I've about had it!!! Needs fix or am selling

So I have a 2007 2 door rubicon that I have highly modified.

It has

Yukon 5.13 gears

Off road evolution sleeves and c gussets

Rock krawler 3.5" mid arm flex lift

bilstien shocks and steering stabilizer

Rock krawler hd drag link and tie rod

Moog tie rod and drag link ends

Poison spyder front and rear bfh bumpers, diff covers, crusher corners, rocker armor, an rocker knockers, tramp stamp, hood louvre

Warn m8000 winch with synthetic rope
Synergy hd ball joints

Trek armor seat covers

Daystar dash components

Best top trek top nx

Tom woods 1310 drive shafts

37" Goodyear mtr w/ Kevlar

4 ATX slabs beadlocks

MBRP off road exhaust

K&N air

Diablo predator programmer

Smittybilt flat fenders

Viair on board air

Hi-lift jack and accessories

Rugged ridge hi-lift mount

Dupli-color beadliner with Kevlar interior

Lube locker diff gaskets

Tuff Knucks gloves for off road use

Or-fab heavy duty crossmember

Truck litez LED headlights

Rigid industries duallies

However I still have this death wobble that comes and goes. All tierod ends an ball joints are new. The lift has 20,000 miles on it but everything else listed is new. I'm at my wits end.

To top it off it's started making a strange sound that almost sounds like it's coming from the t-case.

Anyone want to help?

Loose track bar? Have you followed Planmans "how to" for diagnosis?

First thing, put a little bit of Toe-out in the front of that thing, The caster is probably a little jacked up. Now if you adjusted the lower control arms (or upper) to get your caster fair then the angle on your front drive shaft might be a little jacked up and causing the drive-line vibration. So I would take out the front drive shaft or just take it from the axle end and tie it up and see if the vib sound goes away. Swap tires from front to back. These are things I would try. Also are the unit bearings good to go?

It's only got the adjustable lower control arms. It drove great after I did the lift 20k miles ago and never had an issue until recntly. All bearings are new in both axels

Ok, then what could have changed? Tire wear, wheel balance, wheel bent, track bar hole or mount hole wallowed out or bolt came loose. Or, control arm bolts came loose, or bushings worn?????? Many things up front. I usually take a day out and check and re-torque everything, and when I say everything, I mean everything up front.

Correct.

People toe out when they have worn ball joints to band aid it until they replace them.

^this will fix it !

reading this thread prior to ever experiencing death wobble I knew what the usual culprit was. After getting it after a wheeling trip I was able to climb under it and diagnose it in a parking lot in about five minutes. - track bar holes ovaled out - ordered an artec bracket for the axle and a poly frame side bracket, in the time it took me to get to them it happened a handful of times, resulting in new joints for the track bar being needed.

sometimes its as simple as retourqing the track bar, but willing to bet your bolt holes are ovaled out at the track bar, and there is play -

cliffs - get someone to move the steering wheel back and forth while looking at your trackbar, and you will most likely see the movement in the joint area prior to the wheels turning.

10jk is right about the drive shaft. My 2011 just started making a squeaking sound. The girlfriend was driving it and told me about it - and from here description I couldn't understand what it was. Finally when I got back on the east coast and drove it, heard it, had her drive slow and I followed listening for the sound and I was 90% sure it was my front drive shaft (ds). Posting in a few groups they all concurred with my thesis so once I get it back from the dealership today (they couldn't tell where it came from - never going back to this dealership) i'm taking it to a shop and have them look at my ujoints on the front ds. Good way to tell is to remove your front ds and drive - if the sound goes away there's the issue. hope this helps.
