Right, I purchased a 4 door 2007 JK unlimited Sahara back in June 2018, it had a 4 inch lift (old man emu kit) and 20inch jeep tires (275/55/R20 Cooper Leon LTZ all terrain tires), i drove over 8000km, it was great. Then in March 2019 I hit a pothole at 110kmh. I got what I know now as the death wobble, believe me I thought I was going to die, I gently slowed down and it’s stopped at 70kmh, but everytime I went over 80kmh and hit anything uneven the death wobble came back so I drove it to the garage below 70kmh. The garage showed me the tie road damaged (longer part) so I got it changed it to mopar one and vehicle tracked, the death wobble carried on happening over 80kmh. So I took it back and he was unable to find anything and was advised to balance the tires which I did but again carried on doing it. So I purchased the Wrangler trackbar and lower control bolt upgrade kit and got the bolts changed, that didn’t work. So I purchased a Rancho front and rear adjustable trackbars and mopar steering tie rod end (shorter part ), I got them all fitted, vehicle tracked and wheels balanced at a different garage and they checked the wheel bearing and ball joints and was told they are fine. So yesterday I was driving after all the parts were fitted thinking yeah my jeep is fixed, then I felt slight wobbles doing 80kmh steady (cruise control), i accelerate and And go to 110+kmh and everything is nice and as it should be, I hit a few uneven surfaces and no issues, then after about two hours and doing 110kmh I hit a bad uneven patch on the motorway and the death wobble happened, vehicle shaking violently as before. I slowed it down to 70kmh and it stopped then carried on again feeing slightly wobbles at 80kmh until I got home. I’m going on a driving holiday covering over 3000km in two weeks and now I don’t feel confident taking my jeep, although the death wobble doesn’t happen as often as it did the problem is still there, I’ve spend over $1500 and feel that I got no where, I love my jeep but I think maybe it’s time I sold it if I can’t get it fixed. Any advise will be great, I’m from the UK so not many jee wranglers around or mechanics that know about the problem.
