I think Jeep addressed a lot of issues that went into production in the "Mid Year" model.
Not only did they fix a lot but they also added features mid year(funny calling it mid year and its still over 2 months until we hit 2014) so a note to self let line run six months before buying a new model next time lol.

I agree the new features are great. I'm simply amazed at how well the acc works. Still having anxious moments waiting for it to shimmy, but...it stays steady as a well trained soldier. I know many on this forum bash Chrysler, but if you remain business like in your response to them, they do respond. Maybe, their approach is changing vs. how earlier owners were treated. But I'm very pleased with them.

I'd be interested to know what Chrysler did to the later builds to remedy the shimmy issue?

It's tires guys. I have an beginning-of-October build that I took delivery of last week. I noticed the shimmy the next day. It wasn't severe...but it was there. Took it to a good tire shop, had it road-force balanced and no more shimmy.

The variation you're seeing is likely due to tire batches--some worse than others in terms of road force.

I have the same shimmy/shake in the wheel. Feels like the left front. I'm taking the 20's off for the winter and putting on a winter rim/ tire setup @ 18". I'll get my guy to check the balance on that tire as well. Are you guys only experiencing this with the 20's? I've heard from diff tire guys that the bigger the rim/tire combo the harder it is to balance. Road force seems to have the best results.

Filled my coopers up to 36 cold (31 degrees yesterday am) still had a shimmy so I'm not thinking tires are the real problem next oil change I'll have my guy check the balance

Mine had it with the 18s and Michelins in the ORAII package. Road force balancing and indexing took care of it.

I believe there is still some inherent design issue in the suspension that makes them extremely sensitive to any slight nuance in the tires. My first 2014 GC had all 4 tires/wheels road force balanced to within 5lbs, with 3 of the 4 coming in at zero. It still vibrated. Now, my new one, is smooth as a baby's butt, but it still has the GY Forteras. I wish they would take one of the vibrating ones back to the proving grounds to diagnose once and for all.

Then, honestly, I would question the equipment used to road force balance those tires, or the people telling you they came out that way. ZERO road force variation on a standard production tire is EXTREMELY rare, and to get three out of 4 saying ZERO would be such a statistical oddball. They all have some variation--the really really good ones will be in the 2-4lbs range. One lb is an extremely good tire/wheel combo. Zero is VERY VERY rare...except...on equipment that is used improperly or is badly calibrated.

Which brings me to this: did you have those tires done at the same place repeatedly? The place, and how they were using the equipment can have a huge impact on the success of fixing
the issue. I've tended to find that specialty tire shops tend to have better trained people and keep their balancer calibrations up better than dealerships or discount chains.

I have followed Shoestring's problems since very early on. I do agree that the Forteras are terrible tires and why when my new truck arrives I am taking them off. Back to your earlier post yes there are some better batches but there was definitely some driveline problem that Shoestring's dealer could not fix.

Also yes in it extremely unlikely to get the rotational force on a tire rim assembly below a pound or two. I have seen it but pretty frigging rare.

Ah...I haven't looked at shoestring's posts. You mentioned driveline...that's a whole other issue. Typically that won't show shimmy in the steering wheel but rather a body vibration or, if it gets into the steering wheel, it'll be a "nibble" or "shake" that isn't side-to-side but more random.

Actual driveline vibrations are simply a nightmare. I've seen perfect setups that vibrated no matter what you did to them. Then again, I've seen simple shaft runout issues that dealers didn't fix because they didn't understand some basic driveline concepts and made the issue worse. So I understand the pain there...

PETER_K, yes, the wheels were first balanced by the dealership. They determined their equipment was not calibrated correctly and sent it down to the performance tire shop down he road. When Chrysler sent their field engineer he put the vibration analyzer on the car and determined it wasn't driveline related. They wanted to put a heavier steering wheel on mine from a Ram. I said no, and went the replacement route. I think the earlier post about damping forces could be dead on. However, at this point, I'm highly pleased with my new GC. I will continue to follow this thread in hopes a fix does come for the numerous folks in this boat.
