This is a step by step instructional video on how to replace the axle seals & bearings in a Ford 7.5 & 8.8 differential. While I’m working on a ’98 Ford Mustang, this video applies to many Ford models & years since these rear ends have been in use for decades.
I show many tips & tricks as well as the tools needed to make this job quick, easy & painless. The actual labor part of this job takes about 10 minutes per side (not including removing the axles etc). However, the total time (including removing and reinstalling the axles) depends on if you use a regular gasket or RTV for the differential cover gasket and can range from 2 to 24 hours.
If you need instructions on how to remove the axle shafts, see my video titled “How To Replace Spider Gears In For≈d 7.5 & 8.8 Open Differential - Ford Mustang":

Hi Pet Rock's Garage, so I’m in Canada I went to NAPA with no luck but Canadian tire loans out the tools at no charge, just a deposit that is paid back in their return. I already had the axel out for my drum to disc brake upgrade in my 1986 Mustang. The bearing removal and install took about 20 minutes with the right tools. Thanks again for your detailed step by step this was a lot easier than I’d thought it would be. To think I was going to leave the old leaking seal and worn bearings in place and not use the new ones provided in the brake upgrade kit . For some reason the past car owner packed the one seal with thick grease to prevent gear oil from leaking out - ouch so glad I did this now and lol that was easy. Thanks again. Cheers, Hans

Again thanks a lot for the video! Just a quick tip cause I had very hard time to remove the seal on both side as it was stuck there. I used the slide hammer with the bearing puller and remove the bearing and the seal at the same time and it works perfect 👌! Just a tip to prevent damage on the axle tube by trying to pry out the seal ;)!

Yeah, you can remove the seal & bearing at the same time with a slide hammer. It's a perfectly valid technique. However, it only works if you are replacing the bearing too.

@MrSlowestD16 3 жыл бұрын

Looks straight forward enough. Thanks for the very clear directions. I've also heard people say put some black RTV around the axle seal. I have to do this as my right wheel bearing is making noise + my pinion seal is leaking as well, my car is lowered a bit so it's real hard to get to the top fill plug of the diff. Furthermore, my driveway is on an angle so I can't properly fill it. Between needing a lot of torque on the pinion nut to crush the pinion sleeve + the fill plug hard to get to + needing the diff level when I fill it I want to remove the rear axle and do this job + the pinion seal outside of the car. What are your thoughts on doing it? On one hand it seems like massive overkill, but on the other it sorta sounds like a massive pain in the ass doing it on the car on my back in cramped space. Thoughts?

@petrocksgarage 3 жыл бұрын

Thanks a lot. Re RTV: if the bore that the axle seal goes into is damaged then you would want to use RTV. Otherwise, you don't need to. Re getting to the fill plug: if you put all four corners of the car up on jack stands at roughly the same height, it should make it easier to get to. Or use a really long hose attached to a pump like I used in the video. Having your driveway at an angle actually makes it easier. Have the rear facing down hill and jack it up until the car is level. Make sure to block the front wheels so the car doesn't roll. Re pulling the axle to service it: that might be more headache then its worth. If the driveway really is a problem I'd find a level spot somewhere nearby to do the job. My driveway is also at an angle. I've sometimes rolled it back so the rear wheels are in the street and the front are on the driveway to get it close to level so I can check the oil. Works pretty well. Maybe that technique would work for you too. Good luck.

@MrSlowestD16 3 жыл бұрын

@@petrocksgarage The really long hose probably would have helped, I'll get one of those. I had just used a shorter hose + squeezing a regular gear oil container to top it off and it was a huge pain in the ass because it was slow as shit & hard to squeeze. The long hose + pump looks like a significantly better option. Yeah, that's a good point about parking it up-hill and doing it that way. I had wanted to do it downhill because it puts the rear near my tools, but I think your way is better because it allows me to balance while creating room for myself. I did the math and should only need to come up about 10 inches max to be level. OK, I'll have the RTV on hand if it's damaged and I need it, otherwise I won't use it. OK, you've convinced me on trying to do it with the axle still in the car! It should make the job considerably easier. If I run into issues I can always drop it after. I was most concerned about the pinion seal and crush sleeve, but I did some searching and looks like a pretty quick/easy weld to make a make-shift pinion holder tool that can rest against the ground or car body while I crank the pinion nut enough to crush the sleeve, so that should make it much more manageable from under the car. Thanks!

