Death Wobble track bar, and an observation.
 
alright replaced original factory track bar bushing did not seem to be too much play, but figured i would start there.

did not stop Death Wobble. I did however learn that a BFH works well on the on the end of track bar:punk:

I did not change the bolt size...i read somewhere to go to a 7/16" bolt?

Is that necessary. the OEM has worked fine for thousands of jeeps.

Observation:

I have been researching about death wobble for a little while now, and I used to agree that one should not band aid fix death wobble with a steering stabilizer.

However, i was driving down the freeway and i saw a car with a bad shock. We have all seen them driving down the freeway where the wheels is bouncing up and down a gazillion times a second and it got me thinking that ... maybe a steering stabilizer is a major problem/factor with DW not just a band aid fix.

Can we surmise that a supposed well sorted jeep will not get death wobble with a bad stabilizer?

Love to hear some input on this because after seeing the blown shock car, I am started to think differently about the stabilzer being a band aid fix, and believing it is one of many key components in the elimination of DW.

Yep, a steering stabilizer will cover slightly for a death wobble. A properly set up jeep doesn't even need one. It's there to assist only, and to give your more feel for the steering wheel.

Ours does not DW. But I made sure everything was tight, no play in tie rods, ball joints, drag link, control arms, or the dreaded track bar. Also tires play a big roll in DW, irregularly worn or out of balance contributes to it.


As for the bigger bolt. Per Jerry B (Jeep God) swapping out the bolt for a higher grade 8 allows you to really crank down on it, instead of 45 ft pounds, you can crank it down to 60. I'll be doing it tomorrow on ours, just in case.

As for size, not sure on that, I did notice when I had ours apart, the bushing is larger then the stock bolt and questioned that. I guess we'll both wait to hear more on that.


Almost forgot, a bit about the DW and steering shocks, for maintenance only I replaced ours. Figured after 13 years/137000 miles on the original it was time.

WOW what a difference in steering feel. Before you could spin the wheel with a pinky.
Not now, now you have to turn the wheel with one hand. Made the jeep feel much more stable on the road. The old shock could be stood on end and it would collapse under it's own weight. So it wasn't doing anything.

The steering stabilizer can stop a minor vibe before it goes into a DW. That is a big deal. Some guys might say that you can run without one, but I NEVER would. Jeep put it there for a reason, to stop side to side oscillations, just like the little shock on a street bike's steering will stop a minor vibe from becoming a full blown tank slapper. I've had the DW when all the joints and track bar were perfectly tight. That one was due to alignment.

You might be on to something. How long does a SS last? I'm about to replace a Rancho SS under warranty.
