once you start crushing the sleeve then you take a torq. reading with a inch
pound torq. wrench the spec is 24 in.(the amount of torq. the pinion yake starts
to move)
once that is done then you will need a dummy bearing kit to get the shims
correct for the case/carrier bearings with a bac lash of .008to .012
then watch the pattern on the ring gear to see if rides in the middle of the
gear when it does with the baclash spec met then you have a quiet rear axle as
long as no one uses the center pumpkin to jack it up and distort the case
