    everyone always forgets to balance the drive tires.if you do,it will probably solve a multitude of issues. that shaking you are describing is a harmonic imbalance.everything on the truck that turns should be synconized,if something is out of balance enough....that's what you get.you could have 1 tire that isn't jiving with the others or a carrier bearing about to go. I would start by balancing all the tires(even if you have centamatics)

    Still have not found the cause. New tires (all balanced), three axle alignment, replaced tie-rod ends, king pins, they said all the bushings are good. checked u-joints and carrier bearings. Replaced all shocks in the begining of this. I don't really feel it in the steering, it is more of a bouncing in the drives. It will bounce for a couple of seconds then quit then bounce and quit etc. etc. etc. Have all but almost given up on trying to find the cause.
    Thanks for all the replys, except for the one stay under 70 that's no fun. 70 MPH speed limit. I try not to do more than 5 over but when passing I try not to take 5 miles to do it because I can :biggrin_255:

    Believe it or not if the trailer tires have flat or bad spots it will also cause this.

    K&N hauler Have you checked the ride height and the ride height valve to be sure everything is as it should be?

    Balance bead packs inside the tires. They work.

    Trailer tires are wearing good, no flat spots or cupping.

    Might have to try them, but really don't think it's the tires because the shake comes and goes. I would think if it was the tires it would be constant.
