My old and new bearing were 2 different sizes ,meaning the honed out bearing gave a different backlash and pinion depth than the new one needed...........and it takes alot of torque to crush that sleeve...alot.

will this must be the wrong crush sleeve, i know from all the chysler `s i have done mostly 8 3/4`s , you use around 170ftlbs and the 8 1/4`s you end up with 120 ftlbs, if the prober drag i seen on the pinion at such low torque # then the bearings must be bottoming in the races before the sleeve is being loaded,i know if i put 300ftbls on this setup the pinion will bind the bearings and not move at all.

went thought the rear-end yesterday, everything looked good the backlash and the contact pattern, this being the first chevy rearend i have done i called a few local racer and got there thoughts, so i pulled it all apart , removed all the shims from pinion and placed a stock .036in shim under the new bearing when i install it you could feel that it was making contact on the crush sleeve it took 150ftlbs just to take the slack it the bearings, so i then used a breaker bar and got the 24inlbs it needed,when i install the ring carrier i had to move 2 thin shim from the right to the left , i couldn`t get the pattern on center front to back but it was close,the rearend is smooth and quiet now so it must have been the pinion was to deep even though the pattern looked good.
