Help! Death Wobble!

My '06 TJ is experiencing some TERRIFYINGLY bad death wobble, to the point I'm afraid of losing a tire. I'm aware its a common problem with Jeeps (I have had it before myself), but was under the assumption that it means I need to change my steering damper (steering stabilizer). Well I did that, and it appeared the make it worse. At the very least, it didn't fix the issue. What other things could be causing this?

Of note, my old steering damper was a larger Rough Country stabilizer, this new damper is much smaller and I bought it at Autozone. I wasn't sure if the smaller/stock damper wasn't enough for my 33X11.5 tires?

Any advice greatly appreciated.

Disclaimer: I'm in no way a Jeep expert, but I've done a lot of reading!

The steering stabilizer is absolutely the last thing you want to change. It acts as a bandaid and has no true affect on the cause of DW, which can be a number of components, or a sum of those components. Here's some resources to check out...

Good luck!

Replacing the steering stabilizer is NEVER the cure for Death Wobble. While replacing it may temporarily mask the symptoms of DW, it's not actually fixing the true root cause of the DW. Installing a new steering stabilizer to cure Death Wobble is like placing a band-aid over a skin cancer & hoping it will be cured. Both only mask the true problem.

DW is normally caused by a combination of two things... a triggering event and something being loose enough to allow that triggering event to set the front-end into oscillation which when it fully develops, becomes full-blown Death Wobble.

One of the more common combinations that causes DW is an imperfectly balanced front tire serving as the trigger, with a track bar that isn't quite tight enough to hold the axle under control enough after the trigger. I haven't had DW in 15-16 years but that combination is exactly what caused mine. There are of course other combinations that can cause DW too.

I just fixed mine too. Track bar. Did you perform a dry steering test? Basically, grab a friend and have them engage the steering left to right WITHOUT the jeep running. Watch all of your front suspension and steering. Look for any loose bolts/joints/etc.....In my case, my axle end of my TB was moving about 1/2" with each cycle.

EDIT- in relation to your stabilizer....the PO of my rig had installed dual stabilizers that I erroneously thought were a good thing. They just mask the problem. When I replaced my TB, I removed the 2nd SS, and I rely only on the OEM one now. No problems.
