I had DW too the other day, turns out to be bad tires (wranglers). They balanced fine but under load they were out of round. At work we have a balance machine that also checks the road force so I fugured we check the newer dura-trax tires, one was slightly out of round so I put that one in the back. So I would suggest after getting your jeep back on the road swap rims and tires with someone that doesn't have DW and go for a spin. My front end guy has 30 years experience he did the alignment and took it out on the road and when he came back he said "get those tires off that jeep!" installed different ones, problem solved. I can still feel a slight wobble when I hit a weird bump on the road but it just goes away now instead of continuing on. Set my pressure @35psi.
