    My lock nut for my front wheel bearing is loose. What should be the torque on that? I thought my auto hubs were giving me grief so I bought some warn premiums. Guess I didn't need them but they are going in anyhow!

    Uh, is there a zero missing somewhere? 120 sounds a lot closer to the real deal than 12.! [​IMG]

    Which one? Is it 120 ft lbs? or 120 inch lbs. They were both loose. Do I need to retighten them tighter?

    First, tighten the first nut against the bearing at 50 ft lbs while turning the wheel. Back off a 1/4 turn and tighten to 35 ft lbs. Then back off 3/8 of a turn. Then put the locknut on at 160 - 205 ft. lbs. Of course you need the special 4 pronged socket to do this. I hope this helps.

    Yes, do like the BlueBlazer guy said. I can never for some reason, get it to 160 to 185lb torque for the life of me, but I just get it as tight as possible. (this is the outer lock nut). For the inner one, do the steps like BlueBlazer said.

    yep, 35 for the inner and 80+ for the outer. The haynes manual is a bit tricky when it envolves multiple models. I've had mine at the above setting for a few months now and no problems.

    Will work for beer, parts and tools.
