Michael Storm Latest update, tightening the trackbar fixed the immediate and constant death wobble, and applying my transfer case lower kit eliminated the rest of the smaller vibrations. BUT, I still have the death wobble coming indefinitely from my front left tire at right about 40-45 Everytime. Usually when I hit a little bump is when it goes really crazy. Still trying to figure this last one out. My next bet is the wheel spacer possibly.

ChaddG This is a long shot, check the fuel system for the code. This could also cause a wobble in the engine or a shake of sorts. It did in my 2001 tj.
make sure your steering gear box it good too. This caused a huge wobble in mine.
Turn your wheels left, turn off the jeep. check for free play in the wheel
do the same for the right side.
with someone under the jeep,
check your tie rod end on the drag link
check your bushings in the track bar.
tie rods/ ball joints
all this while someone shakes the wheel back and forth, a good 4 inches on the wheel.
make sure you have no torn boots on any parts
as Jerry said, make sure your spacers and wheels are torqued correctly.
make sure your tires are inflated properly, lets not forget a proper balancing on them either.
sway bar links look new,
I found when my gear box went bad, I was constantly steering left to go straight, when I turned my wheels left to park, I had excessively abnormal play in the steering wheel but the rest of the suspension components were tight.
when I changed my fuel sending unit, the engine shake went away.

Michael Storm Tightened the trackbar. Fixed the constant DW. Still have a random DW thought that usually will happen right around 40-50 in 4th gear, normally Wi hint seconds after I shift into 4th. I haven't taken off my wheel spacers yet and I'm thinking that might be what's causing the remaining DW, will test that theory soon. Also CEL has cleared on its own after I tightened the gas cap and drove for awhile on it.

Several seconds will pass before it will start displaying any stored DTCs so give it a little time.

NoBoat0429 If you fill up w gas, tighten down and drive for a bit, the code will clear. Anybody else know how to clear codes?
06-20-2013 03:03 PM
Michael Storm As for the CEL code I tried tightening my gas cap (it was a bit loose) then turned my engine on but the light was still showing. I'll check more into that later.
06-20-2013 03:02 PM
Michael Storm Figured out what it was once I had time to look it over. It is indeed my trackbar. The hole I had made intentionally for the new trackbar mount was too close to the old one. Even though I had just put it back it in the old one it broke a little bit if the metal bracket bridge in between the two holes, allowing it a little but if play back and forth with something as simple as me turning the wheel. Will patch it up with a welder, re tighten in the original hole, and hope that fixes it; which it should very well.
06-20-2013 12:47 PM
cballou I know when you install a lift they suggest you tighten your track bar after the first 50 miles. Seeing as you had your disconnected during install you may want to re-tighten. I know that is what caused my DW. After I torqued down both sides of my TB (again) I haven't had any issues.
06-20-2013 11:55 AM
Wattapunk Any play in the front trackbar bolt will cause or promote DW. Make sure the front trackbar axle end bolt is torque to 55 ft/lbs. Double check swaybar end link bolts or any front end bolts that were removed for the lift. As for the code, like others stated, check your gas cap and also check the evac canister and associated rubber vacuum hoses for cracks. There are some rubber hoses located under driver's side undercarriage that sometimes get deteriorated or missed when checking.
06-20-2013 11:03 AM
Michael Storm Loose connections? Like the hardware being loose?

No, the location of the track bar won't cause the dw, it just centers the axle in relation to the body and gives lateral support to the suspension components, but loose or worn connections on the ends of the track bar will definitely cause dw.

sevenservices check your wheel hubs. If you jack up a tire and try to wiggle it around and feel any play in it, replace the hubs. I'm thinking maybe the wheel spacers are applifying a problem that may have already been there, just easier to notice now.

Just a thought... I know a little play in a wheel hub can really throw the front end out.
06-20-2013 08:01 AM
NoBoat0429 Make sure to turn off the jeep while getting gas too.
06-20-2013 04:57 AM
tkfx P0456 can be caused by a loose gas cap. Make sure your gas cap is tight. I wouldnt worry about this check engine light until you get your DW solved. The P0456 shouldnt have any major side affects, as it is related to the fuel vapors and preventing it from evaporating from your tank.
06-19-2013 09:00 PM
Michael Storm Also the code that pulled up was P 0456. I Googled it and it appears to be a small evaporation leak. So unrelated to the death wobble unless it busted one of my hoses?
06-19-2013 08:58 PM
Michael Storm I did this, but it didn't work. The hardware that the bolt has to thread with (a nut, but one that's tack welded to a piece of sheet metal, not sure what it's called) does not fit in the spot where the new hole is. I think the hole would have to be higher for it to work. So I guess I need to take it to a fabrications shop and have them patch the hole that I just put in it. See if a new one works. Is it that necessary to get that done ASAP? I'm thinking the death wobble was caused by something else seeing how I was driving with the track bar in its original spot for days before this happened.

The reason you couldn't get it in is because the track bar was unbolted from the original location and the nothing has moved. With the track bar unbolted at the axle and with the jeep sitting on the ground, have someone turn the steering wheel until the bolt hole lines up.

Then ng is it was fine driving for a couple days like I said, but something is suddenly going wrong. I feel like something has come loose.

jkp To get the codes: On Off On Off On quickly. Codes will display in the odo.

Wattapunk You can definitely adjust the toe-in yourself see link below. Have you tried disconnecting the battery to see if it will clear the code?

Yes, alignment would take care of toe-in.

The sway bar links wouldn't cause the wobble you're experiencing, but for a little more clearance, reverse the upper bolts on the links.
06-19-2013 03:30 PM
JFjeld Good luck with your diagnosis.

06-19-2013 03:06 PM
flash1034 Caster is an alignment perameter. Do a search for a technical explanation.

flash1034 I thought it was 5 times on the key trick. Try that.

Michael Storm What is caster?
06-19-2013 03:03 PM
Michael Storm Would an alignment fix the toe-in? I tried that trick to get the code like you suggested but nothing happened. Is it supposed to display where my miles are? Because that's the only digital part of my display. And All that happened was the CEL flickered a couple times then stayed on. Nothing else. Maybe I am doing ng it wrong? Anyways over lunch I was able to check components for play but did not have time to do some like the wheels and spacers because I have to wait to get a jack/torque wrench from my buddy after work. I didn't see play in the track bar, from what I can tell. But I did notice my front right sway link seems to be hitting my frame. Took a picture of it and the front left that's not hitting for comparison. Idk if that's a problem that's contributing to this or not but here it is.

flash1034 My guess is too little caster after the lift. You're getting the shopping cart wheel effect.
