Ford Mustang Rear End Rebuild & Watts Link - Mullet Mustang - EP07

[@SouthPlanObservation]

I still don't get why you guys haven't got a million subs. Your content is so awesome. At least you're almost at 100k. Keep it up.

[@ScottMerrihew]

SouthPlanObservation with the right video their sub numbers are going to blow up.

[@Fi1del]

oh my good god please do a video on the impreza in the background at 13:05 she looks like a beast! loving the mustang build ! warm hugs all the way from Chile !

[@okhotrodder]

I use to run a speed shop. Shut it down yrs ago to do private repairs. A guy off street outlaws brought his car to me to get his axle rebuilt. According to him, it was the quickest axle repair he had ever seen and also the quietest his rear end has ever been. Told me he was def coming back. He called me a few weeks later, told me he was sorry, but his sponsors didn't want a no name private shop fixing anything on the car. We both laughed, haven't seen him sense. Funny though, a good friend of mine that builds transmissions can tell someone about me, and all the sudden my phone is blowing up from multiple people wanting good, honest work done. Keep up the good work, and honest doings.

[@norevlimitr1602]

Take the old pinion bearing and slightly grind the I/D so it slips on / off the pinion gear easily. Use that to set up the shim thickness and once you have the correct shim then press the new bearing on and do final install.

[@akooner09]

very wise sir, very wise

[@BrookieCooki84]

That’s assuming the new bearings are exactly the same. You’re better off getting two of the bearings you plan to use on final install and doing that to one of them for setting the pinion depth. Swap it out for the new one press fir, and you’re good to go.

[@jakobhurlin461]

Nice work Pete and Dave. You guys sure made life hard for your self-doing all that work under the car instead of just pulling the axle out from under the car and working on a bench.. Since you have all new suspension components.. Pro tip time! If your ever in a rear diff again.. and it’s a shim style pinion gear ( like you have) and not a crush sleeve, take the old pinion bearing your pressed off take the die grinder to the inside of it and take off some material, just enough so it slides back on the shaft… (yes the shaft) of the pinion then it becomes a test bearing and you can slide it off easy so you can get the right back lash and proper amount of shims and it not be a royal pain of pressing bearings once you get the shims right you can press on the new bearing . Keep doing what you guys do! And I’ll see you guys at gridlife 2017 back here in MI. -Jake

[@adamryanclark]

I worked with a guy at ford who had a electric small size deep fryer but he kept transmission fluid in it and he would take and drop his pinion bearing into that and let it heat up to 250* then install it on the pinion without having to press it

[@speedacademydave]

clever idea!

[@Leofred2000]

Cuz Fords cant handle pressure ;-P

[@ryanrohauer5940]

must do alot of rear ends!

[@Stigs722]

How come this channel doesn't have more subs? It's easily the best car channel on KZbin

[@BlakesGarage]

Excited to see the track day. I wonder how much time all of this will shave off.

[@williamsplace01]

i think approximately one beards worth

[@MendicantBias1]

Speed Academy: Full of Great Ideas! Nice video guys!

[@DustysLP]

Can wait to see the finished product and the track day

[@trtlepwr]

please say you put locktite on the ring gear bolts

[@Cubansoilder96]

Eric the car guy can tell ya the pains of doing the shimming of diffs 😆

[@CSkwirl]

Cubansoilder96 yeah he spent 2 weeks doing this same job about 20 times right?

[@PawanKumar-nx1eu]

that is one big black shaft...

[@norcoca]

Please make sure that you get a good contact pattern on the ring gear from the pinion, speaking from experience.

[@subarumoses]

hahaha the catchers mitt joke got me DP!

[@gabebeaucage5141]

You guys are the best e tuners I wish I could be like you 😅

[@NvautoCa]

On this episode of Speed Academy we watch Riley Sexsmith sharpen pencils!! 😂

[@wolfy9005]

1st! to say I was going to go to bed but this vid popped up

[@CarminesRCTipsandTricks]

*The Pinion Depth is OFF, the Contact area is near the EDGE of the Ring Gear* ....... AND THAT'S OK!!!??? YOU'LL "LIVE WITH IT"??? - NOT even getting started on you smacking the Carrier into the Housing WITH A METAL HAMMER.... OMFG! I would have been Fired TWICE for that half ass work!! Hope you're not planning on keeping this Car very long.....

[@Mike.Maliky]

I was a subscriber since 25 subs

[@rogerramjet5092]

Vary curious to see what affect the watts has on lap times. Theory says better with the free articulation. But the proof is on the track. thanks for finally setting the record straight...

[@speedacademy]

Track test episode is coming soon!

[@tim83h]

Initially I was so happy for u guys to be able to work on a hoist but then thought... it would have been funnier to watch PT struggle on the floor 😂

[@samclarke653]

Hey guys. Really don't understand how you guys aren't more popular then you already are. Would you consider further upgrading the exhaust by having a dual exit valve controlled system? Side exits without cats or mufflers and rear exit with. It would a cool power comparison and the side exits would be so fantastically obnoxious.

[@BADD400]

What no new axles?

