Discovering noises from your auto frequently is never comforting, so hearing noises on your Audi A6 suspensions when you pass a speed bump can be worrying. This sign may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the source and take the necessary actions to solve the issue, it is with this goal in mind that we wanted to write this article to support 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 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 A6
Check Audi A6 suspension
If you experience a suspension noise when you pass a speed bump on your Audi A6, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 examine if this is the issue that concerns 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 quickly 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 A6 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 old and the dirt/dust accumulates inside them their working is deteriorated and it is possible to experience a noise when they are in torsion. To examine 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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi A6, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Audi A6 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 change direction. If this is your situation, the parts that may have been damaged 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 examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic 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 A6, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Bear in mind to examine by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, 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 shows up when you pass a speed bumps or any holes with your Audi A6. To change them go to your mechanic.
Other speed bump noise Audi A6
If, even though all its assumptions, you still can’t uncover the source of the noise your Audi A6 makes when you pass a speed bump, we suggest you to read this article on a loud noise on Audi A6 or to visit your auto mechanic in order to carry an in-depth check on your Audi A6 and determine this issue.
