Posted in group BSJ FB page.. but I know a bunch of yall aren't in FB..
In March I had death wobble from loose parts. Tightened and problem solved.
In June I had wierd noise coming from wheels. I replaced both upper and lower ball joints, wheel bearings, and axel u joint. Problem solved.
In July, I got death wobble again. I noticed my steering stabilizer had a golf ball size dent at the bottom and thought maybe it busted a seal. Jeep sat in grease for a while.
In August, finally got the steering stabilizer replaced and it didn't solve the death wobble. The dented stabilizer still had resistance. So I replaced the tie rod ends and drag link. Now I have soft wobble.
I don't mind replacing parts as they are 8-11 years old and this isn't a pavement only jeep. I am just clueless as to what's causing it.

Could be the tires, you could rotate the back to the front and see if that helps. A friend of mine just went trough this on his LJ and replaced a bunch of parts and it ended up being the tires. Good luck

Also take a look at the control arm bushings and track bar bushings.

When I had it it was a little slop in the steering box

Something that is common is a loose track bar bolt that wears the joint enough to oval it out. That bolt needs to be wicked tight. I'm sure there's a torque spec, it's not in my head to say what it is.
The loose bolt turned out to be my problem that I found coming back from a Maine NEA meeting a few years ago. My introduction to Death Wobble coming home.

My frame mount hole wallowed out, no amount of torque could stop it from moving. I added the brace and welded the nut to it, it’s not moving now

Track bar ends where just replaced 3 days ago. Not the issue.

Good excuse to upgrade, you still win even if that’s not the problem

Yup my 'ol Jeep is starting to show its age. Had death wobble a month ago, tightened the bolts and fixed it. Now it has returned as a soft wobble. I'll try the tire rotation this weekend. But I'm wondering what a steering box upgrade looks like?

A new box fixed mine. I went with the PSC Big Box as it was a significant upgrade for not that much more. I did go with the upgraded pump too. Before the death wobble I was planning on going hydro assist but the new box and pump made a big enough improvement where I didn’t need to do hydro

Did you do the work Randy?? I've had Elias do my last steering box and never done one before. But would be willing to do a wrench day to learn

I did the box and pump myself. Not a big deal on a JK, not sure how a TJ is but shouldn’t be much different
