Agreed.. the Death Wobble is not something anyone should toy with.. We've suffered with our first DW last summer while traveling to Colorado and back.. At 60 mph, we hit a rough section of highway sending the front end into a volatile shake. Afterwhich, and over the last few months we've been systematically replacing components and having the jeep checked out.
Personally, I think one of the best things we did to our 08 was upgrade the bolts on the control arms and trackbar.. Then upgrading the steering stabilizer.. Although the 08 is a different puppy that yours, it still suffered the DW on a stock (non lifted, Non larger tires)
