Suspension cracking noise Mercedes Classe C 2
Check Mercedes Classe C 2 suspension
If you notice a suspension noise when you pass a speed bump on your Mercedes Classe C 2, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 check if this is the problem that concerns you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them fairly quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Mercedes Classe C 2 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is degraded and it is possible to experience a sound when they are in torsion. To check 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 situations you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Mercedes Classe C 2 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been broken by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, put it under the car and apply twists on each of its elements to check that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Mercedes Classe C 2 to your auto technician or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Mercedes Classe C 2, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Bear in mind to check by going under your car the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case remove them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the auto, a noticable weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Mercedes Classe C 2. To change them go to your auto mechanic.
