Discovering noises from your car regularly is never comforting, so hearing noises on your PORSCHE BOXSTER suspensions when you pass a speed bump can be stressful. This sign 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 resolve the trouble, it is with this goal in mind that we wanted to write this article to help 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 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 PORSCHE BOXSTER
Check PORSCHE BOXSTER suspension
If you encounter a suspension noise when you pass a speed bump on your PORSCHE BOXSTER, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the trouble that concerns 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 replacing them fairly quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “PORSCHE BOXSTER 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 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 PORSCHE BOXSTER, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your PORSCHE BOXSTER passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary 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 verify it, position it under the vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or replace them if they are involved.
squeaky noise speed bump PORSCHE BOXSTER
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 PORSCHE BOXSTER, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Bear in mind to verify by passing under your vehicle the condition of the paint on your bar which will reveal 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 remove them from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a evident fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your PORSCHE BOXSTER. To change them go to your technician.
Other speed bump noise PORSCHE BOXSTER
If, despite all its assumptions, you still can’t uncover the source of the noise your PORSCHE BOXSTER makes when you pass a speed bump, we advise you to consult this content on a loud noise on PORSCHE BOXSTER or to visit your auto technician in order to carry an in-depth check on your PORSCHE BOXSTER and determine this trouble.
