Okay, brought the drive shaft to a driveline shop and they don't see anything wrong. They said the hanger bearing is like new and the diveshaft is not out of balance. Four new tires, three new u-joints, new torque converter. Now remember from previous posts that you can fill it from about 35-50mph witjout a load and with my utility trailer from about 20-55 mph. What else can it be? I am on the verge of trading it in just to get rid of the problem. Please any help would be appreciated. Thanks for the help in advance.

Just wag here...Take alook at the balance weights on the rims....How many separate weights do you have on each rim...Out side & inside...

When I got my truck it rode TERRIBLE..I pulled the hub caps & took a look at the weights. I some places where they needed 3.5 oz, the installers had used 3-4 separate weights ,sread out over 4 or 5 inches.The correct proceedure would be (1) 3.5 oz weight, which they obviously did not have so they thought many would do the same thing. I took all the weights off untill I had a chance to balance them myself & the ride was remarkably improved with no weights. If you have bigger tires, you need to have them balanced at a place that is used to doing big tires....

Mine shook so bad the speedometer didn't work right....

Agreed...A lot of times Vibrations are caused simple by a tire thats not balanced correctly or a tire that has too much "road force." Actually went through this myself a couple years ago...Brand new 35" BFG A/Ts truck shook like a mo-fo between 60-70 mph. Had it balanced THREE times before it was right. Ended up have a place that knew what they were doing put a DYNAMIC balance on the wheels (weights on inside AND outside of wheel).
