Experiencing noises from your automobile regularly is never reassuring, so hearing noises on your Mercedes Classe V suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to resolve the problem, it is with this objective in mind that we wanted to write this document to support you see more clearly. We will first see the possible causes 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 Classe V
Check Mercedes Classe V suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Classe V, and it is characterized by a “clack” or cracking, it is highly plausible 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the problem that concerns you, take a dented road and focus on 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 affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Mercedes Classe V 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 old and the dirt/dust builds up inside them their action is degraded and it is possible to experience a noise 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 turn at low speed. If it cracks in these two conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Mercedes Classe V, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Mercedes Classe V passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components that may have been destroyed 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 special play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your Mercedes Classe V to your auto mechanic or change them if they are involved.
squeaky noise speed bump Mercedes Classe V
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Mercedes Classe V, 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 cause this squeaking noise. Please remember to check 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 dry and provoke 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, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Mercedes Classe V. To change them go to your auto technician.
Other speed bump noise Mercedes Classe V
If, even though all its assumptions, you still can’t locate the source of the noise your Mercedes Classe V makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Mercedes Classe V or to visit your auto mechanic in order to carry an in-depth check on your Mercedes Classe V and determine this problem.
