Listening noises from your auto frequently is never reassuring, so discovering noises on your Volkswagen CC suspensions when you go over 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. Whatever the case, it is fundamental to check the source and take the necessary actions to resolve the trouble, it is with this goal in mind that we wanted to write this article 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 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 CC
Check Volkswagen CC suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen CC, and it is categorized 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 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 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 changing them quickly or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen CC 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 old and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise 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 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 CC, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen CC 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 adjust direction. If this is the case, the parts that may have been damaged 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 examine it, position it under the automobile and apply twists on each of its components to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your Volkswagen CC to your auto technician 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 go over a speed bump with your Volkswagen CC, 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 create this squeaking noise. Keep in mind to examine by going under your automobile 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 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 auto, a noticable weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Volkswagen CC. To swap them go to your auto mechanic.
Other speed bump noise Volkswagen CC
If, despite all its assumptions, you still can’t uncover the origin of the noise your Volkswagen CC makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Volkswagen CC or to visit your auto technician in order to carry an in-depth check on your Volkswagen CC and determine this trouble.
