    Hey, I think it is like torque to 50 lbs while rotating rotor (spindle), then back it off 90 degrees. Then torque to 35 lbs while rotation, then back off 3/8 degrees. I think this is for your year k5. Earlier ones are just a little different. The torque specs are on the adjusting nut. The lock nut to 80 lbs. I just checked this with the manual, and those are good numbers. LOL (luck not laughs)

    If you ain't hurt, you ain't playin' hard enough.

    I did mine that way and the 3/8 "backoff" seems to make the bearing have too much play. Could this be a typo? Was it a Haynes manual? 1/8 "backoff" produced what I deemed a more desireable play. Just didn't seem right when I back it off 3/8 turn!

    First "torque" seats the bearings and races.....second "torque" preloads the bearings.....I used new bearings and in fact the hub was also new. The only old part associated with the wheel bearings was the spindle. This leads me to believe that the 3/8 "back-off" (On the second torque) is a typo.

    Thanks for the help. I think I will try the 1/8 turn and see how it works out.

    K5ron,
    Just a quick lesson for me on preload. I read it all the time. I do it when working on bearings, but just how the %*(does it work in reference to preload. I get it in the diff, but not on reference front wheel bearings. What is it pre loading, the weight of vehcile, wheel, what. Sorry for the dumb question, but it is bothering me and I don't want to be an idiot when talkin this stuff. Thanks and have a laugh at my expense.
