each bolt would take over an hour *IF I'M LUCKY* with an impact, air hammer, and about 1 full can of PB blaster (worst case the bolt is so rusted to the knuckle that it breaks off and I have to remove the whole knuckle and drill it out). :-D

Great vid bro ... Have to change out a rear dif on my 2010 just did the trans last week the rear gears were so bad trying to get home it fried the trans ... I have 200k on car n motor but found a trans and rear dif and driveshaft with only 44k on it ..replaced both front axles when did the trans now I will replace the rear too when I do the dif thia weekend ... So EPIC video bro thanks so much for sharing thats exactly what my rear sounds like it what destroyed my trans as well ..light and love n many blessings to you and yours keep up the amazing vids please

[@dasonjacob2181]

Thanks for the video, made the job fairly easy. But... I missed the comment about seating the CV joints into the differential until they engage the C-clip. They'll go in almost all the way, and look good. But when you drive the vehicle, eventually they'll slide out about half an inch, and then that wheel is spinning free. All you notice is that the car suddently acts like the clutch is slipping. Easy to miss this step and difficult to diagnose once it's all together.

[@bluemorpho4941]

I like how this video popped up in my feed as Im just getting ready to replace my rear diff. Just did a transmission swap, turns out the final drive ratio is 4.44 in the new/old trans I installed and my original rear diff is 4.11. Gotta match those suckers…

[@samuraikitty18]

I know this is an old video but I want to say 1) this was well shot, and 2) it's nice to see someone actually working outside on gravel like I have instead of in a wonderful garage. I don't have power tools, though. Good job! Very informative. I wonder how heavey that thing is?

[@kenbender373]

Doing one this week bro man great vid thank u

[@MrSubaru1387]

No problem 👍

[@ranch_enthusiast]

You're doing God's work. Keep it up

[@MrSubaru1387]

Thanks!

[@ghostvehicle1362]

Still, thanks for the video. I pulled a diff from pickapart successfully. For me, I ended up disconnecting both the lower arms going to the bottom of the spindle, but it was way easier to disconnect the inner bolts. I also disconnected the strut from above (much easier to remove) and disconnected the ?sway bar?. I didn't have to remove the wheels (the donor car at p-a-p had the wheels locked).

[@jeremyphillips6229]

Great video, my diffs just blew apart yesterday. Habent got to look at it yet with this weather so not positive yet if it's the front or rear. If it blew out good can I expect damage to the axles too? Also, does unbolting the shock mount our anything involved with the job effect the alignment as i just had 1 done 2 days prior to it breaking.

[@randallrojas5435]

mr. subaru, you rock. your vidoes have given me confidence beyond belief. wish you were closer geographically for future major repair service. have a 2009 tribeca. replacing rear diff - front member. 4 bolts. simple, right? any techniques or procedures regarding this? support rear diff with jack, remove and replace? can't wait for new content. always appreciated!!

[@16mmDJ]

Thanks for the excellent video, as always. Looks like I'll have to be doing this on my '99 impreza. Awesome, awesome tutorials. keep up the great work

[@MrSubaru1387]

+16mmDJ you're welcome. Glad you enjoyed the video. 👍

[@16mmDJ]

For sure! I'm curious - you referenced "excessive backlash" at around 10:20 and I think you mentioned something about it earlier in the video as well. Can you describe what you mean by 'backlash'? My impreza's got the ej22 and 4eat, and at first I thought the slight whiplash and clunk i was getting between 2nd and 3rd was transmission related... but now somebody else has told me it could also be related to the wearing rear diff. (also getting a moaning noise at certain speeds). if you don't mind, do you have any thoughts?

[@MrSubaru1387]

+16mmDJ it's always hard to say, sight unseen, but it could be a possibility. Could also be a wheel bearing or could be transmission related. In reference to the differential, I was referring to the amount of play between the ring gear and pinion.

[@16mmDJ]

Got it! I really appreciate the input. I'll try to report back if I have any success :)

[@MrSubaru1387]

+16mmDJ good luck 👍

[@johnjohnson-xg1jc]

I love your channel.. Keep up the good work..

[@ecovoycanada]

Very well done and demonstrated, thanks! I have a 2013 Crosstrek and my rear differential cover (the part that has the fill and drain plugs) is cracked just underneath the drain plug. Do I need to take off the whole differential to change the cover or can I change it with the differential in place ?

[@MrSubaru1387]

You will need to drop the diff to be able to get the cover off. The cover bolts to the rear crossmember, making it basically impossible to get off while in the vehicle.

