CJ Death Wobble

I was wondering about death wobble. Does the tie rod or the drag link bend causing the wobble? I watched my front tires when it started, and they turned back and forth fast. Anyone know how to stop it? Will strongerrods help?

Re: CJ Death Wobble

I had the same problem and found that the steering box was loose on its mountings. I tightened up the mounts and the wobble went away. The easiest way to check it is to start the motor and have someone inside the jeep rock the steering wheel back and forth while you check out the front end. It anything is loose, you should be able to see it. Good luck.

Re: CJ Death Wobble

A couple years ago I replaced the steering box mounts and added a steering box brace.
I guess I should recheck the bolts though. Good tip.

Anyother thoughts?

Re: CJ Death Wobble

there are several things that ca cause death wobble...
1. loose steering box... sounds like you have that licked..
2. bad caster angle.. if you dont have longer shackles.. not usually a problem
3. bad tie rod ends
4. bad ball joints.
5. bad steering stabilizer
6. unequal tire pressure
7. unbalanced tires

usually its a combination of several of these things...

Re: CJ Death Wobble

I get that "death wobble" too on my full size 95 ram with dana 60's when I run my 38.5 thornbirds or my 42" tsl's but not with my old 35 bf at's, I guess mine is balance related escepially the thornbirds wobble, hard to balance but soon will add the bags of equal to balance the bad one.

As for caster, what is it actually? Is it the angle of the axle?

Re: CJ Death Wobble

Dont forget excessive play in the rag joint or the slip joint of the intermediate shaft. Pretty much any play in any of the steering linkage components can cause it.

Re: CJ Death Wobble

I have a SRS, 35" MTR's (new and balanced), new borgesen shaft, and the tierod ends seemed good. Nothing seems to be falling apart, but the "wobble" feels like every bost is going to come flying out!

Re: CJ Death Wobble

Low air pressure can also cause the problem

Re: CJ Death Wobble

Is there any freeplay in the steering wheel at all? What I mean is, while running, can you feel any movement in the steering wheel that is not resulting in movement of the tires? Even 1/2" slop can lead to problems. If so, find this first. How about your ball joints? Are they tight? Spring and shackle bushings? any excess play there?

Re: CJ Death Wobble

Mine was caused by more than one thing, but mostly the steering box was very worn. I checked the steering with the engine running. Barely turn the steering wheel and the tires moved. Seemed okay. I didn't find the problem until I tried turning the steering wheel with the engine off. I could turn the steering wheel almost a quarter turn before the wheels started to move. I replaced the steering box and the upper steering shaft bearing. Solved my wobble problem
