Discovering noises from your car frequently is never reassuring, so listening noises on your Volkswagen Touran suspensions when you go over 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 resolve the problem, it is with this aim in mind that we wanted to write this content to support you see more clearly. We will first see the possible causes 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 Touran
Check Volkswagen Touran suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Touran, 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 dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the problem 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 repairs.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Touran 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a sound when they are in torsion. To check 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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Touran, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Touran passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the parts 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 check it, position it under the vehicle and apply twists on each of its elements to check that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your Volkswagen Touran to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Volkswagen Touran
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Volkswagen Touran, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Bear in mind to check by going under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them out from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Volkswagen Touran. To replace them go to your technician.
Other speed bump noise Volkswagen Touran
If, even though all its assumptions, you still can’t uncover the origin of the noise your Volkswagen Touran makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Volkswagen Touran or to visit your auto mechanic in order to carry an in-depth check on your Volkswagen Touran and determine this problem.
