Suspension cracking noise Audi Q7
Check Audi Q7 suspension
If you encounter a suspension noise when you pass a speed bump on your Audi Q7, and it is characterized by a “clack” or cracking, it is highly possible 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 concerns you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Audi Q7 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 amasses inside them their functions is deteriorated and it is possible to experience a sound 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 circumstances you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Audi Q7, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Audi Q7 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been damaged by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, place 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 supposed to endure you quite strongly over their entire travel. Keep in mind 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 Q7, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Please remember to check by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case remove them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a evident 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 Q7. To replace them go to your auto technician.
