that is what I am afraid of, a bent rim can cause some serious issues when hauling those weights... like braking welds and coming apart going down the road...
If you're shocks are worn, that could also be the issue. If the stiffness of your suspension starts to drop, it will change the natural frequency of the system and therefore change the rpm at which you will feel a lot of vibration. So if the tires and rims checkout okay, I'd immediately replace the shocks.

I agree. These trucks have a problem that begins when you change the angle of the rear diff. This causes the u-joints to be at different angle on the driveshaft (hence the vibration). Also, pull the shaft and check for a "dry" cup on any of the u-joints. (P.S. Did you have an empty box or a little weight on board?)

Looks FAST!!!!! 110 MPH even when it's parked (due to a stuck speedo)
it was empty, all it had on it was a soft cover that came on the truck...
but that all makes sense, I think I will just replace all of the suspension components and be done with it...that should do it...
ie: shocks, bushings, tires, rims, etc...
yeah, that's one way to do it. unfortunately, if it doesn't work, you spent a bunch of money and have no idea where to go from there. good luck.

I will do each one at a time to make sure that I can tell if I fix this particular problem, but I would be replacing most of this anyway, with 166k on the stock stuff, it is time for new all around anyway...IMO
