Discovering noises from your car regularly is never reassuring, so listening noises on your Mercedes Benz Sprinter suspensions when you pass a speed bump can be stressful. This symptom 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 origin and take the necessary actions to solve the problem, it is with this objective in mind that we wanted to write this document 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 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 Benz Sprinter
Check Mercedes Benz Sprinter suspension
If you notice a suspension noise when you pass a speed bump on your Mercedes Benz Sprinter, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Mercedes Benz Sprinter 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 amasses inside them their action is degraded 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 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 Sprinter, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Mercedes Benz Sprinter 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 situation, the parts that may have been destroyed by usual 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, place it under the automobile and apply twists on each of its components to verify that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic or replace 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 pass a speed bump with your Mercedes Benz Sprinter, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Bear in mind to verify by going under your automobile 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 remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case 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 fatigue of these will make 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 Benz Sprinter. To replace them go to your technician.
Other speed bump noise Mercedes Benz Sprinter
If, even though all its assumptions, you still can’t locate the source of the noise your Mercedes Benz Sprinter makes when you pass a speed bump, we suggest you to read this content on a loud noise on Mercedes Benz Sprinter or to visit your auto mechanic in order to carry an in-depth check on your Mercedes Benz Sprinter and discover this problem.
