Hub Bearing Torque Specs
Got a '95 F-350 4x4 and I need the torque specs for the front hub bearings. A general procedure would be nice too. We're rebuilding the hubs and I'm kind of in a bind and I would appreciate a little help. I'm a SD guy so the OBS trucks are a bit new to me. I'm loving every minute of it, though. Thanks, guys!

For manual hubs:
Torque the inner nut to about 50 ft-lb while spinning the hub back and forth to seat the bearings; then back it off 1/4 turn. Adjust the inner nut as necessary to fit the dowel pin into the lock ring. Then the outter nut is torqued to around 120-150 ft-lb.
Auto hubs are basically the same but with a locking pin that slides between the nut and the spindle and no outer nut.
