Experiencing noises from your vehicle regularly is never comforting, so listening noises on your Audi Q3 suspensions when you go over a speed bump can be stressing. This warning sign 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 source and take the necessary actions to correct the problem, it is with this objective 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 Q3
Check Audi Q3 suspension
If you encounter a suspension noise when you pass a speed bump on your Audi Q3, and it is characterized 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 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 function during small bumps that compress the suspensions. To verify if this is the problem 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 changing them quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have searched for “Audi Q3 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Audi Q3, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Audi Q3 passes over a speed bumps, it is imaginable 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 the situation, the parts that may have been affected 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 verify it, position it under the automobile and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your vehicle 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 Q3, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Please remember to verify by going under your automobile the condition of the paint on your bar which will tell us if there is friction. Second plausible point, 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 eliminate 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 vehicle, a pronounced fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Audi Q3. To replace them go to your technician.
Other speed bump noise Audi Q3
If, even though all its assumptions, you still can’t locate the source of the noise your Audi Q3 makes when you pass a speed bump, we advise you to consult this article on a loud noise on Audi Q3 or to visit your auto mechanic in order to carry an in-depth check on your Audi Q3 and find this problem.
