Finding out noises from your automobile regularly is never reassuring, so listening noises on your Audi Q8 suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a insignificant issue 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 issue, 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 reasons for a crack when the speed bump passes, after that, 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 Q8
Check Audi Q8 suspension
If you experience a suspension noise when you pass a speed bump on your Audi Q8, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 issue that worries you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them as soon as possible or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Audi Q8 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi Q8, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Audi Q8 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 your situation, the components that may have been affected 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 check it, put 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. Keep in mind to take your Audi Q8 to your auto mechanic 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 go over a speed bump with your Audi Q8, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Remember to check by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the automobile, a evident fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Audi Q8. To replace them go to your mechanic.
Other speed bump noise Audi Q8
If, even though all its assumptions, you still can’t find the origin of the noise your Audi Q8 makes when you pass a speed bump, we suggest you to read this article on a loud noise on Audi Q8 or to visit your auto mechanic in order to carry an in-depth check on your Audi Q8 and determine this issue.
