If you stay within the speed range of the wobble does it just wobble a little or does it get progressively worse to the point you feel like you're going to crap your pants?

I had a similar issue with my TJ and it ended up being the tires. It wasn't death wobble (the front wheels oscillating violently back and forth) in my case, it was more of an up/down side to side bouncing that would feed back through the steering wheel. If I stayed within the resonant speed range for long it would start to get scary.

Were the wheels and tires mounted locally? If so, I would take them back and ask them to spin each one up on the balancer. YOU need to be there and watch them spin. I'll tell you what to look for. Look at the very edge of the rim and the side of the tire as it spins. The tire and rim should spin "together". If it looks like the wheel is straight and the tire is "wobbling", then that tire needs to be aired down and broken down on the wheel. They need to lube the beads up VERY well, and then "turn" the tire 180 degrees on the rim, and air it back up to around 60 PSI and then back down to the proper level. This will ensure that the tire is on the rim straight and it has "popped out" all the way. Lots of times tires will be stubborn to seat all the way. Sometimes they need a little persuadin. Also of course, look for a bent rim while on the balancer. If you got them online, I notice you're in Marietta. It would be a bit of a drive, but I know a very reputable tire store in Macon.

before you jack the jeep up or even after, start the jeep and have someone slowely move the steering wheel left to right, while you lay on the ground and check for movement in parts, look at trackbar and bracket, and other parts, that should show if there is anything loose or broken,

I do this on a reg basis, to check components,

It never gets progressively and I'm yet to feel as if I'm going to crap my pants (thank god) and I don't get a feeling of bouncing it's more of a vibration (i think)

N2rock, you pretty much hit the nail on the head, thats the exact problem. So you had the problem with stock wheel/tires; I guess this means it's possibly not a wheel/tire problem and more of a suspension component problem? Have you done anything about it or are you still looking for a cure?

I did get the tires locally (Discount Tire in Kennesaw, GA) and I just had them balance the tires again but I could take them back and ask to watch and maybe teach them a few things about balancing tires, wow you know a lot about balancing tires, lol. Or do you think I should just take them to the local 4 Wheel Parts and explain my issue to them? I probably should have just bought from them in the first place...

I had the problem and then put my lift on and checked all the components, and I don't think anything is broken. I know my drag link and tie rod feel loose and have metal on metal contact when I turn them but I'm not sure what to do and the dealership says nothing is wrong. I'll go ahead and try that though and check my trackbar.


Thanks to everyone who has responded, I appreciate all the advice and help.

Well, I was a mechanic for almost thirty years before I was disabled, so I have balanced my share of tires. I wouldn't go in acting like you got advice from anyone. Just let them know what your problem is. They will in all likelihood fix it.

The size of the tires may be too much for the stock steering stabilizer to dampen. I got a couple of months out of mine, until the 35s were too much for it. I replaced it with a Rancho and shimmy went away...

I had these same wheels and had avibration problem with 2 of the 4 I got from Quadratec, it seems steel wheels just can not be trued as well as most cast wheels and once I rotated the two "problem" rims to the rear - the vibration went away. By the way my vibration was around 67MPH. Also Cragar is horrible at shipping these wheels, the first 3 were sent back because of obvious dents on the rim edge.

I actually just started having this problem. Seems to be 40-50mph, right around 43mph. I've been running 17" Cragar Soft 8's on 33" Pro-Comp Xterrains. I've had the wheels and tires on since January and never a problem. I had it in the shop for the transmission TO bearing TSB and had them rotate the tires while it was up. Now I've got the shake.

I re-torqued all the wheels to 90 ft. lbs. when I brought it home. My next step is to rotate the fronts to the back and see what happens. Also going to get the balance rechecked.

My wheels were shipped from Summit. The first set was totally destroyed. The second set was much better but far from perfect.

Take it back to the tire shop you have a balance issue. Balance issues are most common at or around 30-35 mph but 45-50mph is not un herd of. Then again on some of the really big CHEAP tires you will never get a perfect balance job. Back in the early 80's the bias ply gumbo mudders where almost impossible to balance. Thank God for radials.

I had this exact same problem when I bought a new set of steel rims. They were called (gunners) I don't remember the company. They were about a 100 bucks a piece. Anyway, I took them back and got another set and the vibration moved to the other side. They sent them back a second time and got me a completely new set and the vibration moved again. It was always within a 3 to 5 mph range. If I went slower is disappeared and if I sped up it disappeard.

It was then that I decided that you couldn't get a decent set of balanced steel wheels and I put the stock ones back on and everything worked great.
