Is it air ride?  If the pinion angles get screwed up because ride height has been changed, it can lead to vibrations.

Yes the differentials. Like was said by J Hanncock ,the bags too high or too low with cause the u joints to bind along with other issues and you'll have a vibration. I didn't really think of that because it's there loaded or unloaded.

Try dumping the air suspension while driving and see if that changes it. Do not drive very long with it flat.  Also, a bad U joint will cause that. I had that happen. Only way I found it was when I was putting the driveshaft back up I noticed the caps didn't turn freely. Didn't notice anything wrong when it was together and I shook the yoke.

Dayton wheels not put on true?    Disregard if it has buds.

Try jacking up a set of duals and rotating them. Could be out of round tyres, or tyres not on the bead properly. 

Had this happen on a ute but could in therory do the same in a truck.

We've had issues with vibration at 55 mph and king pins and bushings are wore.  Sometimes we can change front tires side to side and it goes away.

Thanks guys can only try these things, I did replace all of the UJ's and have just put on new ride height levers as suggested by J Hancock and adjusted as the others were bent...have a few more jobs on her and will let you know once I test drive her.

Hi Guys, it was the suspension ride height adjustment for the air bags so once it was adjusted as per the book was all good thanks

been looking at this post since my truck has a wobble also. have checked everything and signs go to BAD tire. Just got them a short time ago.

Had a bad bearing, so replaced. didn't fix, ride height good, no loose tie rods,.....

When I replaced the bearings, noticed that several studs would have to be replaced next time.

Question-Can I use a small impact hammer to drive studs out while still on truck?  or pull hub?

while it is normal for some to pound out studs in situ... it is considered bad practice by my profession as it does impart loadings on the bearings which can lead to premature failure... however, there are tools that use screw threads to re-re them and these are safe to use... if the studs are at the worn out point it is good practice to inspect the bearings and add a new seal.... in fact, a mini overhaul can then be done, s-cam bushings and slacks inspected.

see how I turned a 15 minute job into 2hrs...!!!  welcome to the repair industry..... LOL
