I had my dealership install the steersmart yeti frame side track bar reinforcement bracket when they replace my steering box. They did it for no charge. And it seems to stop my death wobble issue. Order it from Northridge 170$ it could help you
This does not seems fair. I too have purchase my Jeep from Koons after trying to negotiate a fair price from my local dealer. And if I have any issues with my JEEP I would hope my local would help me. What is the name of the dealership ?
