I did this with the help of two other members. And with air tools and the proper tools the job went alot faster. So you jack up your car, take wheel off, brake caliper off, rotor off, and the center nut (30mm). **there is a locking dust cap on the center nut which needs to be removed** After this remove the 6 hex bolts that hold the half shaft to the diff. Then you get to this pic where the hub is exposed and the axle stub in the hub is ready to be pounded out. ***I should also add that to ease the aide of this process on the drivers side, the exhaust should be dropped.

Halfshaft knocked out with a center punch. We were lucky it came out easily.

Knock hub out from behind with something about the size of the diameter of the hub and smaller than the diameter of the inner race of the wheel bearing

heres what you will be looking at, basically the splined shiny portion is the hub to be knocked out

Heres your wheel bearing. We were lucky again b/c the inner race did not stick on the hub. However I had bought a extra hub incase this happened. Turned out this saved us alot of time on the other side.

Then we have a pic of the $$$$tool set that makes this a 15min job

You basically fit a hollow diameter tube bigger than the outer race of the wheel bearing, and another behind the trailer arm. Two circular plates fit over the tubes and a big ass bolt goes through the center. a nut goes through the bolt. When you tighten the nut, the bearing gets pressed out toward you.

Bearing out!

Sorry crappy view from behind showing the holding plate that will draw the bearing back in.

New bearing in!

Installing locking circlip
(http://i25.photobucket.com/albums/c57/m42sport/rear%20wheel%20bearing/IMG_2429.jpg)
Installing hub. Same concept as before. Plate over hub to draw it into the wheel bearing, except this time the plate on the OPPOSITE side is only bigger than the INNER diameter of the wheel bearing.

Hub In

After this reinstall your rotor, calipers.
I replaced my half shafts with remanufactured ones while I was at it. When reinstalling the halfshafts, you can pound it in from the differential end, just make sure the splines on the hub and halfshaft are clean. Also make sure to put ANTISEIZE on the splines. It should go in fairly easily. Also make sure your pounding the shaft in straight into the hub. Then bolt the shaft up to the diff. Reinstall your exhaust and your done... There were some complications I should note that which I'll add later on.

Great write up! I'll be doing this soon on my e36. I bought the expensive wheel bearing tool so I hope everything goes smoothly.
Just curious, did you freeze the wheel bearing at all before installing? If not was there quite a bit of resistance in pressing it in?
Thanks!

OK....so where did you get the tool?

Pricey but it seems that the tool can be used on VW, Porsche and Mercedes too. :D

Good write up. You can get the tool from Harbor Freight for 60-70 bucks or so.

What? What's the part number? And have you actually used the HF tool in this application?
