Front Differential Axle Shaft Oil Seal Replacement

Did our video help you? If so, consider buying us a beer: bit.ly/3feE6tJ
In this video, we show you how to replace the front differential axle oil seals on a 3rd Gen 4runner. We don't show the removal and reinstallation of the CV axles because we show that in our CV Axle Reboot and Replacement video:

You're welcome Tim. I would guess you are not the first nor will you be the last that makes this mistake. It's nicer when the seal driving is much more straight forward and you can just bottom it out.

Yup, drove it in until it seated. Realized I was wrong, pulled it out and had to replace it with a new one. Toyota is known for their engineering skills but someone dropped the ball on this design.

[@Steve-yl1yg]

I had to recently change the CV axles in my 06 GX470 and used you're other video to accomplish that task. Unfortunately, the passenger side decided to start leaking. Thankfully Timmy and his buddies made this excellent tutorial! Best videos on KZbin...you need the highest award! Much appreciation Sir!

[@TimmyTheToolman]

Thanks Steve. We appreciate your nice compliment of our channel. We actually replaced the differential axle seals on Thanh's GX470 because one of his seals started leaking too after we swapped out the axles. We used a new installation tool make by Wit's End which made the job much easier. Check out the video: kzbin.info/www/bejne/h161gGhog9mDZ6M

[@SimpleBelieverInChrist]

I'm elbow deep in this project right now. I appreciate all the tips, especially on how to seat the new seal. One point that's worth mentioning - if you decide to use a prybar to remove the old seal, be very careful not to scar the housing where seal sits like I did. It's worth buying or renting a slide hammer! Also, if you don't have a depth guage to measure the 5mm depth of the seal, get a tire depth guage from the auto parts store, they're 3 dollars.

[@TimmyTheToolman]

@@SimpleBelieverInChrist Yep, you have to be careful with the hooked style seal pullers.

[@anthonyreddy2834]

I bought a seal driver kit, all the drivers are flat, the seals are raised away from the metal part of the seals, I then watched this video and at first I was going to do what you did but with a piece of 3 inch diameter pipe but I watched another video on this and the guy(cant remember who) used a oil filter wrench/socket that worked perfectly. I could tap in the middle or sides. Made it simple. Great video as usual!

[@TimmyTheToolman]

Hey Anthony, the oil filter wrench socket sounds like a good technique. I guess you just need to buy the right size oil filter socket for each side since the the driver and passenger side seals are different diameters. There's always more than one way to accomplish something. This is especially true with press work. Guys come up with all kinds of ingenious ways to get things done. Thanks for sharing this technique and we're glad you like the video. Happy Wrenching!

[@anthonyreddy2834]

Yeah, I only had issues with passengers side, had plenty of pieces of pipe and sockets for drivers side. Peace!

[@MrNewff]

I just tried this. I was having trouble getting the jaws to tighten/widen inside because that round lock nut thing you are using there was just barely able to get on the outside of the back of the jaws to tighten it. I found once I had some of the rubber removed from the seal to give more room I was able to widen and tighten that nut more to widen the jaws inside. Thanks for the video. Finally just got mine out.

Thank you for your awesome videos! They are so helpful! I couldn't have done this job, and most other jobs, without your help. You provide accurate information and instil confidence that I too can do such jobs. Thank you!!! I finally got around to replacing my leaking CV shafts and oil seals. That right side (driver's side for me) oil seal wasn't easy, eh! The first time it wasn't straight, and leaked. New oil seal again. The second time I knocked it in too far, and it leaked. New oil seal again. Third time I think I've got it, nothing is leaking after 200km of sand and 400km of highway. Timmy. I think I may have set off a little debate, too..... sorry about that. I wish I lived closer so I could buy you a beer (or a slab) to apologise properly.

[@benzoil0453]

Hey Tim. There was a guy who left a comment on one of these CV axle or front diff seal videos of yours who said he had a difficult time removing the CV axle and he had to remove his shock as a result of that. I actually ran into the same problem this morning on my 2000 Tacoma 4x4. I had the Hub completely pulled out of the way with baling wire and also had my floor jack kind of supporting it to relieve the tension of the brake line. The axle was getting hung up between the bottom of the shock and the sway bar link. I tried every which angle to get that thing out of there and could not. I was just getting ready to remove the shock and realized it would probably be easier to disconnect the sway bar links on both sides, swivel the sway bar up, and swivel the end links down. That created plenty of room to pull the old axle out. This was on the passenger side. I will be doing axles and seals on both sides but just wanted to throw this out there for anyone who is running into this issue. Thanks again for these awesome videos!