Didn’t want to use the bearing puller to remove the seal and the bearing all at once? Works like a charm..

@petrocksgarage 2 ай бұрын

Yes, that is an option. But in my experience the bearing often just pulls through the seal on some vehicles and makes the seal harder to remove afterwards. So I typically just pull the seal separately. Also, the video shows how to remove the seal if that is all you are replacing.

@sham_wow_guy 2 жыл бұрын

Some advice for others looking to do this. You can just leave the seal in place and it will come out when you pull the bearing. No need to remove it first.

@petrocksgarage 2 жыл бұрын

While it doesn't hurt to try, in my experience it only works sometimes. More often than not the bearing will pull right out the middle of the seal. Especially if the outer flange of the seal is rusted to the axle tube. IMS, the bearing is a slightly smaller diameter than the stiff/metal part of the seal. Either way, I showed it the way I did for those who are just replacing the seal.

@driftingpickup5955 7 жыл бұрын

I'm working on a 98 mustang and the previous owner hit a curb so hard he broke the axle and knocked the wheel off. It didn't even have a seal on it and the bearing was cracked. The opening for the axle housing was bent and out of round but II was somewhat able to hammer it back in place. So there are a couple rough edges that could be filed and maybe a little more hammering. I can show a picture. Do you think this is a fixable situation or do I need a new axle?

@petrocksgarage 7 жыл бұрын

IMO, I would replace the entire differential. If he broke the axle (which is a solid piece of steal) then he hit it pretty hard and all that force went into the gears & bearings in the differential housing, likely bending/damaging something. But if $$$ is an issue, then you could try to rebuild it. I'd advise using some RTV around the outer edge of the axle seal to fill in any imperfections you couldn't hammer out. I would also take the diff cover off and have a look inside to make sure that there are no other broken or damaged parts in there. Make sure it spins freely with no noise or anything like that. Good luck.

@tjames975 3 жыл бұрын

I wasn't able to seat my bearing as far as yours at 6:50. I can see the lip but not as much, and one side I just barely see it. There's like a ramp in the back. Do you think I should pull the seals and hit it some more, or just chalk it up to different tolerances?

@petrocksgarage 3 жыл бұрын

The important part is that the bearing is in straight. Make sure that the amount of the lip you can see is the same all the way around. If its not then the bearing is not in straight. If it is the same all the way around you should be ok. The seal shouldn't come in contact with the bearing, so it should be ok too. Good luck.

Well, first I'd get the seal out. Maybe use a small pry bar, screw driver, seal puller or whatever method. As for the bearing outer race (the shell), it sounds like you used too small a puller. The puller should be in contact with the outer race. If that fails, then its really hard to say what to do from my keyboard. With whatever method you use, make sure not to scape up the inside of the diff tube in the process. Good luck...

@@zachensley9386, the motor doesn't effect the oil used in the differential. I use 75W-90, but any gear oil around those specs should be fine. Also, if you have a limited slip differential you should add 8oz of friction modifier first and then fill the rest of the way with gear oil. If you don't know if you have a LSD or not, the easiest way to tell is to jack up the car and spin one of the rear tires. If the other wheel spins in the opposite direction, you have an open differential. If it spins in the same direction, you have a limited slip differential, or LSD.

@petrocksgarage 7 жыл бұрын

If you can get the puller tool in there, yeah, it might work. It will be harder though and you risk breaking the puller tool because you need to tighten the puller onto the thing you are pulling out (e.g. the bearing). With the seal in the way you can't cinch the puller tool down properly, so every time you pull on it with the slide hammer you will be be slamming the tool against the back side of the bearing, which is not how the tool was designed and it could break.

