    Anybody know the torque on the lug nuts. 2500HD if that matters. Thanks

    I just found a previous thread that stated 140ft pounds. I'll go with that.

    Ok I will ask the simple question. How long a wrench to get 140#ft of torque on the lug nuts.

    It isn't that hard. My wrench happens to be about 2.5' It is just a firm pull. Would probably be hard with a 1' long ratchet. With the truck completely on the ground, the tires slipped a little in the process of torquing.

    Try to stay with-in 140-150 ft lbs. Without enough TQ the lugnut can warble and ruin your rim. However, too much TQ can warp your rotors, after a few heat cycles. Wheel studs can "pop" or "snap off" under a heavy load or wicked power. Just get a TQ wrench and wring'em up to just over 140lbs and you'll be fine. A good TQ wrench will probably outlast many trucks.
    -------- remember to always "reset" you wrench to "0"lbs before you stow it away.

    Torque wrenches are inexpensive now days. If you are going to rotate your tires they will pay for themselves. Later! Frank

    burner -that sounds like the problem i had with lug bolts breaking, two of them have broke twoo diff occasions. how much torque is to much- used breaker bar and gave them a slight pull because had to use thin wall socket to get to the nuts

    If you're lucky enough to have an air compressor and an impact wrench you can buy one of them torque sticks made to stop when 140lbs are applied to the lug (costs less than $20). I've confirmed the torque stick 140lb torque with my trusty torque wrench and its pretty much on the money. Also can't hurt to put a little anti seize lubricant on the threads (silver stuff) so you don't brake the studs if they get rusted on.

    Anti-sieze will make a difference. Lubricated bolts will tighten up easier, and you will over-stretch the bolt if you use Dry Bolt Torque Specs. The lug nut torque of 140 Ft-lbs is for a dry bolt.
    Looking through general tables with torque specs, it seems common for the torque for lubricated bolts to be about 20% less than for dry bolts. I said ABOUT, and that's the general rule I follow.
    These aren't head bolts were talking about here, so I don't consider lug bolts that critical.
