88 GMC TC front output flange

Torque specs for the pinion preload? Depends on whether you are just re-using existing bearings or if it is an overhaul using new bearings and crush sleeve. I cant remember off hand what the torque is for new. If I am just replacing a pinion seal for example, I always mark the location of the nut in relation to the shaft, count the number of threads (or turns of the nut) that are showing and try to get that nut back exactly the same place. I will check my book when I get home.
