Finding out noises from your automobile often is never comforting, so discovering noises on your Mercedes Classe B 2 suspensions when you pass a speed bump can be disturbing. This sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to correct the issue, it is with this objective in mind that we wanted to write this article to help you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 B 2
Check Mercedes Classe B 2 suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Classe B 2, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Mercedes Classe B 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Mercedes Classe B 2, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Mercedes Classe B 2 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the components that may have been affected 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 verify it, position it under the car and apply twists on each of its components to verify that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Mercedes Classe B 2 to your auto mechanic or replace them if they are involved.

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 B 2, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Keep in mind to verify by going under your car the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them out from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a evident weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Mercedes Classe B 2. To change them go to your auto mechanic.
Other speed bump noise Mercedes Classe B 2
If, despite all its assumptions, you still can’t find the source of the noise your Mercedes Classe B 2 makes when you pass a speed bump, we recommend you to read this article on a loud noise on Mercedes Classe B 2 or to visit your auto mechanic in order to carry an in-depth check on your Mercedes Classe B 2 and discover this issue.