[@kanewhitefield560]

Hello, great videos have helped a lot, i was wondering if there should be any movement to wobble the cv cups where they slip into the diff? And would that cause early wheel beating failure due to vibration and such, ,thanks

[@darcygeertsma526]

Fantastic video, keep it up

[@MrSubaru1387]

Thank you. 👍🏻

[@davepeters4955]

Redoing the work someone else did on my clutch a few months ago (it seized up) and it took me a minute to figure out why the drive shaft was being such a PITA to get loose from the rear diff. The previous "mechanic" put the lock washers under the bolt heads instead of the nuts. Undid the whole purpose of the lock washers and the flat spot on the bolt heads. The bolts were all splayed out and the threads were trashed by the time I got it out. SMH - time to order parts...

[@MrSubaru1387]

Ouch.

[@patonbike]

Can this be fixed just with new bearings? Does this have shims to adjust the backlash?

[@Ripkallen]

Great and informative video, thanks! One question; is it hard to pop the CV axles back in? Which technique is best to use for this?

[@jmbt02]

Hey im sure youve already figured this one out, but just in case, the CV will just slide in if you line up the ridges on the cv with the opening

[@Ripkallen]

@@jmbt02 Yea I got it when I was working on it, but thanks anyways!

[@ceegee6261]

I just got a 2005 impreza outback sport and with the help of your videos been servicing it including replacing the diff. It runs good but when driving down the road the tires chirp like if accelerating from a dead stop then after 10 to 15 minutes the awd light starts flashing, just replaced all the tires, I was thinking maybe the axles or an axle are binding but really have no clue, idk if the old diif damaged anything when it failed/ locked up. This is my first subaru so any help would be appreciated. Also would driving it in a tight circle alleviate binding if thats the issue?

[@ihatepurolator]

As always, your videos helped me do my own work on my Subaru. I'm going to attempt to change my rear diff axle seal on my 98 Impreza. Do I need to remove that 5 bolt plate in order to get the seal out? Or I can pry it out with a seal pick tool? Do I have to grease the new seal and just insert?

[@MrSubaru1387]

Seal is removed with a lip seal tool. Apply chassis grease between the oil seal lips, as per the factory service manual.

[@Hebert6760]

[@toddkarschner4293]

one other questionon the 99 rear diff change on my manual, would you happen to know which years will fit? also, awesome videos! i own 4 subaru outbacks and watch your vids quite a bit! thanks for the help and keep up the great help for us diy guys!

[@MrSubaru1387]

+Todd Karschner at the least, the 95-04 diff should be interchangeable. Just make sure you've got three same gear ratio. In 95-99 Outbacks and Legacys you have - auto trans 2.2L = 4.11 2.5L = 4.44 5 speed 2.2L = 3.9 2.5L = 4.11

[@MrSubaru1387]

+Dan D not at the moment. Maybe in the future.

[@rockinscienceguy8305]

AWESOME video MrSubaru! But I have a question. I have a 2005 Subaru Outback 2.5i. In your video and on many others, at the end of the axle that goes into the differential there is a slot for a retainer clip... but no visible clip. Does the clip stay inside the differential? I am having a terrible time trying to get the new passenger side half-axle to snap back into place. I wondering if the retainer clip has fallen off or something and is preventing the axle from going in ??? Reponses from you or others will be welcomed.

[@MrSubaru1387]

There should be a C-clip on the end of the axle that goes into the diff. Sometimes it gets stuck and doesn't come out with the axle. Shine a light inside and see if you can spot it.

[@VideoNOLA]

Fun stuff, thanks!! Now if I could just get the proper battery fitment BCI # for a 2018 Outback 3.6r, which the Interwebs refuse to reveal!

[@DrixHound]

To replace the inner retaining clip ring in the differential, is it best to remove the bolts on the side of the differential where the axle goes into the housing to replace the ring?

[@condensermike]

Thanks for the vid. Do you have any footage of doing a center diff on a manual?

[@MrSubaru1387]

I don't. Sorry.

[@rh2racing]

Great video. My son and I are having an issue with the front mounting plate (the one with the 17 and 14mm nuts). The bolts (studs?) Are spinning. How would you get it out?

[@MrSubaru1387]

Can you send a picture to [e-mail]?

[@johnyonker8448]

Hey Mr. Subaru 1387 you seem like the perfect guy to ask. I have a 2016 Subaru Impreza with 90,000 miles on it. I discovered some oil leak spots at the rear of my car where I parked it. Do you think it could be a leaking axle? I’m trying to figure out exactly what it is so I know what part or parts to order.

