Almost every time I hit 40 mph the car shakes very violently and I have to slow down to 30 mph to stop the wobble. I checked the suspension and everything looks snugged up and looks okay. What should I look for to get this figured out?
what is a dry steering test?Wheels and tires would be #1 culprit. How old are they? Are they worn? Last time they were balanced?
for suspension components you need to perform a “dry steering test” and pay close attention to the trackbar bushings.
With the tires on the ground and a helper doing quick repeated 10-2 steering wheel turns, you watch the steering system and look for unwanted slop/looseness where things are bolted together. Especially with the track bar.what is a dry steering test?
I took my Jeep to get my tires balanced and they said they could not do it because I run spacers on my Jeep?! They also said I am getting this wobble because my bushings in my control arms are shot. Would my control arms cause this wobble?With the tires on the ground and a helper doing quick repeated 10-2 steering wheel turns, you watch the steering system and look for unwanted slop/looseness where things are bolted together.

The usual trigger for Death Wobble or shimmies that are not as violent is an imperfectly balanced front tire. Something being loose like the track bar can easily turn a mild shimmy into violent Death Wobble.

I bought the Jeep 3 months ago and it already had the wheel and tire setup on. Not sure how thick the spacers are but tires are 33 in.The balance issue is because you need a better place to get your Jeep work done. I'd guess that the same thing applies to the control arm bushings. Someone will correct me if I'm wrong on that.
Answering a couple questions may help us help you.
How long have you had this TJ?
How long have you had the wheels and spacers and what size are both of them?
How long have you had this death wobble?
It's possible bad bushings could make it easier for DW to develop. But bad bushings never actually cause DW, they just let it develop more easily when it is triggered by something else... like imperfectly balanced tires.I took my Jeep to get my tires balanced and they said they could not do it because I run spacers on my Jeep?!
