Front driver's side creaking and clunk
2013 GL550 with 68k miles.
We are new owners and recently started hearing a faint one time clunk when accelerating at slow speeds (heard front drivers side). The one time clunk returns when I slow down to a stop. This also happens if I put it in neutral and slow to a stop.
Another issue, possibly related, is a terrible creaking sound (like a bed spring) in the drivers side front wheel area. The creaking is heard when driving or stopped. I can recreate the issue when standing on the running board and bouncing a little.
To troubleshoot these issues on the drivers side front, I had a new sway bar, sway end link, lower ball joint, and new Arnott strut replaced. The creaking and one time clunk are still there.
I've been reading every forum and can't decided what to do next. When doing repairs, everything looked good within the suspension. Any ideas? I'll post a video of the sound tomorrow. Thanks!




These issue are still there after new lower ball joint, new Arnott strut, new sway bar, and end link..... Please keep in mind all the sounds were there before and after the replaced parts. When holding the bottom of the lower control arm, I can feel the vibration from the creaking.

I ordered a new lower control arm and hope that fixes my issues.

Thanks!
My engine mounts are old but don't think they could make this thing sound like a '88 Ford Tempo.....
Same part # both sides?
Any other part #’s replaced at the same time such as the polyurethane bushings on the sway bar bracket?
I like to reuse OEM hw, usually better quality.
My suspicion is that its the Arnott struts that are a little over a year old, and clunking coming from internals near the strut mount.
Ordered:
a. from Mercedes star parts for the front:
1. 166-320-11-00 Stabilizer Link $70, Left
2. 166-320-12-00 Stabilizer Link $70, Right
b. from FCP Euro for the rear:
- Lemforder 164-320-1232 same for L and R, $30 each
Will be rebuilding front & rear upper/lower with new struts, bushings, etc. will take photos and post results. 2015 GL w/ 205k miles. Looking forward to many more as we really enjoy this vehicle. Cheers
The clunk/groan is audible when car goes over the long depression and the frame pushes downward. I may start spraying various areas of the suspension one by one with silicone lubricant to see if I can pinpoint noise further...
