Discovering noises from your car often is never comforting, so hearing noises on your Volkswagen Coccinelle suspensions when you pass a speed bump can be disturbing. This indicator may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to correct the trouble, 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 Coccinelle
Check Volkswagen Coccinelle suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen Coccinelle, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them fairly quickly 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 Coccinelle 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 old and the dirt/dust accumulates inside them their functions 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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Coccinelle, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Volkswagen Coccinelle passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is your situation, the parts that may have been affected by usual 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, put it under the vehicle and apply twists on each of its components to check that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your Volkswagen Coccinelle to your auto technician or change them if they are involved.
squeaky noise speed bump Volkswagen Coccinelle
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Coccinelle, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Please remember to check by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case remove them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a evident weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Volkswagen Coccinelle. To change them go to your technician.
Other speed bump noise Volkswagen Coccinelle
If, even though all its assumptions, you still can’t find the source of the noise your Volkswagen Coccinelle makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Volkswagen Coccinelle or to visit your auto technician in order to carry an in-depth check on your Volkswagen Coccinelle and determine this trouble.
