Hearing noises from your auto often is never reassuring, so hearing noises on your Audi A5 suspensions when you pass a speed bump can be disturbing. This indicator may be a sign of a small issue 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 correct the issue, it is with this intention in mind that we wanted to write this content 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 reason 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 A5
Check Audi A5 suspension
If you encounter a suspension noise when you pass a speed bump on your Audi A5, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause 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 verify if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Audi A5 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is degraded and it is possible to experience a noise when they are in torsion.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 situations you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi A5, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Audi A5 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify direction. If this is the situation, the parts that may have been destroyed 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 verify it, place it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your technician or replace 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 A5, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks operate 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 happen that a squeaking noise appears when you pass a speed bumps or any holes with your Audi A5. To change them go to your auto mechanic.
Other speed bump noise Audi A5
If, despite all its assumptions, you still can’t uncover the origin of the noise your Audi A5 makes when you pass a speed bump, we advise you to consult this article on a loud noise on Audi A5 or to visit your technician in order to carry an in-depth check on your Audi A5 and determine this issue.
