This weekend was a fun weekend. Spend a sat pulling the diff out, i was able to do it without affecting any suspension alignment bolts, and without having to drop the exhaust.. Fun
Sunday i pulled the old diff out, and began installing the wavetrac. I was going to do a whole writeup, but burried in this thread was this link
http://mbworld.org/forums/w211-amg/2...e-install.html The install for the crossfire is 99% exacty the same.
I measured the stock backlash on the crossfire and it was 0.0045" (0.1143mm) after the wavetrac was installed it was 0.0055" (0.1397mm) all is good!

well within the 0.10-0.16mm spec mentioned
Today i spent some time reinstalling it back into the car, i should have it all buttoned up soon, cant wait to try it out
