    Have you measured your driveline angles? Sounds to me with the lift that you are just killin your joints then the 38s are taken em out.

    Which end are you breaking it more at? The axle u-joints, or the transfer case u-joints? Is it the front driveshaft or the rear?

    Yeah, your driveshaft angles are too steep. Another thing you could try is rotating the axle up, and that would require modifying the spring perches.

    is there any pads(shims) something like that i could use? My front axle has some shims that really change the angel.
