Discovering noises from your car regularly is never comforting, so discovering noises on your Volkswagen Fox suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a small problem as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to solve the problem, it is with this aim in mind that we wanted to write this document 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 Fox
Check Volkswagen Fox suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Fox, 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 old, 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 verify if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping 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 Fox 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 builds up inside them their functions is degraded and it is possible to experience a noise when they are in torsion. To verify 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Fox, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Fox passes over a speed bumps, it is plausible 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 the situation, the parts that may have been broken 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 verify it, put it under the car and apply twists on each of its elements to verify that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your Volkswagen Fox to your auto technician or change them if they are involved.
squeaky noise speed bump Volkswagen Fox
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 Fox, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Please remember to verify by going under your car 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 dried out and create noise, in which case take them out from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a noticable weakness of these will generate 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 Fox. To change them go to your mechanic.
Other speed bump noise Volkswagen Fox
If, even though all its assumptions, you still can’t find the source of the noise your Volkswagen Fox makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Volkswagen Fox or to visit your auto technician in order to carry an in-depth check on your Volkswagen Fox and discover this problem.
