Suspension cracking noise Volkswagen Polo 5
Check Volkswagen Polo 5 suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen Polo 5, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the problem that worries you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen Polo 5 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 degraded 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 situations you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Polo 5 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 vary direction. If this is the situation, the parts that may have been destroyed by usual 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 elements to check that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto mechanic or change them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Volkswagen Polo 5, 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. Remember to check by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last point 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 car, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Volkswagen Polo 5. To change them go to your auto mechanic.
