Tire Slime = Death Wobble?
Hello all.
My 08 unlimited Rubi has a nominal case of the dee dub's (death wobble).
I've broken the trackbar bracket off twice, both times was a limp home with a tie strap holding my TB in place with very nasty DW. So yes I know what DW is. When I say a nominal case of the DW, I mean, it only happens at very low speed and when starting from a stop and I hit a bump. The same bumps or worse are no problem at higher speeds, even on corners. I got under my rig last night and tightened the trackbar to >125ftlbs. I tightened my lower control arms too. I centered my steering wheel and adjusted the toe from 1/4" out to 1/4" in.
My question is could the slime I put in my tires (pretty good amount) be the cause of the DW. I always thought the rule of thumb was "if you have the DW, check your trackbar".
I read about the ball joints being a possible failure mechanism too. I lifted the Jeep and tried to wiggle the tires side to side and up and down. Nothing really.
I replaced my OEM steering stabilizer with a TennCo from NAPA, but when I put on the trackbar bracket brace, the angle is pretty great. It doesnt seem to be leaking.
any advise is welcome and I appreciate any feedback I get.

yeah, I read that too.
I dont care too much about the TPMS, I can check them periodically.
The TPMS is like watching the weather channel instead of looking out the window.
Of course my TPMS is working great, its just the suspension thats driving me batty.
Thanks for the input...

Boy am I glad you chimed in RNJ.
You've fixed my rig atleast twice before. (or atleast gave me advice that led to the solution) I think I'll get a bead breaker from northern tool and go in and get the slime out of the front tires.

I just had the inspection done, they're pretty liberal with the inspections over here. window tint is their big hit around here. I'm not really into the limo-Jeep thing...
When I upgrade to bigger meats and wheels i think the TPMS is pretty much useless anyway.

dad-gumm-it... MF'n JAMB NUT.
I left work for lunch and i got the DW twice. I went home and started going over everything again.
The TB ends were TIGHT and the drag link and tie rod were tight.
The jamb nut was tight too, but i had the steering wheel turned to get at it.
I thought to myself, when the wheel is turned, the TB is loaded.
I straightened the wheel and jerked on the TB and I felt a MY-NOOOOOT amount of wiggle.
I broke out the pipe wrench and found that since I put on the TB bracket brace, I only had about 5 degrees to ratchet the jamb nut between the draglink and the tierod.
Long story short, I got about a half turn (combined effort) on it.
I took it out for a test run and NO DW at all. I tried every pot hole around and I think she's cured now.
Lesson learned: DW is almost ALWAYS due to the TB.
Question: what color loc-tite is the stongest?
