I am losing my mind over this. I bought a 2013 c63 in May and the last few months it has been making this clunking noise. I have taken it to the dealership 3 times so far and each time the noise goes away for about a week only to return worse than it was. It used to only make noises when I turned right on incline changes at low speeds. Now it makes the noise going over any bump at any speed.

The first time I took it in they replaced the front left strut. The second time they replaced the front right strut. The third time they replaced the lower control arm.

I am posting 2 videos of the noise. This video is between the first and second visits and the noise can be heard around the 24 second mark.


This second video was taken today, 2 weeks after my third visit. You can hear the noise continuously throughout the video on any slight bump.


Any and all advice as to what this is would be greatly appreciated.

Maybe your front strut bearing. https://mbworld.org/forums/c63-amg-w...t-bearing.html

Would that not get replaced when they replaced both front struts?

Check your repair receipt for 2049810025 and see if the part was replaced w/ the struts. If not there, ask your dealer. Most dealers will replace only worn items and will reuse related items if not worn, especially if under warranty.

8o8is is correct, that sounds like an upper strut mount bearing.

sway links?

I personally think this is WAY louder than bad end links. I'd give the upper strut bearings a shot, but am not too confident that's it either.

I know this sounds dumb, but are you sure it's not from inside the car? I had an annoying knocking over bumps too, and I realized it was the passenger front seat belt buckle hitting the seat plastic trim on the door side.

that definitely sounds like your struts. Do you have suspension on the car? I have H&R on the car and my struts had to be replaced because of that exact sound. The sound was especially stronger when going over decline bumps or over speed bumps below 5-7 mph. Keep in mind, if you do have suspension and are still within the 2 year warranty, the company should replace them for free

Front strut bearings. Easy to swap out and 99% that's ur issue. One or both. They are also not expensive.

Since ur under warrantee dealer should do that.

A lot blame aftermarket springs or struts but they can just go bad. Probably not the best design.

Kriston

I have H&R Coil overs and they destroy strut mount bearings. The top mounting assembly on the W204 are not aftermarket strut friendly. I believe those with KW suspension don't have this issue as they have revised strut mount assemblies with the kit.

Eric ATP

I also have h&r coils but my car has had no issues. 2 friends with other setups have had issues. I think it's really more complicated and I for one have no idea the cause of the issue.

I know the amg GT guys where having strut issues but there has been some changes to address that.

Itsbrad

Thanks everyone for the input. It seems like the general consensus is the strut bearings. I have an appointment with the dealership tomorrow so I will bring this up to the advisor. I really hope this gets resolved.

Eric ATP

You can always try smashing it into a tree at moderate speed. I had a rear deck lid rattle that drove me crazy that I finally fixed. The thought crossed my mind many times. ��

Itsbrad

Haha, that is on the list but there are probably 100 other options ahead of it.

You find out that it was the strut bearing?

mikekuriger

mine makes a clunk sound also, but not like yours. mine turned out to be the spare tire bouncing in the trunk.

Itsbrad

Got it back from the dealership and they said they put some copper lubricant on the sway bar. So far the noise has stopped but we shall see.

AMG3.2

That's great news. At least you know where it's coming from.

itzjonjon69

I just noticed that i'm getting clunking noises when driving on rough surfaces/streets and also when i go over bumps etc. Sounds like it's coming from the front passenger side. Currently lowered on H&R springs wonder if this could be causing my problem.
