It was actually about a year or so ago. I felt pretty dumb when I figured out what it was.

Rancho kept telling me I didn't have my pitman arm tight enough. Gave me some unreal torque spec like 900 ft lbs or something. Had to pull some strings to come up with that torque wrench. Had to put a 6' cheater bar on it just to get it to click at the recommended torque. Still didn't fix it. Rancho tech kept telling me that's what the problem was and it was my fault.

I know I was ready to kill someone before I got done. I had heard of it but never experienced it until then. I like to joke around more than the average person. I found NO humor in that ordeal. :mad:

Good luck, you'll need it.

I have dealt with this exact problem also. We made small spacers to make sure that the rims centered properly. There is NO WAY that you can get them to center properly with out them ie. just using the lug nuts.

Like wardey said it is inherent in the design of the jeep suspension when you start lifting it.
If it does go away with weight in the back try putting in another 1/8" toe in. With the inverted y steering on jeeps lifting the front causes more toe in. That is a free fix if it works, just use a tape measure.
Second check to make sure the track bar bolts are TIGHT and the bushings/joints are in good condition. A good stiff trackbar makes a big difference too. JKS is probably the best out there.
Third try changing to a Old man Emu steering stabilizer. You wouldn't think they would be that much better than the big name junk but they are. Any changes you make can fix it even different shocks. You have to stop the harmonics in the susension that build into death wobble.
If none of that works I'll build you a kick ass Long arm setup and you will never look back ;)

Worst scare I had was pulling my 32' boat trailer home from LOTO and geting a bad case of the wobble on I 70 during rush hour. You should have seen my passengers face!

Thanks 320, Buck , and all. I have had enough !!!! Everything checks out ok, it goes away, we think it's correct, then it comes back !!! I'm ordering the Currie Heavy Duty Tie Rod system along with the Clayton Hard Arm suspension. I can't have him riding around in this shaker box !!!! Dave

Clayton makes a nice system. You won't regret it.

I had an 87 wrangler with Currie built Dana 44's on 38" Swapers with 4" leafs and an axle-over conversion and 3" body lift (with small block chevy drivetrain). It did pretty well at first, but as the tires wore, the "death wobble" got worse and worse (no steering stabilizer). The easy solution for me, was to put on an AGR "Rock Ram" system. This system consists of a modified steering box that gives you outputs for a hydraulic assist ram. The ram welds onto the front axle and takes care of any play in the steering system. It took care of the "death wobble" and later I moved up to 39.5" Iroks and still had no problems. You could turn lock-to-lock with just your finger tips at idle on pavement. Very good system and made street driving safe again. Worth every penny.

I had a 2000 Ford diesel van with the Quigley 4x4 kit on it. It had the same thing. It was fine to about 55 or 60. If I hit a bump in the road the "death wobble" would start. Very violent and scared the chit out of me. The only way to stop it was to pull over and start from a stop again. A friend was driving me home (too many drinks) and he tried to drive through it but it just got much worse. After replacing pretty much the whole front end, including tires. A guy at Quigley e-mailed me and told me to replace the Track bar bushings. I did with poly energy bushings and never had the problem again. A $15 fix.

I've done some Clayton long arm installs. Top quality stuff.

Go back to the basics, is your drive shaft out of balanc? Did you check pinion angles? Bushings? I had the same thing with my excursion. They checked everything and said it was all good. Well the carden joint binded and broke the transfer case adapter plate. Replaced adapter plate and both driveshafts and no more wobble. It appears that the carden joint or u-joint was bad. Good luck, kind of like chasing your own tail.

Nice Rig Baja !!!

Aqua, This thing feels like someone grabs the steering wheel and jerks it back and forth as fast as they can. I'm not kidding, IT'S VIOLENT !!! Feel's like the front end is going to come out from under you. Only at the 40-45 mph range. It's in the front end not the drive line, i'm almost positive.