Thanks for the video. My daughter purchased a 1998 Toyota Tacoma 4x4 Extra Cab. The Front Differential Axle Shaft Oil Seals are leaking on both sides but, much more on the right side. It leaks differential fluid after the four wheel drive has been engaged for a brief period. When four wheel drive is not engaged, the leaking stops. I have done my own DIY repairs myself, like replacing brakes pads, radiators, alternators, valve cover gaskets. Replacing the Front Differential Axle Shaft Oil Seals, on my daughter's 1998 Toyota Tacoma, looks like a job for a skilled mechanic and not a job for me.

Tim- OUTSTANDING VIDEO!! You are one of the BEST published, professionally produced videos for Mechanical repairs on UTUBE! I have subscribed and "liked" your video !! I have a question, regarding the replacement of CV axel on Landcruiser/ LX 470. I just did the passenger side and replaced the oil seal as well ( it was leaking) I got a remanufactured Toyota OEM drive shaft ( I very much dislike the aftermarket cheap crap that's 1/4 the price of OEM products ) When I was installing it, my assistant put a block of wood over the end it, and hammered a few times with a regular claw hammer. It did not go in and the C clip on the diff side of the spline is designed to hold it IN!. I did more research and found a video that used a drift punch or pry bar and place it on the lip of the large circle and hammered it on that small lip with a 2x2 or metal drift punch. THAT WORKED! My question is, did pounding a few times on the end of the CV shaft damage it ?? IT has some linear play in it now,( under the inner side boot) so I am really nervous if it's damaged and working? I reinstalled both Ball joints and torqued to factory specs. I know after I reassemble everything i will know in a second if it's broken. BTW - I have never replaced a CV axel much less on a 4 wheel drive LX. I'm kind of stuck now and REALLY need a prompt response so I hope you check this site or get a notification daily Look fwd to your reply on what i should check, troubleshoot or what... i should do to complete it today Thank you Tim

Hey Tim excellent video! Im doing mine today. I have a 97 T100 3.4l 4x4 my fam and I ran her silly in Big Bear this last week..snow, much, mud and some gritty rocky paths! She handles super solid. Until I ran her into a 4' water hole and got her jammed up for a bit. Couple folks came down the path and Wenched us out no problem. Then I ended up with a front pass. Diff leak. From what I read, a blocked breather valve? On the front diff...can you do a video or maybe spare a quick tip on unclogging and or preventing another seal blow out? Thanks again Tim! Appreciate your thorough real human perspective!

[@TimmyTheToolman]

We probably wouldn't make a video on the topic of a clogged breather because it's pretty basic. You find where the breather is located, pull it off the line and blow through it. If air moves through it, it's good. If air doesn't move through it, you replace it. On 3rd Gen 4runners, the front differential breather is extended onto the inside of the driver side fender in the engine compartment. Maybe Toyota put it in the same place on your T100. If it's not in the same place, get under the rig and take a look where the breather is. It shouldn't be that hard to spot. You're seal could have just worn out too. Seals fail from miles and old age. Glad you like the video and Happy Wrenching.

[@andrewm.4168]

An easy way to seat the seal is put it in freezer first to shrink it. Then you can begin to seat it with your fingers. Then, take your old seal, cut the rubber dust ring off, and it will lay over the new seal so you can hit it to drive in new seal. An easy way to drive it in is get a 2 foot or so 2x4 and it will extend far enough out of the wheel well to hit the end of the board with a hammer. Easier than trying to tap it with hammer with lower control arm in the way...

[@rhymeswithteeth]

If the seal is to fit at the same level as the outer ridge, you could use a sleeve that, not only, fits the diameter of the seal but whose sleeve walls are thick enough to extend out further to meet with the outer ridge. That way, there would be no way of installing the seal beyond the outer ridge. Also, if your sleeve was shorter in length, you'd have more room for hammering. A sleeve (like what I've suggested, above) could be made by gluing one diameter of PVC pipe inside a wider diameter of PVC pipe. $2?

