lockiing hub torque Q?

[southernspeed]

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?
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.

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.
