Hello all,

I have an 09' W204 and have had a knocking noise coming from my front passenger side wheel well for some time now. Initially I only heard the noise while driving over bumps and over the course of 3-4 months has progressed to a more constant knocking noise while driving at slower speeds. Does anyone have any idea what could be causing this issue? I've looked around that area a few times with my car raised up and didn't see any obvious signs of damage or wear and tear. but I'm not a mechanic and may be missing something. Any insight would be appreciated.

Thanks

I too had a knocking noise in front right wheel well. I thought it was the sway bar links, I replaced them and still had the noise. Then I got it up on a lift and found there was a rock wedged between the frame and a shield. Once I removed the rock the noise went away. This might help.

Possibly, thanks for the reply. I'll look into it, but it does have a more mechanical sound.

Could it be ore like a clicking sound? Maybe a bad CV joint?

i just recently got one. It sounds like a low pitched hollow noise. Ill see if there are any rocks, which actually would be a culprit in my case...hopefully its that easy.

There is a sticky in the W203 forum that would be worth a read.
The W203 and W204 have very similar suspensions.

I could describe it as a clicking noise I suppose. I'll look into the CV joint. Could you tell me what I should be looking for?

Thanks. Could you post the link?

Its at the top of the W203 forum, where all the other stickies are.........
Now open wide and here's another spoonful.....:-))

A clicking or popping kind of sound when turning. Check the rubber boots to see if there are any tears on them. That could allow the grease in there to escape and could help cause and exacerbate the issue. Do a quick internet search on a bad CV joint and you'll get a bunch of good explanations and pictures that would help you.

Goof luck. Hope you get it sorted soon.
