Experiencing noises from your car frequently is never reassuring, so hearing noises on your Volkswagen ID.4 suspensions when you pass a speed bump can be stressing. This warning sign may be a sign of a minor issue as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to resolve the issue, it is with this goal in mind that we wanted to write this content to help 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 ID.4
Check Volkswagen ID.4 suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen ID.4, and it is characterized by a “clack” or cracking, it is highly possible 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 role during small bumps that compress the suspensions. To check if this is the issue that worries 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 fairly quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen ID.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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen ID.4, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen ID.4 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 change direction. If this is your situation, the parts 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, place it under the automobile and apply twists on each of its elements to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Volkswagen ID.4 to your auto mechanic or change 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 ID.4, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Please remember to check by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, 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 solve the issue.
Check engine silentblocks
Finally, last possibility 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 car, a pronounced fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Volkswagen ID.4. To change them go to your auto mechanic.
