Listening noises from your vehicle often is never reassuring, so discovering noises on your Volkswagen Beetle suspensions when you go over a speed bump can be disturbing. This symptom may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is important to check the source and take the necessary actions to resolve the problem, it is with this intention in mind that we wanted to write this article 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 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 Beetle
Check Volkswagen Beetle suspension
If you encounter a suspension noise when you pass a speed bump on your Volkswagen Beetle, 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 dead, 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 verify if this is the problem that concerns you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Volkswagen Beetle 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion. To verify 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 replacing it or them. If you have the feeling that this noise is more like a a loud noise on Volkswagen Beetle, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Volkswagen Beetle 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 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 verify it, place it under the vehicle and apply twists on each of its components to verify 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 Beetle to your mechanic or replace them if they are involved.
squeaky noise speed bump Volkswagen Beetle
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 Beetle, 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 generate this squeaking noise. Keep in mind to verify by passing under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Volkswagen Beetle. To swap them go to your auto technician.
Other speed bump noise Volkswagen Beetle
If, even though all its assumptions, you still can’t find the origin of the noise your Volkswagen Beetle makes when you pass a speed bump, we encourage you to read this content on a loud noise on Volkswagen Beetle or to visit your mechanic in order to carry an in-depth check on your Volkswagen Beetle and determine this problem.
