Hello. My 2001 C240 Sport has some front end noise when I go over bumps or dips. It sounds like the springs or bushings need a good spray of WD40. Noise is similar to a creak. Is this normal? Am I looking at a repair job here?

 

Most likely your lower and upper control arms bushings are shot. This is a problem area in model year 2001

 

It could also be the inner stabiliser bar bushes. A bit of graphite powder wil make these quieter if it is your problem.

 

Anti-roll bar bushings. Very common & easy to replace with the proper tools.
