Listening noises from your car frequently is never comforting, so listening noises on your Mercedes Classe Glc suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the cause and take the necessary actions to eliminate the trouble, it is with this aim in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, what can be the cause 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 Classe Glc
Check Mercedes Classe Glc suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Classe Glc, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are old, 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 trouble that concerns 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 swapping them as soon as possible 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 searched for “Mercedes Classe Glc 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two circumstances you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Mercedes Classe Glc passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the case, the components that may have been damaged by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, position it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your Mercedes Classe Glc to your auto mechanic or swap them if they are involved.
squeaky noise speed bump Mercedes Classe Glc
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Mercedes Classe Glc, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Remember to verify by going under your car the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them off from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a evident 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 Classe Glc. To change them go to your technician.
