Removing diff output shaft bearings

PostPost by: vernon.taylor » Wed Apr 04, 2012 6:11 am

Salut

Along with Leslie's lovely looking diff, I managed to find a good diff case and late output drive shafts for not much money (always nice whan that happens).

The output shafts still have their bearings. How does one remove them, please - and put new ones?

I read up how to put things back together on the forum and am currently and discretely emptying the freezer :o

Here ya go Vernon

This is the disassembly part. The assembly part is going to wait for a couple days till I get ready to press things back together again.

This had been on the shelf for a while, If I were actully removing the bearing I would clean the rust off the output shaft before pulling.

You will need

two new bearing 6202-rs2
two new seals, I beliewve they are 40 x 30 x 7mm
and a good press to reassemble.

The bearing puller does not need to be as large as what I show but to do the drive axle it does so buy a big one.

Merci, Gary. Got the circlip pliers but not the puller. I'll have to be careful when I ask for one in a shop - if I make a mistake with the French translation, it might sound like 'dick puller' :shock:

I searched the forum, both with the internal search engine and Google and didn't find what I was looking for. I'm going to ask the question here because it pertains to the same job and the thread is fresh...

I'm trying to remove the drive axles from the diff. The manual directs you to remove the clip and "gently tap" the axle out. That clearly wasn't written for my +2 that has been sitting for thirty plus years. I have removed the clip and cleaned the housing around the bearing. The housing is clean and not corroded, but the face of the bearing is clearly rusted. The gentle tap method isn't working. Right now both bearing faces are soaked down with PB Blaster while I regroup. I've seen pictures if blown out ally housings (thanks Gary) and don't want to go that route. There has to be a better way than just using a bigger hammer.

Any suggestions??

Hi Bud,
I had to use a bit of heat on the diff casing & a slide hammer.The slide hammer tends to keep the pulling force in a straight line
so less chance of shattering the diff casing.

If it isn?t coming out easily you haven?t applied enough heat to the aluminium. If it has been stuck in with bearing fit, that lets go at about 200 oC

This is the best advice I have read here, I agree 100% with both posts.

Thanks everyone! Heat was the missing element. A few seconds with the MAPP gas torch and they popped off cleanly with the slide hammer.

I was only taking the diff apart to change the gasket and seals, but found one bearing completely shot. Wonder what I'll find when I disassemble the trans to change those gaskets and seals. :shock:
