My wife has a 2005 Wrangler sport that has been to the dealership twice for a shimmy (ie death wobble) at 55 MPH, both times the dealership has said the alignment was fine and they found no issues, they rotated the tires and the problem goes away for a couple of months, only to return, now it is doing it again less than 5000 miles form the last time and has pretty much destroyed a set of brand new Pro Comp AT's, I am sick of taking it to the dealership and getting no results, do any of you guys have any idea of what could be causing the shimmy ? Also the jeep stalled on I-40 yesterday at 70 MPH, first time that has happened
