Experiencing noises from your automobile frequently is never reassuring, so listening noises on your Volkswagen Routan suspensions when you pass a speed bump can be disturbing. This indicator may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is important to check the cause and take the necessary actions to solve the trouble, it is with this objective in mind that we wanted to write this document 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 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 Routan
Check Volkswagen Routan suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Routan, and it is characterized by a “clack” or cracking, it is highly plausible 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 role during small bumps that compress the suspensions. To examine if this is the trouble that worries 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 swapping them quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Routan 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is deteriorated and it is possible to experience a sound when they are in torsion. To examine 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 Routan, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen Routan 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 vary direction. If this is the situation, the components 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 examine it, position it under the car and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Volkswagen Routan to your technician or replace them if they are involved.
squeaky noise speed bump Volkswagen Routan
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 Routan, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to examine by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case remove them from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can examine 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 evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Volkswagen Routan. To replace them go to your auto mechanic.
Other speed bump noise Volkswagen Routan
If, even though all its assumptions, you still can’t locate the source of the noise your Volkswagen Routan makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Volkswagen Routan or to visit your technician in order to carry an in-depth check on your Volkswagen Routan and discover this trouble.
