Listening noises from your auto regularly is never reassuring, so listening noises on your Audi S3 suspensions when you pass a speed bump can be stressful. This indicator 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 essential to check the source and take the necessary actions to correct the trouble, it is with this objective in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons 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 Audi S3
Check Audi S3 suspension
If you encounter a suspension noise when you pass a speed bump on your Audi S3, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 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 fairly quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Audi S3 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 old and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a sound 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 situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Audi S3, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Audi S3 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 adjust direction. If this is your 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 causes of your noises, to check it, position it under the vehicle and apply twists on each of its elements to check that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Audi S3 to your technician or swap them if they are involved.
squeaky noise speed bump Audi S3
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Audi S3, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind to check by going under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them out from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can check 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 evident 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 Audi S3. To change them go to your technician.
Other speed bump noise Audi S3
If, despite all its assumptions, you still can’t find the source of the noise your Audi S3 makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Audi S3 or to visit your technician in order to carry an in-depth check on your Audi S3 and find this trouble.
