Finding out noises from your automobile frequently is never reassuring, so discovering noises on your Mercedes Benz GLC Class suspensions when you pass a speed bump can be worrying. This sign may be a sign of a small problem as well as a warning of a much larger repair to come. In any case, it is essential to check the cause and take the necessary actions to resolve the problem, it is with this aim in mind that we wanted to write this document to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, what can be the reason of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Mercedes Benz GLC Class
Check Mercedes Benz GLC Class suspension
If you encounter a suspension noise when you pass a speed bump on your Mercedes Benz GLC Class, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 examine if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them fairly quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have searched for “Mercedes Benz GLC Class 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a sound when they are in torsion. To examine 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. If you have the feeling that this noise is more like a a loud noise on Mercedes Benz GLC Class, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Mercedes Benz GLC Class passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply 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 normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, put it under the automobile and apply twists on each of its elements to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your Mercedes Benz GLC Class to your auto mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Mercedes Benz GLC Class, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Please remember to examine by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, 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 happens when you pass a speed bumps or any holes with your Mercedes Benz GLC Class. To swap them go to your auto mechanic.
Other speed bump noise Mercedes Benz GLC Class
If, despite all its assumptions, you still can’t uncover the origin of the noise your Mercedes Benz GLC Class makes when you pass a speed bump, we suggest you to refer to this article on a loud noise on Mercedes Benz GLC Class or to visit your auto mechanic in order to carry an in-depth check on your Mercedes Benz GLC Class and identify this problem.
