Listening noises from your car regularly is never reassuring, so discovering noises on your Volkswagen Crafter 2 suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a minor trouble 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 eliminate the trouble, it is with this intention in mind that we wanted to write this content to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, after that, what can be the reason 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 Crafter 2
Check Volkswagen Crafter 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Crafter 2, 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 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 check if this is the trouble that concerns you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Volkswagen Crafter 2 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 amasses inside them their operation 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Crafter 2, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Volkswagen Crafter 2 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the components 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 causes of your noises, to check it, position it under the automobile and apply twists on each of its components to check that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Volkswagen Crafter 2, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate 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 plausible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks function 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 occurs when you pass a speed bumps or any holes with your Volkswagen Crafter 2. To replace them go to your technician.
Other speed bump noise Volkswagen Crafter 2
If, despite all its assumptions, you still can’t find the origin of the noise your Volkswagen Crafter 2 makes when you pass a speed bump, we suggest you to refer to this article on a loud noise on Volkswagen Crafter 2 or to visit your technician in order to carry an in-depth check on your Volkswagen Crafter 2 and determine this trouble.
