Suspension cracking noise Mercedes Benz C Class
Check Mercedes Benz C Class suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Benz C Class, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them fairly quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Mercedes Benz C Class suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a sound when they are in torsion. To verify this, you can try both types of torsion, first vertical with suspension compressions on the speed bump passages, and horizontal when you are going to make a turn at low speed. If it cracks in these two conditions you should consider replacing it or them.

Check the stabilizer bar

Check engine silentblocks
