Finding out noises from your automobile regularly is never reassuring, so listening noises on your Volkswagen Touran 3 suspensions when you go over a speed bump can be disturbing. This indicator 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 goal 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, after that, 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 Volkswagen Touran 3
Check Volkswagen Touran 3 suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen Touran 3, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, 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 function during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of changing them as soon as possible or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Touran 3 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 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 Volkswagen Touran 3, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Volkswagen Touran 3 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you vary direction. If this is the case, 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 origins of your noises, to verify it, place it under the vehicle and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your Volkswagen Touran 3 to your 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 Volkswagen Touran 3, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Bear in mind to verify by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks work 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 appear that a squeaking noise appears when you pass a speed bumps or any holes with your Volkswagen Touran 3. To change them go to your auto technician.
Other speed bump noise Volkswagen Touran 3
If, despite all its assumptions, you still can’t locate the origin of the noise your Volkswagen Touran 3 makes when you pass a speed bump, we encourage you to read this content on a loud noise on Volkswagen Touran 3 or to visit your technician in order to carry an in-depth check on your Volkswagen Touran 3 and determine this problem.
