Just an update...was experiencing the awful death wobble on my '10 JKU, and had no luck with a new steering stabilizer (should have looked here first, I know) and the dealership checking it out. But they did say according to the TSB, I should get new tires and an alignment —*my original Goodyears were pretty worn at 37,000+ city driving miles.
So, $800 later, I now have a new set of Firestone Destination A/Ts from Tire Rack and a new alignment — was told that the old tires were toeing in. (Tire tech also reported that everything in the suspension seemed fine and "tight.") And it's only been a couple days, but no sign of the death wobble on the highway.
So, crossed fingers, but I think this may have worked. Just figured anyone dealing with this may want to have this information.
