Re: 2014 GCs that have steering shimmy over 60MPH

Just a comment on the GY-bashing that was pretty heavy earlier in this thread.

I have no tire allegiance, unless it would be to Michelins. I just bought a new set of (17") GY Forteras because of the highway performance, not because they were a bit cheaper than the LTX. When calculating for the longer-lasting compound, the LTX are still a bit cheaper. But I couldn't risk that they wouldn't measure up to the Fortera's performance and MPG.

When a tire's even slightly out of round (balance), dont you hear it first? Slap-slap-slap-slap. You should hear it long before you will feel it. I'm not saying these 20" GY are not problematic, I just don't believe they're the only--or even primary--problem.

My 17" Forteras roll like billiard balls. I was stunned by the difference a new tire could make to cornering--even body roll. In the past when I renewed heavier-treaded tires I always took a performance hit in the early miles. With a moderate tread (but without a heavy sidewall) the new tires made this big rig feel like a go-kart.

I run 38-40 psi, the tire is rated for 44 cold. Manufacturers recommend lower psi to alleviate wear-and-tear on running gear. But in this case it seems to be wobbling something loose. Again, this steering wheel shaking is unimaginable to me. But I don't think it's the fault of the Forteras, no matter how good a value they are.

I completely disagree.... the biggest issues I have had having driven 4 different vehicles with the 20" Forteras is that they simply do not meet those mileage claims and over time have problems. The Durango I am driving is not my own but a dealer loaner and has Forteras and has less than 30k on it. The tires are probably 60 percent through their wear life and I have a steering shimmy just like so many of the people here describe.

I also get to see the number of times warranty claims go through for these stupid tires and it is way higher per capita than other tires.

Any new tire will be better but the Forteras simply do not have a good track record. I will tell you they are the primary problem.

You'll generally feel a tire that's out of round or out of balance (not necessarily the same thing) before you'll hear it. Especially in modern vehicles. Either a shake in the wheel, floor, or seat--in varying degrees. Generally in modern vehicles a tire needs to be REALLY out or have a visible bulge in the treadline before it will be heard.

Just noticed my tire pressure when i got the truck back. They r now set to 38. As opposed to 36 that is written on the door frame. I was able to (remembered to) check it once during the drive and noticed it was already up to 39 and it was a short drive. Will keep everyone posted. I have not been up to 60ish mph again.

Agree, especially in the Jeep with Double pane front side windows.

Re: 2014 GCs that have steering shimmy over 60MPH

Quick update, I have just about 5k Miles on my 2014 overland w/ 5.7L and 20" forteras and the shimmy has not returned since my Balancing at 2k. I hate to see some of you still fighting this issue. One other quick note I recently got a major questionnaire\survey type of email from Jeep regarding my experience with the jeep so far. It basically linked me to some customer service website for a survey. Have any of you gotten one of these? It was very inquisitive and not surprisingly knowing of most of these issues... in the sense that it asked if I had problem x or y... and low and behold this shimmy issue was one of them. I was honest about everything. They even asked, based on the content of my answer, if I would like a customer service rep contact me and take my issues to the next step. Sounds like something some of you might like to get. The only thing i've done thus far to register for said survey was purchase the vehicle and setup the uconnect stuff online...

Thanks 3Percenter3, I had the same survey and rated honestly. I had a call within 2 business days from Chrysler Care. Following the process through and responding in business tone will get you results. I just spoke calmly, stated the issues (no bad mouthing, no swearing) and ended up after a few more trips to the dealer in a replacement situation. I simply can't complain about the whole process dealing with Chrysler, they were always courteous and seemed to genuinely care about my satisfaction. I wouldn't say it was great having to have an issued filled unit, but at least action is occurring.

Took a trip up to the blue ridge this past weekend. I can truthfully say I didn't have much of a shimmy at all. Just to bring everyone up to speed, all the dealer did was adjust my tire pressure up to 38 and did a regular balance. Only 2 tires were out and 1 was very minimal. Temps in NC were unseasonably warm both back and forth and I kept an eye on my tire pressure...noticed yest on the way home a couple of tires ticked up to 41!! I'll continue to monitor it all and keep everyone posted.

It seems 38 lb reduced my shimmy as well.

Re: 2014 GCs that have steering shimmy over 60MPH

Forgive me for not reading all the posts in this thread (10 pages and growing), but I took my Jeep in for the BCM recall and radio service error over the weekend and the tech told me to come back later in the week for the radio and they had a fix for the steering vibration. That was the first I've heard of it and I've never noticed any vibration while owning the vehicle. Is this just a tire issue or is there really something mechanically wrong causing this issue? Again, maybe this has already been answered, but i thought it was strange for him to mention that and then I discover this thread.

500 miles driven since my last visit to the dealer to have the shimmy looked at again for the 3rd time. This time, it seems much better. I've been testing it on my way to work on smooth highway (recently paved) driving from 60 to 75mph and I do not see the steering wheel shake at all. PSI set to 36 cold. I'll give it another 500 miles until I put a stamp on it. So far so good.

So it's now been 750 miles and the shimmy has returned between 60 and 70 mph. I thought how can this possibly be all of a sudden from one day to the other. I thought perhaps a weight fell off. So I went around to each wheel and all seemed ok until I got to the front passenger wheel. It 'appears' that one of the weights fell off as it looks like there used to be one weight now missing from the clean area shape of a weight. Take a look and tell me what you think. If a tiny weight fell off would there be glue residue or would it come off clean as in this picture?
