Ok, So a small noise in the rear end has led to this. Both axel's along with bearing's replaced. Then pinion started sounding increasingly angry! So new inner/outer bearing's and race's. Also have new crush sleeve and nut. My question do I have to crush a new sleeve or is the old one usable? Can you use a regular "click" style torque wrench to get pinion load? With new bearing's and race's that should be 15-30 in/lbs correct? If using new crush sleeve is there an initial torque setting to start with before setting for the load? Any help would be greatly appreciate!
