Discovering noises from your car often is never comforting, so hearing noises on your Volkswagen Golf 4 suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to eliminate the issue, it is with this aim in mind that we wanted to write this content 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 Volkswagen Golf 4
Check Volkswagen Golf 4 suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Golf 4, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, 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 job during small bumps that compress the suspensions. To check if this is the issue 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 changing them quickly or you may damage other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen Golf 4 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Golf 4, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Golf 4 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 vary direction. If this is the situation, the parts that may have been affected by regular 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 special play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Golf 4, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Bear in mind to check by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible point, 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 issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Volkswagen Golf 4. To swap them go to your auto mechanic.
Other speed bump noise Volkswagen Golf 4
If, despite all its assumptions, you still can’t find the origin of the noise your Volkswagen Golf 4 makes when you pass a speed bump, we encourage you to refer to this content on a loud noise on Volkswagen Golf 4 or to visit your auto mechanic in order to carry an in-depth check on your Volkswagen Golf 4 and find this issue.
