Experiencing noises from your car often is never reassuring, so hearing noises on your Volkswagen Multivan suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the cause and take the necessary actions to solve the problem, it is with this intention in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 Volkswagen Multivan
Check Volkswagen Multivan suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Multivan, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. Indeed, 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 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 drive over holes. If it is indeed the cups, think of replacing them 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 “Volkswagen Multivan 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 accumulates inside them their functions is deteriorated and it is possible to experience a sound 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. If you have the feeling that this noise is more like a a loud noise on Volkswagen Multivan, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Volkswagen Multivan passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary direction. If this is your situation, 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 origins of your noises, to verify it, put it under the automobile and apply twists on each of its elements 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 vehicle to your technician 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 Volkswagen Multivan, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Please remember to verify by going under your automobile the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them out from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last possibility 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 car, a pronounced fatigue 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 Volkswagen Multivan. To replace them go to your auto mechanic.
Other speed bump noise Volkswagen Multivan
If, even though all its assumptions, you still can’t find the origin of the noise your Volkswagen Multivan makes when you pass a speed bump, we encourage you to read this article on a loud noise on Volkswagen Multivan or to visit your technician in order to carry an in-depth check on your Volkswagen Multivan and identify this problem.