[@BornMini]

that gc8 in the back of the shop!! I wanna see it!!

[@Toledoa0909]

Hey guys when cleaning a gasket surface don't use a sanding disk you a wire wheels. I have seen people use sanding disk and then the cars come back with a leak cause you took too much metal off one side causing an uneven mating surface therefore you do not get a proper seal.

[@speedacademy]

That is not a sanding disk but an aluminum scuff disk that takes the silicone off and doesn't harm the metal.

[@Toledoa0909]

Speed Academy ohh okay just making sure! See you guys are pros

[@Rudizel]

I got a 13gt that makes a constant noise from the rear axel. The noise sounds like when you first drive your car after its been siting for a long time and the rotors have gotten a bit rusty so as soon as you drive you hear them scraping of the rust. This is the noise it makes constantly. I have taken it to many ford dealerships and have had their top guys look at it with stethoscopes and whatnot. They say the noise comes from the right side of the axel but they don't know why its doing it. When they opened op the rear dif to check the fluid they said the fluid is clean no shavings of metal at all. The car is still covered under powertrain warranty. The car also has a lot of suspension mods so the dealer said this might be a noise that's always there but you are noticing it now due to the stiff links and bushings. Did some research online and a lot of ppl are reporting this noise. Any thoughts?

[@riskyricky22]

Why take shortcuts on the diff install guys?? Make some test bearings that dont need to be pressed on/off to get shims dialed in. Suspension will not matter if you can't get the power down.

[@rogerramjet5092]

The only real worry is noise. They might whine/whur. Have a buddy who didn't get it quite right but kind of sounded like blower so we put up on a lift just check how off the pattern was. decided to leave it 25k later still holding up fine. It's a manual car running drag radials. not a monster but 13.0s all day long. Jimmy real likes that almost blower sound,even coming from the back.

[@adamryanclark]

I've actually had better luck putting the Pinion bearing inside a toaster style countertop oven and heat it up and put the pinion gear in the freezer once both are were I like them temp wise they just drop right together

[@jbalsys82795]

Did that rear end ever make noise

[@jfv65]

compared to the Panhard setup the Watts setup makes the rear of the car feel and behave the SAME in L and R corners. with the Panhard setup L and R corners feel different when the car is driven on the limit of grip.

[@aaaargl]

jfv65 so thats why nascars are using a panhard setup? Emphasis on going left?

[@lb9gta307]

aaaargl they use it in nascar simply because it's a spec series. It's the same reason they still use carburators.

[@jfv65]

aaaargl you will see lots of watts setups on classic RWD rally cars like Ford Escort mk1 and mk2, Opel Manta and Ascona, Volvo 240

[@waclosh]

this is soooo good

[@crossandshoot796]

IRS in the future??

[@jimboi7616]

Hey DP, do you still hang with the Sean, guy who owns Project Leroy, the midori green ek hatch? I saw a picture of you with him and his car on superstreet or speedhunters

[@tomahoks]

wow! A lift! You'd be better off crawling on the cold floor...lol.

[@Joe11Blue]

Should have gone with the Cortex Watts unit...

[@paultavres9830]

Expect blown spider/side gears Seen that type diff in the spicer traclock You need a split carrier with 4 spiders which reduces the torque load Good luck

[@TheZohanLohan]

next time with the pinion shimming try making a 'dummy bearing' by slightly enlarging the old bearing so it can just slide on and off of the pinion. that way you can recheck the mesh without pressing the bearing on and off.

[@rramos7488]

Nice build guys. I recently installed a tomei clutch type 1.5 LSD on my g35. Never drove a car with a clutch LSD and the clunking from the clutch engagement at low speed tight corners is horrible! Let us know how good that friction mod works (what friction mod was it?)

[@banksray9105]

Where do you get the part?

[@konglor9029]

show a video on that subaru

[@jim6267]

this mustang is pretty lucky!

[@andrethornton7846]

I have a 2008 gt mustang it has a s-spring the gears can i drive it without the s-spring like the previous mustangs

[@Fan119]

You should look up a video just google Xtreme Off-Road DIY Axle Setup and they go through the whole shimming process. Its a really good video.

[@alfredolozano695]

Friction modifier smells like what I would think Darth Vaders helmet smells like on the inside... lol

[@klausschaeffer365]

Please show that widebody Impreza!

[@griffsrearmountturbothemod1623]

what a pain too swap out bearings. nine inch is so much easier. nice vid .

[@Mickey-im3bg]

Hey bro I'm sorry about your shaft but there's pros and cons for not ever holding one that big. LOL JK Love your video, good job fellas.

[@TylerBerryFilms]

Sucks that you need to throw over a thousand bucks at the rear end to get it to not hit crowds of people.

[@c-shepard]

You guys should have known going forward what was involved in setting the pinion clearance before taking it apart endless times and dropping it on the floor, unreal.

[@jvrfzr290]

buen video

[@DayoftheJakeL]

lol at beard dude @10:14

[@ethownzbh]

10:10 lol

[@mondomoleno.3404]

The look on his face is priceless!

