    Just wondering what most of you use for a torque setting on your u-bolts? I have heard of wildly fluctuating numbers here, and I can't seem to find a definitive answer yet. Is it the 90 lbs someone told me, or all the way to 150lbs another person swears by? I think 150 would be excessive, but I did 100 last night after changing shims and it seemed like it might need a bit more? By the way, this was on the rear 14 bolt if that makes any difference (doubt it will) with quality Deaver made u-bolts...

    Whatever the value, always remember to retorque after initial 200 miles or so and/or after heavy wheeling.

    There is a Right way, a Wrong way, and then there is My way. The latter is usually the most fun! [​IMG]

    Well, I guess I will go with about 130 then. Anyone else have a number they always use?

    I think my factory manual says 140, but the lift kit did say 110, i usually go with the factory, unless i'm feeling weak.
