Rigged up an old fashioned torque wrench to double check the pinion pre-load. I have a small inch-lb torque wrench but the numbers are so small it is easy to fool yourself. A weight on a lever is hard to fool.
The problem with that way is there is a break away amount that is more than the actual turning torque, with new bearings on a 60 I like 20 in lbs turning
As Strange says, Rotational drag The pinion nut needs to be torqued to 250 ft/lbs. With the pinion bearing properly lubricated, increase or decrease the shim stack under the front bearing cone to achieve 20-25 inch/lbs of rotational drag or pre-load. This adjustment is why we recommended polishing the area on the pinion where the bearing rests; it can greatly speed up this process if you don’t get it right the first, second, or even third time.
