    The thread that keeps on giving. Decided to try this myself and while not sure how folks do it trackside with no Dremel, here are my ads. I could not find a 46mm socket anywhere locally, now I know why places that sell the bearings offer them with sale for ~$50!
    I said what the hell and ordered Harborfreights huge 3/4 drive set with 2 drivers and extensions as well as 20 sockets I may never use again ~$50.

    Since I was there I also ordered their 3 size puller set for another~$15. I took the bearing to Lowes to see what I could use to pull against and found this flange.

    The board write ups are great, pulling one ABS ring was 15 seconds, the other a bit tougher but a touch of heat and it was off.

    A bit of finess with a bench vise and back on they went. I found that plaing the ABD ring top of the shoulder ~even with the bearing housing surface was pretty spot on, just as UWE shows in the first of this thread. Neither hub plulled out "easily" as some have stated so I used the gear puller and they came right off. I had a time with the remaining race that did not pull off. I had to work the Dremel a good 10 minutes on each but both gave it up. Not one to put many car parts in the fridge I just iced the spindle for 10 minutes and baked the bearing @ 150 for the same time.

    A light coat of oil one the spindle and the first side was a job, Many wacks with a small dead blow and the 36mm from the above mentioned set and it seated, the other side was 2 blows to start and the 3rd blow ran it the rest of the way.

    Is there any difference between the E28 cap listed above by Lee and the one that originally came on the M3 - 31211126065 shown here

    The one they list for e30 M3 is the for the e28 which means you will have to swap over your abs wheel from your old hubs.

    Either way, they re-list the e28 hub as the e30 m3 hub or it's really the e30 m3 hub for our cars and both has the same price?

    Yes, TMS = Turner Motorsport.
    They have all the parts except the rear cap. They told me people usually don't need a new one, so I guess that is why they don't carry it. Fortunately I did not need it.

    TMS is Turner Motorsport - http://www.turnermotorsport.com/

    The rear cap may be rusted out or bent.
    The front nut must be notched to keep from unthreading. The rear cap is optional.

    I recently bought mine from TMS. They seemed to have the best price. They sell the FAGs.

    No, I don't. But most aftermarket suppliers will want to know the BMW part #. Also, I later added the FAG part #.

    I always bring in my track toolbox a spare bearing with the ABS ring already removed.

    no I don't have any P/N. Just went to my local parts place and told them BMW E28. Any model but must have ABS.
    Or send a mail to www.c3bmw.co.uk

    Changed my bearing yesterday with E28 M5 bearing, pretty easy job if you have the tools.

    Made a short video comparing the noise before and after. Available at: http://www.bemarim3ex.com/index.php?...263&Itemid=201
