Hearing noises from your car often is never comforting, so listening noises on your Mercedes Vito suspensions when you go over a speed bump can be disturbing. This sign may be a sign of a insignificant problem 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 resolve the problem, it is with this intention in mind that we wanted to write this document to help you see more clearly. We will first see the possible causes 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 Vito
Check Mercedes Vito suspension
If you experience a suspension noise when you pass a speed bump on your Mercedes Vito, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 examine if this is the problem that worries 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 replacing them fairly quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Mercedes Vito 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 conditions you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Mercedes Vito passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been broken 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 examine it, place it under the car and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or change 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 go over a speed bump with your Mercedes Vito, 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. Keep in mind to examine 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 bring on noise, in which case disassemble them 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 operate as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Mercedes Vito. To swap them go to your technician.

If, despite all its assumptions, you still can’t find the origin of the noise your Mercedes Vito makes when you pass a speed bump, we suggest you to read this content on a loud noise on Mercedes Vito or to visit your auto technician in order to carry an in-depth check on your Mercedes Vito and identify this problem.
