Front Wheel Bearing Torque
'97 F-150 2WD.
Book says 12lbs then 30lbs while rotating etc.
?-Do U torque to 30lbs and then back off a 1/16" or one flat spot on the nut.
OR
Do U just leave it @ 30lbs and call it good.
The book doesn't say, just wanting field experience. I know it's not a Jeep but on my CJ we (CJ owners) have found it is best to back it off a 1/16" or the flat spot on the nut.
Thanks,
Jim
P.S. ALSO-do you re-torque after you drive the vehicle for say 50miles. I have found after installing new bearings/races that after the grease works it's self out some (so to speak) that the bearing/wheel is a little loose (6-12 O'clock position) even after setting the race fully.

you want the bearing it be about a thousandth loose aginst the race so it dont gall. fill hte gap with grease. i have never used a torque wrench, but you got the idea. probalby 30 ft pounds would seat the bearing in the race, then back off one flat. should turn easy , and you should nt have any excess clearance if you try to wiggle the hub. dont matter if its a Jeep or Ford, all the same.

Thanks Steve, I can't seem to figure out why they get loose and I do it as U describe. I did seat the race fully but maybe the cheap Mexican metal,,,,,Hum. I did use one from China and had the same problem.
I bought them from A-Zone and NAPA. Couldn't find Temkin bearings.
Oh well, I'll check'em again before the kids go to college in Bama.

What I have always done is seat the bearing while rolling the hub, back it off 1/4 turn and then tighten the nut by twisting the socket by hand. In less you are a gorilla it will be about right. If the cotter pin does not line up back the nut off until it lines up. It is always better to be too loose than too tight.
