    Would it be better to get a garage to do it or do it myself? I've done them before, but not on an M3 (is it any different??)

    What is the hub nit size?? It's Fookin Huge!!
    46mm is the nut size and your gonna need a thin walled socket. like a 12 point one or something.

    My rear hubs, bent my 3 arm puller's threaded part! Stubborn hubs!!! This should be fun!!!

    Colin,
    the wheel bearing in the pictures is the cheapest bearing GSF supplies (didn't want to buy an expensive one to try) and they have helt up quite good! As you know I am running R-compounds all the time and they bearings are still as good as new after a hard track day season. Not bad for 38 each.....

    Thanks Uwe. I was just trying to sus a knocking sound and put it down to the NSF bearing. I'm gonna try this as soon as I get some E28 hubs.

    cheers again!

    Thanks for the responses. I realize that you would need to match the teeth count to whatever the ABS computer is exectign to read.
    It would seem that more teeth would give a more precise figure to the ABS computer in it's ability to detect differences in wheel speed.
    For example, with 20 teeth you get one measurement for every 18 degrees of rotation, but with 45 teeth you a measurement every 8 degrees of rotation, etc.

    Hi Colin

    The e28 was already carving the German roads when the e30 M3 was in the design stage. There must be a reason why the BMW engineers changed the tooth count for the M3 ABS system, as otherwise, they may have just used an e28 hub. Why is lesser teeth more precise? I don't know but would be happy to hear it from the experts.

    I would think that the M3 ABS would be the target recipient for the finer resolution, not the E28. Or was it a question of the larger wheels worn by the E28 requiring better sensitivity to angular velocity?
    Also, has anybody tried to adapt the M3 to use the E28 system?

    I don't have any reason for asking other than simple curiousity.
    It doesn't work....you need the lower tooth count rings

    Great pictures, thank you! I've read this process described many times, but had never seen pics before. The overall pics of the hub before & after the ring swap really tell the story.

    Great point!!! The hot cold tricks for bearings makes things go together like butter... The wife used to always ask why I had car parts in the freezer!!!

    Cool. Yeah....I was thinking of doing that. I did new hubs last year so but kept the e28 rings on and disconnected the ABS. I am not a huge fan of ABS but ever since I have pulled the rings off of the old hubs, I have considered going back with the ABS.
