Offline As John suggests, or:
Bad track bar bushing.
Play in either the upper or lower track bar mounts
Play in the lower drag link bushing.
Improper drag link/track bar angle (both need to be close to parallel).

Offline Also, control arm bushings/joints, pitman arm, tire balance, etc. But it is NEVER a steering stabilizer issue.

Shocks are also a contributor if they have some healthy mileage on them.
Alignment? Toe-in can also be contributor seeing as how you replaced balljoints and tierods.
If there was no lift, then caster should not have changed, right?

Offline It's all been said already, but I'd look at the track bar, toe-in and caster, in that order.

Offline As we both have the same front end, remove the front DL at some point as well just to eliminate the possibility.
Also, as you might expect, DW is cumulative so any little bit in any or all of the afore mentioned possibilities can add up.

Offline ordered trak bar bushing this morning
the lift is maybe 2 years old (3max)
this vehicle has been off road a handful of times
how do i check caster(is that the after market kit they installed to do allignment)
also this vehicle was pretty much a spare til last year so it did alot of just sitting
dont even think the kid started it til i went to get it
no issues with 31s or 33s
if i cant figure this out 4wheel said they go over for 95$(im thinkin this mite be worth while to do anyway)
they seem pretty good any down falls with using them has anybody had

Offline Check this out. To adjust you lengthen or shorten the control arms.

Offline 4 wheel parts is great and a lot of guys use them. They practically built brads jeep. An alignment will help adjust the caster. Caster is hard to explain. I recommend googling it.
Um...what?

You might check http://www.jeepforum.com/forum/f9/. Caster has been discussed quite a bit over there.

If you have adjustable control arms an alignment shop may make the adjustments. Best bet would be an alignment shop that has experience with lifted 4x4's though. I don't know if 4 Wheel Parts does alignments but if not they may be able to recommend a shop.

I realize your going to hear just about everything that causes death wobble but positive caster has to be excessive like in the 9 to 10 degree range to even come close to causing death wobbles. That would mean the pinion would be probably pointing down hill. It is changed either with eccentric ball joints or if your control arms are adjustable it can be done with them. I would seriously look at tire balance and make sure everything on the front end is tight. Worst case you can add a steering stabilizer, it is a bit of a bandaid but quite a few 4x4's come with them stock. Mark

Offline Have someone sit in the driver seat and turn the wheel back and forth with the engine off. You need to get under the front and look at every component of the steering, pitman arm, drag link, tie rod, track bar, etc. look for any movement at all. The slightest movement in any of these components can cause death.

This is how I figured out my last case of death wobble...

I have been fighting death wobble issues for a while and I believe this is absolutely the first step. I am not an expert but have learned a bunch in the process. The planman video below on this subject is a must see. I would comment that some times people mix death wobble with shimmies. Death wobble occurs when you are driving and hit a bump or pothole that induces the steering wheel to go back and forth, some times violently. If you get a "wobble" that occurs at various speeds, regardless of the road surface, this is likely a problem with tires or wheels.
My JK is doing much better with a better track bar and tie rod. I believe the last issue to address is a bad ball joint on the driver side.

Offline every thing is tight and most of it is replaced for 35s
however i toed out the drivers side tire about 1/2 inch and no wobble
i cant drive like that as i dont want to waste my tires
ill be picking up trak bar bushing after 10am
i dont know if its both tires as i dont want to take a chance of losing Kayla out the side (although somedays 🙄 )
but the driver side is like the grocery cart wobble big time
think wen i get a chance ill see how 4wheel is 1st hand
they said theyd inspect for 95$
