rear axle bearing/seal replacement

[Sasquatch_Ryda]

If you have the bearing fall apart like that and have access to a welder, run a bead of weld around the inside of the bearing where the rollers would have been. The bearing will shrink and pretty much fall right out. Just and FYI.

I used a 5/16 combination wrench instead of a socket to remove the pinion shaft lock bolt to avoid rounding the head or breaking it off.

You know what....I keep reading this and reading this on here, but I've never seen this yet at work...and I probably pull apart 2-3 8.8 or 7.5's a month.

I've seen it a few times but it's not at all common for me either. I'm not really sure why some guys have it happen so much. I'll never understand how they get broken either but they always break right at the end of the threads and just the pin portion with maybe a 1/2 thread stays in the carrier. I can usually spin them out with a pick.

I never had a problem until I took mine to a shop and had the gears changed from 3.45 to 4.56. They shaved the cross pin down, and of course it broke.
Guys on here shaved a little bit off of the ring gear, and about 15k's off of the cross pin and it went right in. I copy catted them.
After refining and improving their process 3 x's. Now I am replacing bearings all over the place. Wish I had done this sooner.
It appears pieces of broken cross pin are bad for your bearings! LOL!

I'm posting this for other guys that may use this thread to change theirs. FIRST be careful if you have the stupid plastic diff cover. I had no clue mine was plastic (covered in dirt) and after a couple whacks getting a screwdriver in there to top it off, it started to crack so I had to buy a metal one. Secondly, you do not need to get the seal out before you take the bearing out. I rented a slide hammer and bearing attachment ("T" style) and with a few hits it the seal and bearing came out. Other than that, all good. Well besides that my fluid was 25 years old and was burnt to all hell. Luckily my diff bearings are ok.

I know this is an OLD thread but wanted to ask the question.

I am in the process of changing out rear axle bearings (not bad), but also replacing since I am doing the seals, but my seals were leaking on the driver side rear... it's original seals from 2001...lol

I forgot to note which way I pulled the bearing out and it appears that one side is slightly more curved than the other.

does it matter which way the bearing is put back in?

I have taken a couple pictures.

Thanks,

I'm not sure if it matters? But I've always done these with the numbers/marking facing out.

I've seen mention of the 'repair bearing'. I've never had good luck using those. My BII we retired got one installed, and it ate itself a day later. Did the correct repair and replaced the shaft and used high quality bearings and seals (national/timkin)

The Exploder we just put on the road we are working with-- the PO put on a repair bearing. Due to the extended width that really just about welds itself in place. We had to use a small cut off wheel to notch out the outer bearing race.

bumping....planning on replacing my rear bearings in my 7.5 soon. Not a huge Ford person so asking a noob type question. I recently replaced my rear brakes drums/shoes etc...and as one could guess I said hmmpf!! Shoulda changed the rear bearings while it was apart. I found the bolts holding the axle in. I am needing to know if their are clips inside the diff to remove as well? My Dodge had both clips and bolts.

Thanks to anyone who gives a shout out

There are no bolts holding the axles in. Only the c-clips inside the housing.
