Listening noises from your automobile regularly is never comforting, so discovering noises on your Volkswagen Scirocco suspensions when you go over a speed bump can be worrying. 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 essential to check the origin and take the necessary actions to solve the trouble, it is with this goal in mind that we wanted to write this document 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 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 Scirocco
Check Volkswagen Scirocco suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Scirocco, 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 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 check if this is the trouble that worries you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen Scirocco 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Scirocco, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Volkswagen Scirocco passes over a speed bumps, it is plausible 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 the situation, the parts that may have been affected by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, place it under the automobile and apply twists on each of its elements to check 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 mechanic or change them if they are involved.
squeaky noise speed bump Volkswagen Scirocco
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 Scirocco, 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 generate this squeaking noise. Bear in mind to check by going under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Volkswagen Scirocco. To change them go to your auto mechanic.
Other speed bump noise Volkswagen Scirocco
If, despite all its assumptions, you still can’t find the source of the noise your Volkswagen Scirocco makes when you pass a speed bump, we recommend you to refer to this article on a loud noise on Volkswagen Scirocco or to visit your mechanic in order to carry an in-depth check on your Volkswagen Scirocco and discover this trouble.