[@TimmyTheToolman]

That's an excellent idea provided you could find the right size PVC pipes. PVC pipes come in definite industry standard diameters so you might not find two that will work perfectly for this application.

Nice video, and very informative, you've just earned a sub, and if you could it would be great to see a video on how to change that needle bearing. And is that the needle bearing that we are seeing the oil seal go around?

[@TimmyTheToolman]

Hey Tyler, I might be helping a guy install a front differential "Clam Shell" equipped with an ARB locker but I don't know if this mod will include replacing any bearings. The oil seal is not really going around any bearing. It's just seated into the ends of the differential housing. There are bearings inside the housing just past the oil seal and that must be what you're talking about. So, if his bearings are fine, I doubt we'll be replacing them. But, who knows. I might find a local 3rd Gen owner that needs this repair and we'll do it for him and make a video of it. Thanks for subscribing. We've got lots of good stuff coming.

We've replaced the driver side needle bearing before with a special extraction tool made by East Coast Gear Supply so we could install an ECGS bushing to reduce play with the CV shaft in the differential.

Hi Tim. Really need your advice. I had the same experience with ripped CV boots after suspension lift but I replaced mine with aftermarket ones. I replaced both seals and may have over filled the diff. I now have fluid leaking out. At first there was quite a bit of fluid from both sides but now its just on the passenger side and only when I drive it. Could it have been from over filling the Diff or should I just replace the seals again? my real concern is, if fluid is leaking out then water can get in. Your opinion is much appreciated and respected!!

[@TimmyTheToolman]

@gbrianmullinax8448 With overfilling the differential, you would usually see it spewing out the breather that is attached to the driver side fender in the engine compartment unless the rubber breather tube became disconnected from the nipple on the top of the differential. Have you checked to see if the breather is working by blowing through it? Have you checked the top of the differential for signs of gear oil leaking out? It could be a breather or breather tube issue and not the seals. I'd rule those possibilities out before replacing the seals again

[@gbrianmullinax8448]

@@TimmyTheToolman I looked and it appears the breather tube is connected. I don't see any signs of gear oil at the point of connection.

Timmy The Toolman Hi Timmy Just recently Replaced My Cv axles, Lower Ball Joints, Inner and Outer Tie rod Ends For My 97 Toyota 4Runner Sr5 Just had an alignment. Drives great.. Beyond and behold The driver side axle shaft seal On the differential started leaking.. I have a New seal Ordered and ready for pick-up.. I recently watched this your video. So Im going to attemped to give it a try.. My question Is Prior to removing The cv axle Is it possible to just loosen and remove the 4 bolts attaching Lower balljoint to hub or would it be better to Loosen and Remove the 1 lower Nut and leave ball joint attack to The hub..I guess I'm trying to figure out the Best way to go without messing with anything that could effect the alignment Or is A alignment required reguardless. Thanx

[@TimmyTheToolman]

Hey Heather, whether you disconnect the lower balljoint at the lower control arm or disconnect it at the steering knuckle makes no difference. The alignment will not be affected. The only way you'd affect the alignment is if you loosened the cam adjuster bolts on the LCAs and turned the cam adjusters or you loosened the set nuts for the outer tie rods and adjusted them. I prefer to just take off the castle nut and break the connection at the LCA with a puller and leave the 4 balljoint bolts alone since I loctited them. Good luck with the axle seal repair.

[@Sortawickid]

Thanks Timmy I hope all goes well also..Thanks again.

[@TimmyTheToolman]

Just take your time driving in the seal and you'll be fine. It's tedious but just keep rechecking the depth as you're driving it in because you don't want to overshoot. If you do, you'll have to get another seal, because the seal gets destroyed pulling it out. If you're off by a little bit, you'll probably be fine. But, if you drive it in way too far, it won't meet up with the CV axle well and it will leak.

You would have to press the hub out of the bearing to replace the dust shields. And, because you pressed the hub out, the bearing gets destroyed. So, you have to install new bearings, associated seals and snap rings to do it properly.

