I have a question about the pinion preload torque spec. I've been using a book written by Jefferson Bryant. He states the pinion preload on Chevy 12 bolt should be 14-19 in lbs. Yet it seems the consensus of those who are experienced on this site that it is 25 inch lbs. My final reading was 16 inch lbs. Should I be concerned & if so what are the consequences of it being 16 inch lbs.
