This thread started discussion about the death wobble 5/11/2016, additionally there are several other threads both here on IRV2 and other forums that have been discussing this issue for at least that long. There are HOURS and hours of reading available, this is not something new. There are variations in the symptoms, some folks have it happen at low speed, some high, some while turning, some while driving straight, but all are scared by it. There are even some folks that have towed a significant number of miles and not had it happen (including me, coast to coast several times). The problem has been reported in both the Cherokee and Grand Cherokee. The best thing you can do is your homework. By the way, I am told it is also happening with GM products that have EPS.
