    Actually, I broke my very first U-Joint on this truck.. I am so excited!!! I probably sound crazy though. I thought I killed the entire drive shaft.. but NOPE.. just a U-Joint..
    Anyway.. anybody got any good ideas about how to make them stronger... or a cheaper alternative.. or some kind of strengthening that can be done there??? The drive shaft is insanely strong.. but those U-joints are another story!
    Also, I would just like you guys to know that I ordered my 4" suspension lift and all new body mounts... including a 3" Body lift... I am so psyched!! I should have all of it by Wednesday.. which means the truck will be 7" taller on Saturday or Sunday at the latest!!! I am getting 37" tires in two weeks!! CANNOT WAIT!!! Appreciate it guys.. thanks for you help! /forums/images/icons/smile.gif

    about all you can do to get stronger joints is upgrade to 1 ton joints..but that would require a new shaft built with the correct yokes and a new yoke for the rear end /forums/images/icons/grin.gif

    The other thing you can do is make sure that all the u-joints are running at the smallest possible angularity possible.

    There is an interesting table that documented the "service life" of the various u-joints depending on the angle that they were operating at....if for some reason, you are running with the u-joints in a sort of "binding up" position, they will wear out in a hurry.

    If all the angles look reasonable, then the alternatives are to increase the SIZE of the u-joints, or "modify" your driving style to be more gentle on parts! /forums/images/icons/grin.gif

    it is good to have weak u-joints some times. your chain is only as strong as your weakest link... sometimes you need a weak link in an area easy to repair and get to.
    but yeah, 1 ton u-joints and axles all the way.

    the only down side to the drive line being the weak point is if ya do wipe out a u-joint...and the drive line falls to the ground ya run the chance of messin up the yokes on the drive line and then you wouldent be able to put a new u-joint in...

    I sort of agree. Its strangley reassuring to know what WILL brake!! and then you can plan for it!!
