I have the same issue with a 2017 Limited which does not have the air suspension. It squeaks when I go into my driveway. It squeaks when I come to a stop going forward or backing up. Dealer can't find a thing wrong. Just started doing this about three months ago. Very frustrating. One thing I have noticed my 2010 Limited was a much better car than the 2017. Fit and finish was much better as well as the quality of interior.

i said it before, its your upper control arm. I am convinced the torque spec on the upper control arm to body mounts is too low for the WK2 model. The WK was specd at 80ftlbs and the wk2 is specd at 40 ftlbs. There is no reason for the reduction of torque. When it is at 40 vs 80 it is allowing the rubber bushing to move and squeak. In some cases it can even clank. Tighteing it to even 60 ftlbs stopped this issue for me and my buddy who has a 2018 with air suspension (and for me I don't have it)

Finally fixed the problem by replacing the subframe bushings. The issue is gone.

I hope you get it resolved.

I've got a clunking noise on my '17 trailhawk with the QuadraLift. Dealer and I tested three or four and they're all the same so I hope it's not "normal"

I know this is an old post, but my 2020 Grand Cherokee Trailhawk also makes a clunking noise in the front end going over speed bumps. Dealer also said it is normal. Was there ever any resolution to yours?

As an update, today I drove a 2021 Grand Cherokee Trailhawk and it makes the same noise - so apparently normal??

Was you driving at normal ride height?

 

[MarkB1]

Yes, normal drive height.

My 2015 Jeep Grand Cherokee Overland has been at the dealer since 1/14 for the same clunking noise mainly on the left side. They didn't hear any noise at first, one tech suggested raising it to a higher level and that's when they heard it. They couldn't find anything wrong after going over everything but said there is a bulletin about this issue and it happens when driving at higher suspension and apparently it's normal and to just drive at lower levels. I don't drive on raised suspension, it's on auto. And you can't drive normal on raised suspension, going off road isn't something I do either. Frustrating as nobody wants to hear that and I just really have a hard time believing it's "normal".

Since the beginning I have had a suspension noise on the front left on my 2015 Grand Cherokee Overland 4x4. When I got the car brand new I would only notice it on very high speed bumps at low speed. It has been getting progressively worse over the past year that I owned the car. I have had it at the dealership twice, however, they "cannot find anything wrong" - which I find ridiculous. Even took the technician on a test ride, he acknowledges the noise but said it is normal for the air suspension. I tried to explain that if it was normal, then why does the right front not make the noise and he had no counter argument... What I noticed recently is that the noise gets worse the colder the temperature. I uploaded a video demonstrating the noise:

Does anyone have any idea what this could be / where it is coming from? Is this really "normal"? Ben

My 2016 Jeep Grand Cherokee Lorado makes that exact same sound you have in your video crunch/squeek/ creek. It's been driving me crazy. And just like you mentioned it mostly goes away after driving around for the day or in warmer temps. Did you ever find a fix?

I took it back to the dealer in December, at first they thought it was the control arms / control arm bushings which were of course not in stock. After a week the parts came in and they replaced them but the problem was not resolved. They then suspected the sway bar, which also was not in stock, after another week waiting they replaced the sway bar and bushings which finally fixed the issue.

Hi Ben! I see now that you got it resolved. That's awesome! I have the exact same problem/ sound you explained perfectly and also posted video of.. Thank you for that. My question is did they need to replace the sway bar bushings AND the sway bar? or just the sway bar bushings.
Many thanks Ben sincerely!

The bushings are molded to the sway bar, so the bar and bushing are an assembly, they don't come separately. There are tips in the maintenance thread of how to remove the bushing and replace with aftermarket bushings, some with better durability than others.