Hey Bardia, amazingly it is. I asked Eric if he had ever checked the front differential gear oil. He said no and he's owned the truck for 2 years. Who knows how long that differential was low on gear oil. I asked him if he had been using 4 wheel drive and he said he had. He likes to go snowboarding so I imagine he has been using it when he goes up to the mountains. This just proves how important it is to check over a used vehicle after you buy it. One of the first things I did when I bought my rig was replace all the fluids in the engine, transmission, transfer, and differentials to start off fresh. Who knows how long his front differential will last with the damage it sustained by running low on gear oil.

I'm guessing Eric didn't have a diff drop put on? What are your thoughts on them? It seems like some people like them and others don't for potential bigger problems down the road. Another great video!

[@TimmyTheToolman]

Hey Jesse, Eric does have a differential drop, but from what I understand, you can only drop the differential 1 inch. That still leaves a 2" difference with a 3" lift in the front. So, even with a diff drop installed, you could still have CV axle boot ribs that are rubbing together. The fix is to stretch the boot out a little farther so the ribs won't touch each other due to the steeper angle the CV axles now have. We show one way to do a boot stretch mod in our CV Axle Reboot video: kzbin.info/www/bejne/rJSmhWeLnKuIitk I don't know what potential problems you could have with the differential drop other than you need spacers to put your front skid plate back on right. If I put a lift on my truck, I'd use a diff drop to improve the CV angle. When Eric comes over my place for some more work, I'm going to try another variation of the boot stretch mod that you can do without removing the CV Axle.

[@JesseVM]

Timmy The Toolman I just watched your CV reboot video. Once my OME lift is installed I'll keep an eye on those 18 year old boots. Once the weather warms up I may just reboot them in case they do split and wear down the internals. Thanks again!

[@TimmyTheToolman]

No problem Jesse. Definitely keep an eye on those inner CV boots after you lift it. They are known to tear right near the small clamp on the inner boot. The new angle is too much for the old boot to take and they rip. You want to catch it quick so you can save your OEM axles and be able to reboot them.

[@TimmyTheToolman]

Hey Jesse, I recently worked on Eric's truck again and I noticed his inner CV boot ribs are not rubbing but the outer boot ribs are definitely rubbing. I suspect he'll have a premature failure of the outer boots because of it. The boot materials are very different though. The inner boot is a rubber compound while the outer is a plastic compound. I'm guessing the inner boot is rubber because that joint can slide in and out and thus a more pliable material is needed. The outer joint just turns and doesn't have to elongate so a stiff plastic works fine. I've personally seen more inner boot failures so I'm wondering if the outer plastic boot is a little more durable than the inner rubber boot. I guess time will tell. So, I think the differential drop helped keep the inner boot ribs from rubbing by lessening the angle.

[@JesseVM]

Well my inner boot on the drivers side gave up the ghost. Small amount of tan coloured grease... Also my passenger side front diff seal is leaking gear oil slowly. Might as well bite the bullet, reboot both sides and change that seal while I'm there! These videos will be a huge asset! Thanks Tim and Sean!

I pressed my bearings in today and I noticed the same thing happening, you can turn the tone ring along with the retainer and the wheel wasn't moving, seems pretty strange. It looks like pressing in bearings on a 4runner is a science.

[@TimmyTheToolman]

Dude, this is weird because I was just pressing front wheel bearings yesterday but it was for a guys project for putting manual hubs from a Tacoma on his 3rd Gen 4runner. I unfortunately don't have experience with the 3rd Gen hubs yet. You lost me on the tone ring but I looked it up and it's synonymous with the ABS sensor rotor. Next to the ABS sensor rotor is a bearing spacer (at least that is what the FSM calls it), is that what you are calling the retainer? When I did a CV axle reboots and replacements, I had noticed something in the back of the hub that was moving freely. It must have been the ABS rotor and/or retainer. Sean has a set of knuckles we pulled off a wrecked 4runner at a local Pick and Pull. I'm stuck at work for the next couple days but maybe I can have him take a look at the knuckles and take some pics for me and tell me what's actually able to move on the backside of the hub.