Great video on the rear...that's what usually goes r the bearings most times...all of ur videos r rite to the problem ..great work...sir.,.looking forward to see what's next...I have two Subarus like I said o9 Forester n a 2001 LLBean addition...w155,000 on it...

[@pinemeadowproductions]

Thanks for the video. I'm having a hard time putting the half shaft back into the differential all the way. Is there supposed to be a retainer clip on the end of the spindle? If so, wouldn't seem to be a reason for it not being able to go in all the way. Suggestions?

[@MrSubaru1387]

There's a clip on the end of the axle. It may have popped off the axle and be inside the diff. This can prevent the axle from seating in the rear diff fully.

[@pinemeadowproductions]

MrSubaru1387 thanks for your time and prompt reply. Maybe using a magnet or removing the diff cover would be the best thing to figure it out.

[@MrSubaru1387]

You should be able to look into the axle hole to see the c clip. They don't go that deep inside.

[@ashnader8627]

Hello ... I am not a DIY type ... but I was thinking of doing some hiking / camping mountain trips in my 2013 Forester. For the stuff I want to do I think it is more than up to the challenge. I recently had to replace rear brakes (very low mileage at approx 50K Km). I suspect issue is with using ABS system for years on icy roads etc. If I wanted to have a mechanical LSD installed on rear and maybe front is it recommended ? I don’t want to spend $50K on a Tacoma.

[@91ludesit]

I have a a 2001 outback that has an RPM dependent high pitched whine, I replaced the manual trans as it was failing anyway and it didn't go away. Its only there under full throttle from about 4.5k rpm up...

[@fPonias1]

What would you replace if you were to rebuild the broken diff? Just the bearings? What about any of the gears or the pinion?

[@christopherohara9421]

I live in New York with rust is bad I can't get my rear bolts out of my spindles when I change my axles or my rear I just dropped the rear and the axles fall out and then I I put it back together like that never taking apart the spindles

[@crownlandproductions]

Awesome video bro! I am currently installing a Legacy Gt transmission and rear diff. To a Brighton, and this will be a big help and make things much easier than removing a lot bolts that are not necessary. The 20 year old Legacy has almost 500,000 on the current transmission. The vehicle when done will be part Brighton, GT, and Outback - check out my instagram account for most recent images as I build her up for her 20th birthday celebration.... all the best, and over n’ out......

[@crownlandproductions]

I didn’t see a size on the lower spindle bolt.... what would you say it is?

[@MrSubaru1387]

The long longer spindle is a 19mm.

[@crownlandproductions]

MrSubaru1387 - awesome - could you be like Zach King and email me your power drill?

[@sivsug]

How much would it cost to this job?

[@Dustin_the_wind]

I first off want to thank you for your videos, they've aided me considerably in many projects I've done with my 2004 outback H6 a/307,000m, still runs well for what you'd expect from the motor; weeping head gaskets, little bit of timing chain music at idle. My question I want to ask is, how would you go about freeing up the fill and drain plug on the rear diff? I tried on jackstands, with a ½ breaker, and working it minutes on end with a Mac tools air impact with absolute zero movement. I applied PB a good few times, tried to torch warm up around the plugs, nothing. I haven't tried to use a floor jack on a breaker bar, which did work on the rear shock bottom bolts(a jack supporting the shock a little for center made those bolts slide right out), and a axle nut, I'm just afraid of stripping it out, or cooking the gasket and having to pull the whole damn thing out. It's a colorado car, and only surface rust on bare metal a touch, very clean/solid for 19 years old. Thanks for your time, I know you get a lot of time bandit questions, and this one probably being one too.

[@waynoswaynos]

Great vid, thank you. I have a 99 legacy which is perhaps slightly different. I am about to tackle this but the workshop manual I just found wants me to drop the exhaust and then the Diff drops down leaving the Axle Shafts connected to the hubs. Whereas your method here spreads the wheels apart so the Diff can be dropped. I wonder which is quicker? I get the vibe that dropping the exhaust will create leaks or be problematic in other ways. Anyone?

[@fortu1606]

Hello friend, what is the relationship between your front differential and the rear one for which you changed? To have a notion since I have two automatic gearboxes that have the same 37/9 tooth ratio in the front differential but where it varies is in the rear differential since one has the 37/9 ratio and the other has 40/9. one box is from 1996 and the other from 2000.

[@juanpablopardoleon3648]

hello mr subaru, greetings from chile, I have exactly this sound in my 2009 impreza, the mechanical gearbox oil was low, now that the sound has been filled up, it continues, I would like to know from your experience if it will only remain as an acoustic nuisance, or does it mean that they are coming more expensive problems? Can I continue using the vehicle normally for a few more years? Or should I change the differential or box in a mandatory way? greetings from Chile !

