I'd be looking at other issues like an imperfectly balanced tire, loose track bar mount, etc.
Thanks Jerry and T2000J!
I'm trying to take it one step at a time. I had the tires balanced to see if that would help and the tire guys said the tires were really bad. The worst needed 6 oz. on one side to balance it. They put the best two on the front. It helped a little bit, but the wobble starts at about 56 mph, every time, and gets worse as I go faster, so for now, I keep to the right and go my 1 mph over the minimum speed limit for the few miles I go on the expressway here and there.
Trackbar, ball joints, TRE's, and steering box bolts all seem tight. Not sure about the steering box internals - there seems to be some play in there.
I think my next step will be new wheels and tires, but I figured if that didn't work, I would try to play with the caster angle a little bit to see how it changed the feel.
I talked with a former Jeep engineer and he said "go back to stock sizes" and that larger and heavier tires and heavier wheels that I am planning to get are going to probably make it worse...I figure there are plenty of Jeep owners with larger, heavier wheels that don't have DW, so I can figure this out!
