Listening noises from your automobile regularly is never reassuring, so listening noises on your Volkswagen Touareg suspensions when you go over a speed bump can be stressing. This indicator may be a sign of a minor trouble 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 eliminate the trouble, it is with this intention 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, then, 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 Touareg
Check Volkswagen Touareg suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Touareg, and it is characterized 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 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 verify if this is the trouble that worries you, take a dented road and focus on the noise coming from your front axle as you circulate 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 auto repairs.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Touareg 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 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 Touareg, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen Touareg passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is your situation, the parts that may have been broken by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, put 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 expected to resist you quite strongly over their entire travel. Please remember to take your vehicle 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 Touareg, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Keep in mind to verify by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case disassemble them from the cradle and grease them, this should resolve the trouble.
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 noticable weakness 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 Volkswagen Touareg. To change them go to your mechanic.
Other speed bump noise Volkswagen Touareg
If, despite all its assumptions, you still can’t find the source of the noise your Volkswagen Touareg makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Volkswagen Touareg or to visit your technician in order to carry an in-depth check on your Volkswagen Touareg and determine this trouble.
