I have a first gen lightning that developed a really bad wobble over a decade ago. I have taken it to at least a dozen shops/mechanics and none of them have ever figured it out. I really love my truck and do not want to get rid of it, so I hope you can help me. I know you guys get this all the time, but if you need a project vehicle you can use mine.

Radius arm bushing bushings replaced with poly bushing ?  Do you have taller tire's in rear ? If taller tire it can change caster angel . Steering box lose on frame or frame has cracks in that area

Thank you, I think I have switched out the bushings. The tires are the same size. I will check the steering box and frame.