It doesn't hurt to add some pre-assembly grease to the seal lip so the first turns the CV axle makes doesn't cause any excessive wear. Once the vehicle starts really moving, gear oil is constantly up against the seal keeping it lubricated.

Nice work. Q. i've done a rear seal on my 96 4runner but i need to do the front p/s of my 04. any tips how to do the 04?

[@TimmyTheToolman]

I don't have a Factory Service Manual for an 04 but I imagine it's probably very similar. Remove the CV axle, note how the seal currently sits, maybe even take a measurement with a caliper tool like I show in the video, pull the old seal out and knock in the new one at the same depth. You should be good to go.

[@signsofthetimes886]

Can you do this job with a oil removal tool that has the hooks? Or is it better to buy this tool?

[@TimmyTheToolman]

Sounds From The Underground. You can use a hook style seal puller. The slide hammer puller is a more versatile tool but not absolutely necessary for doing this job.

Would this work same way for a 86 4runner

It would be very similar. Just pay attention to the depth the original seal was installed to and replicate it.

I need to do both sides on my 95 Tacoma 4x4. My guy is charging me $250 in labor, is that fair? Thank you

[@TimmyTheToolman]

I'd say that's a pretty fair price. It'a decent amount of labor to pull the CV axles, pull the seals, accurately drive the seals in and get it all back together.

[@raydonovan7988]

I am going to be replacing this on a 2007 fj cruiser. Do you know if it is a similar job for a 2007 fj cruiser? Does it go in 5.5mm also? I cant find much online

[@TimmyTheToolman]

Any vehicle with CV axles should be very similar. Now how far should you drive in the seal? Can't say its exactly 5.5mm. What you should do before you remove the old seal is try to measure it or at least take a visual note of how far it is driven in & attempt to get it back in the same position. It's important you have a tool to drive in the seal evenly so try to find a seal driver kit like the one we link or gather something together that will be a slightly smaller outer diameter of the seal.

[@Yotapuga]

Should I replace them if I'm recently replacing the CV axles? Had no prior leaks but would it be worth it?

[@TimmyTheToolman]

If they're not leaking, don't bother. I think these seals can last a long time. Pulling the CV axles out isn't that labor intensive, so if you ever do develop a leak, it's not a big deal to pull it again to replace the seal.

If you made your own press tool with a stop on it at 5.5mm, that would make things easier.

[@TimmyTheToolman]

I don't need to make it. Wits' End already did. absolute-wits-end.com/toyota-4wd-ifs-output-shaft-seal-driver/ Paired with this extended handle absolute-wits-end.com/extended-handles-for-seal-drive-tools-18/ it makes driving in the seals a breeze.

Ok thanks for your video. I have a 2006 armada LE, front driver side axle shaft is wobbly on the inner end, does it mean it’s the shaft that needs replacing or the bearing inside? Also can I drive the car with that particular shaft out of the car?

[@TimmyTheToolman]

My guess is the bearing inside the differential is bad on that side. I suppose you could drive it with one shaft out but you'd then lose gear oil and provide a way for dirty and road debris to get into you differential. I guess you could stuff a rag or something in there for the time being while you figure out what you're going to do. The best option is to fix the problem and put the axle shaft back in before driving it.

[@andyfumo8931]

@@TimmyTheToolman again? Please stop recommending these dangerous options. It IS NOT ok to drive with the shaft out, how can you possibly justify that option, regardless of customer circumstances. Correct these errors please.

@@andyfumo8931 Desperate measures call for desperate acts. Did you read my response? By no means am I recommending this guy do this. But, say this is his only transportation and he wanted to drive his vehicle a short distance to an auto parts store, stuffing a rag in the open side would work for a short time. When 4wheeling, guys break all kinds of shit and they piece it together the best way they can and get back to civilization. So, ease up there Andy. I'm not telling the guy to jump off a bridge.

mine leaking too but the cv axle play and move so do i need to replace the cv axle as well?

[@TimmyTheToolman]

There's some play at the connection of the CV axle to the differential. Sometimes gross play can be experienced at the driver side connection because there's a needle bearing that wears out. A common fix is to install an East Coast Gear Supply bushing in place of the needle bearing. We have a video for that job. kzbin.info/www/bejne/qYmsl3t3p9mpfJo
