Hearing noises from your automobile regularly is never reassuring, so hearing noises on your Volkswagen Crafter suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the origin and take the necessary actions to eliminate the problem, 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 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
Check Volkswagen Crafter suspension
If you notice a suspension noise when you pass a speed bump on your Volkswagen Crafter, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 problem that worries you, take a dented road and listen to 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 affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen Crafter 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 operation is degraded and it is possible to experience a noise 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 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 Crafter, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Volkswagen Crafter 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 vary direction. If this is the case, the parts that may have been broken by usual 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, position 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 expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician or replace them if they are involved.
squeaky noise speed bump Volkswagen Crafter
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 Crafter, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Remember to check by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them off from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced fatigue of these will generate 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 Crafter. To change them go to your auto technician.
Other speed bump noise Volkswagen Crafter
If, despite all its assumptions, you still can’t uncover the origin of the noise your Volkswagen Crafter makes when you pass a speed bump, we encourage you to refer to this content on a loud noise on Volkswagen Crafter or to visit your auto technician in order to carry an in-depth check on your Volkswagen Crafter and determine this problem.
