Well if someone tells me they have bump steer I'm not going to be arrogant enough to tell them it can only be specifically caused by one thing. I'm going to understand that they are describing what happens when they hit a bump and start the diagnosis from there. If someone tells you when they hit a bump their JK changes lanes, how would you describe it?
Whose drag link flip / track bar setup did you add? As suggested, are they at the same, or near same angle from the pitman arm to the knuckle, and frame to axle? Are the bushings & TREs OK? Teraflex's approach is a bit differnt, in that they drop the track bar mount at the frame rather than raise at the axle. Not ideal but works fine. (Drag link & track bar are in different planes.) Please advise and we'll see if we can sort this out.
Well because I didn't expect to get all these replies (thanks for that). I paid extra attention this morning when I was in my JK.
Hitting a bump with my left or right tire will cause a pretty severe shimmy in my steeringwheel. Approx. 1-2 inch turn in the steeringwheel.
When hitting a bump with both wheels simultaneously it also causes a shimmy, but when holding the steering wheel it's nearly noticeable, only when I let go of the steering wheel.
There is a corner in a road over here where I do my death wobble testing. Every time I hit the put hole in that corner (steering left, hitting with right tire) everything start to shimmy pretty bad. I'm sure when I remove my ss, death wobble will occur.
All my components were brandnew added two years ago. The flip kit and teraflex track bar were added a year later. Total miles on axles, lift kit etc. Max. 10.000.
