Experiencing noises from your auto often is never comforting, so listening noises on your Volkswagen Tiguan suspensions when you pass a speed bump can be disturbing. This sign may be a sign of a minor trouble 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 solve the trouble, it is with this intention in mind that we wanted to write this article to help you see more clearly. We will first see the possible explanations 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 Tiguan
Check Volkswagen Tiguan suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Tiguan, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin 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 trouble that concerns you, take a dented road and focus on 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 auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen Tiguan 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Tiguan, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Volkswagen Tiguan passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is the case, the parts that may have been destroyed 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 verify it, place it under the automobile and apply twists on each of its elements to verify that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or swap them if they are involved.
squeaky noise speed bump Volkswagen Tiguan
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Tiguan, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Bear in mind to verify by going under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them out from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the auto, a noticable weakness of these will create 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 Tiguan. To change them go to your auto mechanic.
Other speed bump noise Volkswagen Tiguan
If, even though all its assumptions, you still can’t locate the source of the noise your Volkswagen Tiguan makes when you pass a speed bump, we suggest you to read this content on a loud noise on Volkswagen Tiguan or to visit your auto technician in order to carry an in-depth check on your Volkswagen Tiguan and identify this trouble.
