Experiencing noises from your vehicle regularly is never reassuring, so discovering noises on your Volkswagen Touran 2 suspensions when you pass a speed bump can be worrying. This sign may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is important to check the cause and take the necessary actions to correct the issue, it is with this intention in mind that we wanted to write this article to support 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 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 2
Check Volkswagen Touran 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Touran 2, and it is characterized by a “clack” or cracking, it is highly plausible 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 role during small bumps that compress the suspensions. To verify if this is the issue that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them fairly quickly 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 2 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions 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 2, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Volkswagen Touran 2 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 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 components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Touran 2, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Please remember to verify by passing under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point 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 vehicle, a pronounced fatigue of these will create 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 Volkswagen Touran 2. To change them go to your mechanic.
Other speed bump noise Volkswagen Touran 2
If, even though all its assumptions, you still can’t uncover the origin of the noise your Volkswagen Touran 2 makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Volkswagen Touran 2 or to visit your mechanic in order to carry an in-depth check on your Volkswagen Touran 2 and find this issue.