[@ironman1518.]

THA NK YOU EXCELLENT VIDEO!! in order to replace the differential bushings, can I leave the rear axles in the differentials and lower the differential with a jack, out of the way to remove the old bushings and install the new ones, please? Thank you!!

[@bretthelke9389]

Any tips if the driveshaft won't spin and I cant get the top 2 12 mm bolts off? Rear differential is toast

[@Bststv]

Thank you!!! Idk what i would do without your channel, i am having a same issue with my 2002 outback H6 vdc but do you think the sound can be heard in the front side of the car with same pinion bearing problem? It seems like the sound comes from right underneath) of the center console

[@MrSubaru1387]

Best bet would be to get the car on a lift (preferably) or on jackstands, have someone drive the car on the stands, then try to pinpoint the noise.

[@Bststv]

MrSubaru1387 Ok so i’ve confirmed the sound that its coming from the rear differential after doing what you said to do, thank you! My question is i have 2002 3.0 H6 VDC will any 2002 outback including 2.5L differential be compatible for replacement for my 2002 H6 vdc? Thank you

[@MrSubaru1387]

As far as I can recall, the VDC had a special Limitied slip differential not offered on the 2.5L models.

[@skymitch89]

The rear differential in my 08 WRX sounded nothing like that. It sounded more like the clicking you hear when going up the first part of a roller coaster. It finally broke when taking off from a stop light.

[@MrSubaru1387]

+skymitch89 ouch..

[@mariomoreno9954]

Mr Subaru, have you ever remove the rear subframe? I am removing the subframe of Outback 00 and the front bolts of subframe are very tight, firstly they turned very easy but later started to become more tight, it seems that there are some dust in the cavity that the nut attached to the bodyframe, there is no rust, the threads are very clean, but I dont know how to access to oil them with wd40 or similar to help remove them, do you have any tip? thanks a lot.

[@MrSubaru1387]

I haven't had to remove a rear subframe. Unfortunately I don't have any tips or tricks on the subject. Just be careful. Definitely don't want to strip out break off a subframe bolt.

[@alexingram7569]

Any chance you have a video or could make one for the front differential? Mine is bad on my 2004 outback

[@palmer00]

My passenger side cv axle popped out on my 2013 outback 3.6R, and my transmission light temperature went on. I heard vibrations, then i put it neutral and pulled over. Suburu dealer said I had to replace the transmission and differential estimated 9k for repair. How could the transmission be damaged so much by the differential?

[@robertf4572]

Does it make sense to try and rebuild the diff or just swap with a used part?

[@alexxx3958]

It is required before you start, you are in the proper Subaru attire as demonstrated in the video (;

[@jeanclaude1916]

i gotta do this soon. my rear end is ticking like crazy

[@ikariku]

Hello, what make of axle shaft do you install in your outback? (I noticed that isn't OEM, I looking for a new one for my 3rd gen legacy)

[@MrSubaru1387]

OE Genuine Subaru remans are all I install. Aftermarket axles either vibrate, are too long, or are too short.

[@anotherdrummer2]

Advice for a stuck/seized drain plug? Seems like its a different socket size and depth rhan the fill plug on my 2011 outback.

[@gurmuk101]

I have a problem with my Forester. A few months bad I had the dealership change my diff oil as it was in for another repair. When I got back the car. There was a noticeable whine coming from the rear and a jerk when releasing off the accelerator. The whine also stops when releasing the accelerator. I swapped out the oil for 75-140 and the jerk feeling stopped by about 75%. I then swapped out for 85-140 and I haven't really felt it since. The whining noise is still there though. Is the diff on the way out? The oils where both changed in front and rear

[@MrSubaru1387]

Yea, seems like it. The diffs are suppose to use 75W-90. 75-140 and 85-140 is pretty thick.

Yeah I'm going to change it back out this week. Last week I put in the 85-140. Gas consumption went to the dogs with that. Would all those symptoms be the rear diff? Or the drive shaft also?

[@MrSubaru1387]

I'd check the propshaft, but with noise going away with thicker gear oil, I'd say it's most likely the rear diff.

[@gurmuk101]

Thanks for the speedy response. Well it didn't completely go away but yea the jerk did ease up a lot!

Hello. Symptom on a 2005 manual Forester. Wheel slippage/AWD shudders in tight corners near full lock. I think it is the Torque Bind in centre diff that may need replaced? It's called viscious coupler in USA. Do you need to remove the rear cross member to replace centre diff? Or can it be left in place?

