Road vibration - axle bearings?

I agree on that, it could be a bad U-joint or a loose U-joint, just check the drive shaft joints...
or you can test it parked, engine running, with brake pedal pressed all the way, changing gears from reverse to drive, and from drive to reverse, passing the neutral very quikly, do it for a few times, just don't let the vehicle move, If you hear a solid metal noise, you have a bad or loose U-joint an that can cause vibration at high speed. Hope it helps...

I don't mean fill the tire with liquid, just 8 liquid ozs, which comes out to be 12 ozs of weight (I weighed it).
Do some googling. It's a common practice in heavier tires. They make Dyna-Beads (a special sand) that does the same thing. The science of why it works is complicated, but it does work.

selkov<--- Just because you don't feel anything doesn't mean you have one that's bad. You have to first mark the shafts to there respective placement on the yolks then remove the saft and physically feel each bearing to determine the possible issue. Also check for any missing weights.
The front shaft could also be the issue as well as the CV (half shafts) joints.
Finally what about tire pressure? I used to run 38 psi in the front and 36 psi in the rear if I remember correctly.
