thanks for the responseWhen you change crush sleeve, and the pinion bearings and races you absolutely are changing 50% of the rear ended setup. Chances of returning the pinion to the exact distance it was from ring gear would be a long shot. Old bearings need pressed off or cut off, and save the shims under it as the starting point for new stuff. I bought a cheap set of new pinion bearings and grind with a carbide bit the inside races down smoothly where they will just slide on and off by hand. Then put pinion in without crush sleeve and tighten the nut with a beam style inch pound torque wrench to 15 pounds of rotational resistance-can only be a beam style torque wrench. The ring gear and carrier go back in and start checking gear pattern to determine amount of shims under pinion bearing. Last one I did probably had the pinion and carrier in and out 5 times getting pinion shimmed and depth into ring gear correct. Once that’s set take your “test fit bearings” off pinion leaving the shims and put the new bearing on and place in the press getting it into position.
IMO it’s best if you have someone with experience to guide you through the job. They do make pinion depth setup tools that are $200-$300 bucks then you can reference the numbers stamped into pinion to set proper depth that way. It’s the next tool on my list for sure. Check out Quick Performance they have the best deals on differential kit parts and tech tips, very nice people in Ames, Iowa.
would i also need to change the shims on left and right of the carrier or just the pinion depth shim(s
