I have been fighting death wobble off and on for over a year.
I have tried all the suggestions from here.
Rplaced all 4 ball joints, 2 were toast, and both hubs/unit bearings, one was bad.
Yesterday at our club's wrenchfest we measured my caster angles.
Taking into account a margin of error for the floor, we got 4.5 degrees on driver's side and 7.1 on the pass side.
Even with a margin for error that is WAY too much difference.
We checked my upper control arms and equal threads were showing.
i have a TeraFlex 2 1/2" coil lift, JKS adj track bar, and Clayton UCAs, 33s.

My plan is to get it to an alignment shop familiar with lifted jeeps and have them run the numbers and see what they get.

My feeling is that the axle tube is tweaked, probably from the factory, and the Cs are not located correctly.
My "worst case scenerio" would be to bring it back to stock, I saved all the parts, and try for warranty on a new axle housing. I have 27k miles on it right now.

Any other suggestions?

 

If you used an angle finder to measure caster, that's probably the whole problem. Angle finders cannot measure caster, since it is actually an arc. The only to way to get a measurement on caster is with a bonefide alignment machine, or a manual caster gauge. According to those measurements, it should be pulling HARD to the driver's side. Is it? If not, then I suspect those "caster" angles are not correct.

 

Your maybe bent causing the numbers to be that far off, and or where you measured may not be machined good enough and causing it to be off, i'm with rob on this though, you'd be pulling really hard if you were that far off. Get it to a machine, only way to know for sure.

 

Thanks guys, that's kinda what I was figuring.
It needs to go on a machine to be sure/accurate.
And, no pull to either side when driving.

 

no machined area on knuckles. so dont even try the angle finder. go to a aligment shop that deals with 4x4s.

 

Thats what I was gettin at.

 

I'll second the angle finder not being totally correct. I set my caster with an angle finder to 8* driver side and 8.5* passenger. When I had an alignment done the next day, they told me it was at 6* driver side and 6.1* passenger.

 

Went to alignment shop today.
Numbers on their rack showed 3.9 and 4.1
So I am relieved to see the tubes are not twisted.

 

The angle finder method is bull crap. The knuckels are forgings which generally to not match at all. That is why they machine the openings and all working surfaces.