[@Ellwood76]

"its so greasy....here we go....ooooo yeahhhh"

[@EB240]

yeeewwwwwwww, yea boiiiiiiiiiz

[@DoRC]

Wow that was a really crappy job setting up that diff. The pinion need to be torqued very specifically and the contact pattern on the ring is terrible. You be very lucky if you don't have an extremely noisy diff or worse:(

[@DoRC]

also the backlash measurement was done at the wrong place. It needs to be done at the outside of the ring. where you measured it's going to seem tighter than it actually is.

[@marcosaruca5283]

when is mighty car mods and speed academy gonna do a video together

[@neofitou]

lol. some time after the roadkill one I presume.

[@archiguitarchi]

I need help from you two! I have a 2006 GT that two mechanics have worked on to solve a whining differential. The first had the car two weeks, charged over $300 in time and did nothing. The second has also had the car two weeks, put in all new gears, and the thing still whines under load. He said they set it up dozens of times and can't seem to find the issue. I believe he is honest and I want to help him. Is there any way I could get you on the phone with him? I've invested almost $1,200 and I'm at my wits end, and I know he is too. Is it normal for a GT rear end to whine? I'm not talking about a subtle whine. It is loud.

[@neofitou]

respect lost by not setting up the pinion depth.. :-(

[@lb9gta307]

anyone else wonder, for a second, when they installed the Supertrap? The end of the driveshaft looks the same as a Supertrap muffler lol

[@JBWHITEGT]

I did 410s on my 08 mustang GT and I regret that I ever did them.

[@robertswift6101]

why is that?

[@thordehr]

Walk along, nothing to see here. Do NOT use this as an example of how to set up a differential.

[@Wrenchlife604]

Rip rear end

[@MrDannyd9]

I knew that was gonna happen as soon as you pressed the bearing on the pinion... You guys aren't hacks, don't act like it.(disappointed face)

[@BroadcastBuddy]

Pinion waaaaaayyyy too deep. These are face hobbed gears. Remove pinion shim to move drive contact pattern toward toe.

[@PawanKumar-nx1eu]

cost?

[@vongdong10]

Parts are probably a couple thousand.

[@ryanrohauer5940]

2 fluids every mechanic hates diff fluid and brake fluid.

[@cobrabuilder9336]

Agreed, but Brake fluid cleans up easily with water, Gear oil and friction modifier will stay with you FOREVER!

[@SilverStackers]

and ppl wonder why it cost $500 labor to rebuild a diff. it's a meticulous job that requires a lot of effort to get right.

As a retired Ford mechanic I would give you guys some tips on how to do the rear end but you've already shown me that you just take a hammer to staff so you shouldn't be around a car

[@IceSilvia]

Were's part 2? Don't leave us hanging guys

[@MyLonewolf25]

AWWWWWW YEA! 4LINK Imho Imho I would have gotten a c-clip eliminator kit Don't want your axels falling apart at the track man Or just go for a 9 inch rear Also UGH LOW PINYON REARS!

[@leefhead1]

Fifth! Thats how people comment on youtube videos, right?

[@scadieee]

Could of just imported an Terminator perhaps. Would of seemed like a better chassis to start (mustang wise) with but then again it's probably expensive compared to here in the States

[@andrewfox96]

You think with the time you spent on the swapping the rear end, would've been easier to get a torsen t2 a complete set up than the rebuilding kit.

[@joshweisgerber6461]

omg no no no no!!!!!! you must Must MUST re shim the pinion! having it shimmed how you are WILL!!!! DESTROY The ring gear! you must center the pinion and set the drag on the pinion minimum 6in lbs! sorry not to rag. I love your show but please call these people who sell you it and go throu every spec and step.

[@ceralkill3r]

never ever put the mating surface of a diff on a vise.... it is an extremely fragle and precise surface

[@boblast5582]

Mr. CriticizeEverything here. Why didn't you guys just go with a better LSD? an Eaton TrueTrac is only like $400 bucks and you don't have to worry about rebuilding it or clutch disks wearing out. its what I had in my Mustang

Hey Canadians this isn't rocket science it's a Mustang

[@robertherndon514]

I run 4.30 minimum in my street-driven 4.6 3-Valves.....4.10 is nowhere near enough....IMHO.

[@robertswift6101]

nowhere near enough what?

[@Ryousure]

Need S2000.!!!

[@dominikhofmann603]

I'd trust pete's eyes more than those chinese digital calipers ;)

[@UndergroundTrev]

"Speed Academy- Fast Cars, Built Right" . . . unless you're rebuilding an SR20DET, or a rear differential, because f#@k engines and differentials! (PS, I love you're channel! You just might want to change your catch phrase or stop hacking shit) (PPS, please take the time to get the pattern on the ring gear correct, it's worth it)

[@saby8765]

Top mount for rear diff? Bruh, that's called a upper control arm

[@michaelallen2501]

Ditch that failure prone 2 piece driveshaft for a 1 piece aluminum. Pick up ponies with your insurance too.

[@alex_r5896]

You guys do half ass jobs a little too often.

[@willknights853]

Lmfao he shot that thing out

[@UnratedRetribution]

Guys why do you have to say GD in every video
