Wheel Bearing; FSM Torque to Light or just Right.

[Ma son]

No typo.The IN.lbf is only a starting point. The goal is breakaway preload. When read "in that light", it becomes apparent, FSM means what it says!

A 50ft-lbf to achieve 12lb breakaway. Indicates new bearings, good grease, at ~68F.

It just seems crazy to me that as a starting point it is 40-50ftlbs from the final torque many of us, including yourself, are seeing to get the desired breakaway force on the adjustment nut. 38-57 ft•lbs seems to be a much more appropriate torque to achieve target breakaway force compared to those numbers in inch•lbs. Either way thanks for posting all your findings and numbers!

It is, a very light starting point. Which has resulted in many miss interpreting (using as goal).

I've found if torque comes in under 40ft-lbf with 12lb breakaway, indicates one of two things: Bad bearings or grease to cold.

Just did Koyo bearings. 47ft lbs yielded about 12 pounds break free resistance on a luggage scale. Mobil 1 synthetic for the bearings. For the hub bushings I used Mobil Mobilith SHC 460 (nlgi 1.5). I managed to get the driveshaft snap rings to no measurable clearance on one side and .002 on the other. Used a flat nail puller to pull out the shafts, as seen in the picture.

This thread was a MASSIVE help, thank you everyone, especially @2001LC

This whole debacle has left me pondering if these vehicles tend to be wheel bearing eaters because of improper pre-load after replacement. Maybe with a mixture of lift kits and larger tires that they all seem to have now. The ones I removed had cut grooves into the thrust washers.
