Suspension cracking noise Volkswagen Polo 3
Check Volkswagen Polo 3 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Polo 3, and it is categorized 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass 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 vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Polo 3 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 operation 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 replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen Polo 3 passes over a speed bumps, it is possible 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 destroyed 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, position it under the car and apply twists on each of its components to check that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or change 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 3, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to check by going under your car the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Volkswagen Polo 3. To change them go to your auto mechanic.
