Listening noises from your automobile often is never comforting, so hearing noises on your Audi Rs4 suspensions when you go over a speed bump can be disturbing. This symptom may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to resolve the problem, 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 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 Rs4
Check Audi Rs4 suspension
If you experience a suspension noise when you pass a speed bump on your Audi Rs4, and it is categorized 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 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 problem that worries you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Audi Rs4 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 Audi Rs4, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Audi Rs4 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 modify direction. If this is the situation, the parts that may have been broken 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 car and apply twists on each of its elements to check 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 vehicle to your mechanic 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 Audi Rs4, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Remember to check by going under your car the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last case that we can check 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 pronounced fatigue of these will generate 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 Audi Rs4. To change them go to your auto technician.
Other speed bump noise Audi Rs4
If, despite all its assumptions, you still can’t uncover the origin of the noise your Audi Rs4 makes when you pass a speed bump, we advise you to read this content on a loud noise on Audi Rs4 or to visit your mechanic in order to carry an in-depth check on your Audi Rs4 and identify this problem.
