    Rear differential bushing replacement

    Today CoolZ4 (aka the owner of the highest mileage Z4... We're talking past 200K) came over to my place to get the rear differential busing replaced. It teared apart, just like the E46 does... Common problem, but lets not forget we're talking about a 200K+ miles car, so don't get scared...

    Anyway, the procedure is quite involving and requires removing the differential... And to get to it there's a bunch of other bolts to remove... I thought you could drop it without removing the diff, but no, there's not enough room.

    Here's some pix of the rear subframe without the diff:









    To pull out the bushing the special tool is a MUST... No way you can get that thing out without and with it... Piece of cake. CoolZ4 bought it from Baum Tools.





    And here how you use it to pull the old bushing out:



    Pushing the new one in is similar.

    Here's how the old bushing compares to the new one:





    And here's how the tech (aka me) looks like after the job is done:



    I've never got so dirty before...

    Anyway, CoolZ4 got quoted 6 hrs by a mechanic, I managed to do it in a little over 6.5 hrs.

    I wonder if the fact that I had mine replaced under warranty at about 15000 is an indication of the way mine is driven.
