    Drop the air out of your airbags when it starts doing it, just for a few seconds and see if that helps. Maybe a faulty leveling valve. Even if new, they are junk any more IMHO

    Got under the truck today and the carrier bearing has a lot of play in it. Going to have my mechanic order a new one up and replace them it. Should I do u joints as well while its apart no idea how old they are?

    Yes do that, the U-joint kits come with caps and bolts.

    Glad you were able to locate some of the issue. Hopefully it's just confined to the carrier bearing.

    Make sure your driveshaft slip is greaseable. I just replaced all u joints, carrier and driveshaft. it solved most of it. Had to replace all my drives and steers because the damage was already done to them from shaking down the road.

    Ya my tires are all new with in the last 10,000 miles and show no uneven wear cupping ect. Ya I think that's what's causing it because it's intermittent and speed variable.