[@josht6918]

My diff whines but the diff support bushes caught fire haha

[@patstonmarcus]

How different would the removal for my 05 Impreza RS diff be? Pretty sure its still the male axels and a 3.90 final gear.

[@juliosdiy3206]

I was wandering if the 2000 to 2004 outback rear diff. gear ratio is the same for auto and manuel? I looked at the model number on the top and its the same.

[@MrSubaru1387]

No. Auto and manual have different gear ratios.

mrsubaru1387, do you speak all those languages or use a translator? I learn alot from ur vids and enjoy the work you do. I want to work for a subaru dealership, any tips?

[@MrSubaru1387]

+Nick Matula all the languages? I'm confused. Glad you enjoy my videos. Tips for getting hired at Subaru... Hmmmm... Have you been through trade school? Gotten your certificates or a degree in automotive technologies? Always a help.

[@nickmatula7622]

MrSubaru1387 my fault for the confusion, i ment when you respond to people in the comments section in Spanish and what looks to me like Russian. I am starting classes this fall at my community college that offers an AA in Automotive Technology. They do not provide ASE testing or certs but my goal is to work on obtaining 3 by the time I earn the AA. Thanks

[@MrSubaru1387]

+Nick Matula sounds like you are off to a good start. You can't get ASE certified in school. ASE does its own testing. You also have to have two years of work experience before you can test to be certified. Two years of tech school counts as one year of work experience though. Just make sure your school is NATEF certified. Big plus. I took 4 years of Spanish in school and work with Hispanic people for 11 years at my first job, got decent with it. The Russian is Google translate. Lol

[@sasukekiller420]

Would the rear differential replacement be the same on a 06 Subaru STI? Also on the torque of the bolts?

[@MrSubaru1387]

+sasukekiller420 yes, should be the same. Not 100% on torque spec similarities. There will be a temp sensor in the rear cover of the STi not shown on this diff.

[@HateCrewReaper]

Glad I found your channel, you seem to know what you're doing, so I'll ask a question I hope you can help with ! I have an AT 2007 impreza, I am experiencing a strong rumble when turning at low speeds in both directions. I read quite a bit about it and many people are calling this torque binding, I heard about putting in the FWD fuse to test it, I did, and the rumble is completely gone. Some say this may be caused by a malfunctioning transfer clutch solenoid... It looks to be a pretty laborious process to change this part. Is there any way to completely confirm, without a doubt, that this is it, or something to do to point the problem to elsewhere?

[@MrSubaru1387]

Rumble from the rear I assume?

[@HateCrewReaper]

Yes from the rear, like I said, with the FWD fuse in, the car runs very smoothly.

[@MrSubaru1387]

Sounds to me like it could be wear in the rear differential. With the FWD fuse in, you're taking power away from the propeller shaft, rear diff, and rear axles. That's where I'd look first. Have you gotten under the vehicle to do a visual inspection? Checked the prop shaft, pinion, axles etc for any movement or play?

[@HateCrewReaper]

Visually, everything looks good. I do feel like the backlash between the prop shaft and the rear diff might be excessive, but then again I have no clue how much backlash is normal on this thing. But wouldn't I feel or hear something odd coming from the diff while even going in a straight line if there was wear in the diff ?

[@MrSubaru1387]

Not necessarily. That said it could be making noise all the time, you just aren't hearing it until you corner, making it worse. This is all theoretical since I can't see the car in person. Just trying to brainstorm. The best thing to do would be to drive it while on a lift or jack stands to see where the sound is coming from.

[@warzee123]

I just figured out my 04 forester was in fwd mode and no fwd light was lit on the dash. I took out the fuse and as soon as i pulled away could I could feel resistance and hear clunking in the rear. I think I need a new or used rear? I don't think there rebuildable? Any suggestions?

[@Jonesy-dv3bj]

Very helpful video! Where did you put the jack when you lifted the front and rear end?

[@MrSubaru1387]

Front, under the center of the front crossmember. Rear, under the center of the rear differential.

[@Jonesy-dv3bj]

Cool beans. I didn't think you could lift from the diff. Good to know. Thank you!

[@PNdebt-hc2tg]

15 Impreza 102k miles. I have rear noise at speeds. Not a wheel bearing or bad tire. Sounds just like a wheel bearing. I have side to side play on the axels where they go into the rear differential. Both sides have side play. Is that normal? Main pinion bearing seems solid, no play. Thoughts? Thank you.
