Our last race of the season, the CSRG season finale at Thunderhill, didn't go
so
well. On the first warm-up session, my wife pulls into the paddock early
and
says the rear end is making a clunking sound. Turns out the pinion has
two
broken teeth. Not completely missing, each one lost about 1/3 of the
tooth.
I have a spare stock diff (FC85870) but the axle flanges don't
match. Looks like
my original diff (FC2669) was upgraded to 1500 bits with
larger flanges,
bearings, and 7/8" 20 spline shafts. The rear case must have
been changed also
to accommodate the larger bearings. I'm assuming all this
was done to fit the
detroit locker, and heavy duty axles. Suppose to be
Mother Mueller parts
according to the PO.
So I now have two winter projects -
fix the original diff and upgrade the spare
so it
fits.
Anyone familiar
with these changes?
Does the stock 4:11 crown and pinion 510005 work with the
Detroit locker?
Thanks,
Tim
