    I have a Warn locking hub on a '78 10blt. my Chilton manual says the outer locking ring (wheel bearing) should be 50ft/lb. I just read in that Petersons Shop Guide that it should be 150ft/lb! That's a lot of difference!
    Anyone know what it should really be? :confused:
    Thanks :)

    I too have seen many differing specs. from a low of 50 to a high of 180.
    If you have the time try the lower #s and check it weekly.

    Good luck

    My manual says 150 also . I used a torque wrench before , but it was myold beam wrench that stopped at 140 and had no problems .

    And once when I loaned it out all I had was a breaker bar and and a 1/2 drive wrench , that got it tight enough . Last bearing pack after our wet winter trailride , it was still tight .

    The spec was around 50 ft/lbs. until they started using auto-locking hubs from the factory. Part of the auto-lock mechanism is keyed to a special plate that mounts between the inner and outer locking nuts, so I suspect that they raised the torque setting to 150 ft/lbs. to keep the hubs from causing the outer lock nut to work loose. :blush:

    It won't hurt to put some grunt into tightening the outer nut. Just be sure that you still have a little bit of endplay in the bearings after you tighten it. I can't recall the exact spec right now, but somewhere around .008 inch comes to mind. :confused:
