Listening noises from your automobile regularly is never comforting, so hearing noises on your Audi A7 suspensions when you go over a speed bump can be stressing. 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 essential to check the origin and take the necessary actions to correct the problem, it is with this intention in mind that we wanted to write this document to help you see more clearly. We will first see the possible causes for a crack when the speed bump passes, after that, 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 A7
Check Audi A7 suspension
If you notice a suspension noise when you pass a speed bump on your Audi A7, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 go 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 vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Audi A7 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Audi A7, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Audi A7 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the parts 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 origins of your noises, to check it, put it under the vehicle and apply twists on each of its components to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic or swap them if they are involved.
squeaky noise speed bump Audi A7
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 A7, 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 generate this squeaking noise. Remember to check by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them off from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a noticable weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Audi A7. To replace them go to your auto technician.
Other speed bump noise Audi A7
If, despite all its assumptions, you still can’t uncover the origin of the noise your Audi A7 makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Audi A7 or to visit your auto mechanic in order to carry an in-depth check on your Audi A7 and find this problem.
