Hearing noises from your automobile often is never reassuring, so listening noises on your Volkswagen Transporter suspensions when you go over a speed bump can be worrying. This sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the source and take the necessary actions to eliminate the problem, it is with this goal in mind that we wanted to write this document 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 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 Transporter
Check Volkswagen Transporter suspension
If you experience a suspension noise when you pass a speed bump on your Volkswagen Transporter, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 examine 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 quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Volkswagen Transporter 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 amasses inside them their functions is degraded and it is possible to experience a sound when they are in torsion. To examine 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 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 Transporter, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Volkswagen Transporter passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the parts that may have been affected by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, position it under the car and apply twists on each of its components to examine that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your Volkswagen Transporter to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Volkswagen Transporter
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 Transporter, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Please remember to examine by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, 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 Transporter. To swap them go to your auto technician.
Other speed bump noise Volkswagen Transporter
If, even though all its assumptions, you still can’t find the origin of the noise your Volkswagen Transporter makes when you pass a speed bump, we encourage you to consult this content on a loud noise on Volkswagen Transporter or to visit your auto mechanic in order to carry an in-depth check on your Volkswagen Transporter and determine this problem.
