Never thought it would happen to me- no towing, mild off road, mostly highway. Noticed a vibration at 60+ coming up through steering wheel- reputable alignment shop in town diagnosed dead track bar and steering stabilizer. Stabilizer was aftermarket Skyjacker unit. They ordered NAPA track bar- he says he gets less complaints on those- put new spare up front and new LTX as well. Fronts had good tread left but one got pretty cut up on curb so I had to bite the bullet. All in all better but I guess I will establish a track bar fund. 34,000 miles- took delivery Dec 20th 2001- should definitely last longer. I think two or three violent death wobbles some time ago maybe started it going. I fixed that but damage was already done I guess.
