I'm brand new here. I have a 2011 Rubicon (36,000 miles) with the "death wobble". I've researched it plenty and what the causes are. As my car is in Southern Belize with no jeep support here, I'm going to go for the fix myself.
I've ordered 4 tie rod ends (all) sloppy loose at joints, track bar, and steering damper.
I had a broken drag link on the stabilizer bar and fixed it temporarily. My question so far is: New drag links ordered from Rock Auto (Moog), are 4 inches shorter than the originals. These will lower the rear of the stabilizer bar...comments if this is ok or should I go with original? My dilemma: they were about 20 bucks, but shipping and duties to Central America was over a hundred bucks. Ahhh, the retired life!
Let's take things one at a time:
1. 4 tie rod ends? Are you running the stock tie rod or an aftermarket? And why 4??
2. Its unlikely the track bar was worn out, but possible. More important, IMO is the ovaling of the hole in the frame side bracket. Synergy makes a bracket that goes over the stock bracket that resolves any current issues and prevents future ones. (Its a very common source of DW.)
3. The steering damper has little to no bearing in resolving this issue.
4. You had a broken END link on the stabilizer bar. How are the originals 4" too short? Are you running a lift kit?? And no, you can't use end links that are 4" too short.
5. Don't overlook the possibility of tire issues causing DW. If you tires are out of balance, balanced but out of round, have internal cord separation - any of those can easily cause DW. You should have your tires road force balanced with weights on both the inside of the wheel and tape on weights as far out as possible. This is what is know as a dynamic balance and will minimize balance issues. Many a DW problem has been solved with proper tire balancing.
6. Retired in Belize..............how sorry are we supposed to feel for you??
