Hearing noises from your car regularly is never comforting, so listening noises on your Audi R8 suspensions when you pass a speed bump can be stressful. This symptom may be a sign of a small problem as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to eliminate the problem, it is with this goal in mind that we wanted to write this document to support 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 R8
Check Audi R8 suspension
If you notice a suspension noise when you pass a speed bump on your Audi R8, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 function during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them as soon as possible or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Audi R8 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion. To verify 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 circumstances you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi R8, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Audi R8 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 change direction. If this is the case, the components that may have been broken by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, position it under the automobile and apply twists on each of its elements to verify that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Audi R8, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Bear in mind to verify by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a evident fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Audi R8. To change them go to your mechanic.
Other speed bump noise Audi R8
If, even though all its assumptions, you still can’t uncover the origin of the noise your Audi R8 makes when you pass a speed bump, we encourage you to refer to this content on a loud noise on Audi R8 or to visit your auto technician in order to carry an in-depth check on your Audi R8 and determine this problem.
