    What are the torque specs for the nuts that hold the spindle on and the torque for the spindle nuts.

    The spindle nut tightening sequence varies by the year of the truck. IIRC the nuts that hold the spindle on are 60 lb-ft, but I would get a book or wait until someone can double check it.

    65 ft/lbs tightened in several incremental stages in a criss-cross pattern. I usually do something like 30-50-65.

    [edit]
    Oh, on the spindle nuts... I don't recall the actual book values, but they vary from book to book anyway. I always do it like this. First nut on and snug. Spin rotor. Snug harder. Spin rotor... Repeat till you have to really put some muscle on it to tighten it any more. Spin rotor one more time. Back off nut a 1/4 turn or so, then tighten "firmly" (a bit more than snug, but not "tight"). Then put the lock washer thingy and outer nut in place.

    [edit again]
    Hmmm, I guess I should say that "put some muscle into it" is with a standard 1/2" drive (not a long breaker bar or cheater!) and I'm not talking about veins standing out in the neck either... Just tighten to where you *know* all the slack is gone. You can also sanity check by trying to wiggle the rotor, there should be no play.

    Torque inner adjuster nut to 50 ft/lbs to seat the bearings. Rotate the hub several times. Back of the inner nut 1/4 turn maximum. Install lock washer, turn inner nut to the closest hole in washer. Install outer nut to 50 ft/lb. Final bearing end play should be total of 0.001 to 0.010.

    Like I said, the exact proceedure varies considerably by the book. My factory service manual says:
    1) Tighten to 50 ft/lbs while rotating.
    2) Backoff and retighten while rotating
    2a) For auto hubs, retighten to 35 ft/lbs
    2b) For manual hubs, retighten to 50 ft/lbs
    3) Back off adjusting nut
    3a) For auto hubs, 3/8 turn max
    3b) For manual hubs, enough to free bearing
    4) Lock Ring
    5) Lock nut to 160 ft/lbs MINIMUM.
    6) Measure endplay 0.001 to 0.010 inches
