    I am repacking my front wheel bearing on my 1990 blazer. I was needing to know what to torque the lock nut at.I have auto locking hubs. Would someone know off hand? I think it is 50 pounds then back off to 35 pounds if anyone knows for sure please let me know. thanks

    i dont know about the torque specs, but i can say to ditch the auto hubs. not real expensive, easy swap, and the gains are awesome.

    you are describing the ADJUSTMENT NUT proceedures... the lock nut on my 78 is 80 ft/lbs,,, my books don't go up to 90, so I'm not sure what your specs are....
    But if you're really asking what the adj nut specs are,, yes,, it's 50 lbs,, then back it off 90 degrees,, then torque to 35 lbs, then back it off 3/8 of a turn... again this is on my 78,, just did them yesterday,,

    My manuel just described what Todd told you. Ididnt really like all this torque then back off stuff, so I called 4 wheel parts wholesalers and talked to a tech there. He said the standard practice is was 8-10 lbs on the inner nut and 50 on the outer. I have auto hubs and a '79, hope this helps.
