"I suspect that most spindle failures result from improper tensioning of the
wheel bearings. Yes, the castellated nut plays a part in that, but the GMC
is a bit different in the tensioning proceedure. Follow the Manual EXACTLY
and you will seldom have a problem. Use a torque wrench. You do have one,
don't you? While turning the drum by hand, torque the spindle nut to 25
foot pounds. Then, loosen the nut 1/2 turn. Using only your fingers,
tighten the nut until resistance is felt. Look and see if the cotter pin
hole in the spindle aligns with a slot in the nut. If it aligns, put a new
cotter pin through the nut and spindle and spread the end. If it DOES NOT
align, LOOSEN the nut until it aligns. Remember this. Hub and drum
assemblies expand when heated, spindles not as much. This takes up the
slack in the assembly. If you start out too tight, when the parts are at
normal operating temperature, you won't have enough clearance and, trust
me, bad stuff will happen, and sooner rather than later."
