RE: 80 Trans. failure update...DOA

["Freed, David (Exchange)" <DFREED@bear.com>]

Thrust Washer failure is only due to incorrect clearances on the rebuild.
Driveshaft CV going bad would cause a vibration that might affect the
bearing's life but not the thrust washer.  I haven't done a Torsen Diff. but
I'm an automotive machinist that has done other brands of diferentials.
Install can't damage a thrust washer.  Take him to court if he doesn't stand
by his work!
