ML 320 Squeeking Noise from underneath
 

Recently I am experiencing a squeeking noise coming from front underneath when going over the bump. Initialy it was negligible, but as times go on it is increasing more and more. Can any one tell me what is causing this, and how expensive is the fix ? I just joined the forum and new to it. Information here are very usefull. Thanks.

could be ball joints the fronts or the backs. and also could be the torsion bar support needs to be replaced.
