Listening noises from your auto often is never comforting, so hearing noises on your Volkswagen Jetta 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 necessary to check the source and take the necessary actions to eliminate the trouble, it is with this intention 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, then, 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 Jetta
Check Volkswagen Jetta suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Jetta, and it is characterized by a “clack” or cracking, it is highly plausible 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 drive over holes. If it is indeed the cups, think of replacing them fairly quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen Jetta 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Jetta, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Volkswagen Jetta passes over a speed bumps, it is imaginable 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 the situation, the components 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 check it, place it under the car and apply twists on each of its elements to check that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your Volkswagen Jetta to your auto technician or change them if they are involved.
squeaky noise speed bump Volkswagen Jetta
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 Jetta, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Please remember to check by passing under your car 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 resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Volkswagen Jetta. To replace them go to your mechanic.
Other speed bump noise Volkswagen Jetta
If, even though all its assumptions, you still can’t find the source of the noise your Volkswagen Jetta makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Volkswagen Jetta or to visit your auto technician in order to carry an in-depth check on your Volkswagen Jetta and identify this trouble.
