Slop in the ball joints can allow both caster and camber changes, which can cause a shimmy. I'm not so sure a driveshaft u-joint will cause it, but it's not good regardless. Check to see how tight the rod ends are on the steering linkages and the track bar. An easy way to check is to have someone move the wheel back and forth without turning the tires too much. Any 4x4 Dodge owner knows all too well about the slack-on-center in the steering. Obviously, you need to lie on the ground in front of the truck, and it needs to be running, so do this with someone you trust. Make sure the steering damper isn't weak or blown, too.

If the guy at the tire shop is correct. You can diagnois this yourself by supporting the truck by it's rear axle. Thn remove the rear wheels and drums. Run it up to speed and note the vibration.
An out of round tires, bent rim, problem in the sidewall of a tire, tire can still be perfectly balanced.

1. rotate tires front to back, test drive and see if anything changes, if so change one side and narrow it down to which tire or rim is bad
2. if rotating doesn't change a thing then while driving put in neutral and see if anything changes, if so drivetrain ( if you can take it out of 4 wheel drive do it and see if anything changes )
3. also try touching brakes when shimmy starts and see if anything changes.
you just need to take one step at a time to naeeow it down
good luck!!
