Heard the same thing Invest.. and as I've stated in the past, three shops have said nothing's wrong after inspecting the steering system.
I think this is a growing issue because everyone's jeep reaching that point in it's lifetime where these things just happen.. at 64K we suffered our first shimmy, and at 70K we suffered our second shimmy/wobble.. but the best thing that's happen.. was removing the retaining clips.. termed "masking" any underlying causes. I'm disappointed in hearing about user saying that Duratrac has been known for these shimmies.. but this can't be verified.

 

I have read of many issues with the duratracs. My 2 sets have been great. My original BFG MTs wore unevenly to the point that is was literally undriveable. It started between 45-55 and eventually progressed to anything over 30. Rotation initially helped.

I do believe that the older my JK is that things will wear out and reveal themselves in wobbles and shakes. So far maintenance and updating has kept me ahead of the power curve. Good luck to the OP on this. Rotate and look for any subtle change. Loosen everything and retorque to specs. Look for any worn parts. I know it's frustrating but hang in there. You'll find it and resolve it....I'm sure of it.

 

It's a 2014 JKU with 2000 miles. 2.5 inch SPACER lift so it didn't require much loosening of alot of front end parts. I'm running 35 inch Duratracs. And I have installed a dual stabilizer kit with no difference.

 

Hmm, well then that may be the issue. Spacer lift, coil lift, big 6" lift.... They all require that you loosen all of the control arm and track bar bolts. If you don't, you'll likely bind the bushings.

Your call though. It's free to loosen all the bolts and retorque. Or you can toss money at it.

 

Did you buy from goodyear or have free lifetime balance on them? If so I highly suggest taking them back and asking for them to be match mounted. Just Google search for a detailed description. I only had about 10000 on mine when the lift went on. It drove perfect from the shop where I installed the lift to the tire shop with the original tires on it. I talked with the guys at goodyear and was told they have to match mount most of the duratracs to get the steering wheel Shimmy to go away. Don't know why they didn't do that in the first place but all is well now.

 

I had a local custom shop do all the install and order the tires and wheels. I guess it's time to take it back and have them go over it again.
