Hi Folks, I recently bought a 2000 model C240 [ build date December 2000 ]. It has done 143000 km. I notice that after driving it for about 20 mins, a noise develops in the front suspension. Hard to describe the noise, a 'graunching' sound like rubber against rubber. I can jounce both the left front or the right front & it makes the noise. I am not sure if the noise is on one side & this is 'referred' noise or if in fact there is a problem with the both sides. It takes very little car movement to get the noise, does not have to be a large bump to get the noise. Any common problems with these? Any ideas?
Thanks.

 

Record it and upload the video to youtube

 

Common sources are the Caster arm bushes or sway bar links & bushes.

Check for cracks & silicone fluid leakage from the Caster arm bushes.

 

Update. I replaced the front stabiliser bar pivot bushes with polyurethane bushes & so far no more front end noise. Will be doing the same with rear bushes.
