Removing rear wheel bearings.

[Fortlauderdalian]

I’ve gotten as far as removing the hub. What’s the next step? I couldn’t find a video

Put the nut on backwards, pound out the stub axle, remove inner and outer seals, remove bearings.

You are going to need more than some videos to successfully complete a rear bearing replacement. New bearings must be shimmed properly, bad things happen if not done correctly

Make sure you keep each shim matched up with its corresponding hub side as well - very important.

Measure ypur old bearing width and compare it to the new ones if they are the same then you can reuse the shim pack for each side. The shims are more for machining differances than bearing width variation.

How does the splined shaft come out? 

[Rodolfo Lasparri]

The shims are matched to the trailing arms, you need to keep them matched up.
 

For the stub axle - as Einspritz said - flip the nut to protect the shaft end and you can drive it out. I used a brass hammer and take care to drive it straight to protect the thread ends. The brass hammer will help protect too.

Thanks, I’m going to have the trailing arms and the rear subframe blasted so I didn’t want to leave bearings in. I did try using the nut on to tap it out I had a piece of scrap wood to protect it. I’ll try again tomorrow with a little more gusto

Yeah tapping ain't going to get it, it'll take a few good smacks.🔨.

None, after all the work you need to replace the bearings,  you've done all the work to get in there do it right. One and done back there.

I didn’t want to reuse them  just to be able to bring to the bearing shop and have them be identified.

what if you no longer have the shims? Can you order new ones from BMW?