The best way is by looking at the metal tag on one of the diff bolts. It should have this info. If that tag isn't available, you call your local ford dealers parts department and they should be able to tell you from the VIN. A less reliable method is to look at the differential cover. Does it look like the one in the video (same bolt pattern)? If so, its likely a 7.5 diff. If not, its likely an 8.8 diff. Hope that helps.

You can try and it may work. It's been my experience that the bearing will just pull out through the seal because the bearing is a smaller diameter than the metal part of the seal. If that happens it makes removing the seal significantly harder. Either way, I show this method to include those that are just changing the seal. Good luck.

I don’t think you pounded the seal in all the way. The inner lip your seating against is deeper. If you look at the seal before you moved it it looks deeper, maybe an 1/8 of an inch. It only matters because the axle is usually not as smooth outside The old seal ring, and the new seal ring is further out trying to seal against rust. I did the Same he thing on my first one.

No, its in as far as it needs to go. The old seal had a lip on it to prevent it from going in beyond flush with the axle tube (@3:26), I installed the new seal the same way, flush with the axle tube. While there is a little bit of wiggle room in how far you drive it in, you can go too deep. If you drive it in too far it will come in contact with the rollers in the bearing and can chew up the seal housing pretty quickly.

@@bmfbbmfb, they may be slightly different. Definitely different diameter axle tubes. The pic you reference is of a new aftermarket seal though, not the OEM seal which has a lip. And there is another picture in that grouping that has the aftermarket seal flush with the tube. But you are correct in that you don't want the seal riding on rust. If that is a concern I'd advise taking some emery cloth and cleaning up the sealing surface before install. I wish I had put that in the video.

6/20/2020 Next time, clean the parts around the seal, before you remove the seal and bearing. Also, instead of pre-lubing, why not just lube the seal and bearing?

@petrocksgarage 4 жыл бұрын

Not sure why it matters to clean around the seal before removing it as long as you clean it before installing the new seal. as for pre-lube: pre-lubing the seal & bearing is lubing the seal & bearing. I don't understand the question.

So I took my car into the shop today and got the 3.32 gears replaced with 4.10's They gave the car back and said I had a bad rear axle bearing. I get in the car, tune the computer for the new gears. And drive off. I got up to 40mph just fine and then let off the gas and this jake brake sound comes from the rear of the car. At first I thought the differential was going to explode. So now looking at this video they are going to have to break down the entire thing again just to replace wheel bearings that were perfectly fine when I dropped my car off.FML

That bearing he's pulling out looks like a repair bearing, hence why he couldn't pull out the oil seal as it's all one piece with the bearing.

@petrocksgarage 3 жыл бұрын

I'm not sure what video you are commenting on. The bearing & seal I pull out are clearly two separate parts in the video. By pulling them individually the video is useful for those who just want to replace the seal and not the bearing. Either way, I don't like pulling the bearing & seal as a unit because more often then not the bearing pulls right through the seal making it harder to remove the seal afterwards. But if you want to pull them together, go for it. There is nothing really wrong with it. I just prefer to pull them separately.

Lol Those Axle Seals are sometimes glued in the Housing take small Chisel hit the edge of the Seal and be Careful of the Axle Housing Collapse the Seal on one Side than use BFG Pry bar pry the Seal out and don't Gouge the inner Housing if you do clean Very well with Brake Clean after installing Bearing use little RTV Silicone Glue on Outer edge of Axle Seal and White or Axle Bearing Grease on Inner lip of Seal Apply Grease on the Bearing Rollers the rest you should Know. Use High Quality 75w-140 Synthetic Diff Fluid. I'm Master Mechanic I was Browsing on the Tube see how other guy's do it never know people come up with Different ways Good or WTF?

Yes, that is an option if you are replacing both the bearing & seal. However, I chose to show how to replace the seals individually for those that may be just replacing seals.
