Discovering noises from your vehicle regularly is never comforting, so listening noises on your Volkswagen Polo 6 suspensions when you pass a speed bump can be worrying. This warning 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 correct the issue, it is with this aim in mind that we wanted to write this content to help you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, then, 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 Volkswagen Polo 6
Check Volkswagen Polo 6 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Polo 6, 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 dead, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role 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 circulate over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Polo 6 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Polo 6, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Polo 6 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 adjust direction. If this is the situation, the parts that may have been broken by normal 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, place it under the vehicle and apply twists on each of its components to check that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician 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 pass a speed bump with your Volkswagen Polo 6, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Bear in mind 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 take them off from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case that we can check 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 noticable weakness of these will make 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 Volkswagen Polo 6. To swap them go to your auto mechanic.
