Suspension cracking noise PORSCHE 718
Check PORSCHE 718 suspension
If you experience a suspension noise when you pass a speed bump on your PORSCHE 718, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 circulate over holes. If it is indeed the cups, think of swapping them as soon as possible or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have searched for “PORSCHE 718 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your PORSCHE 718 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 the case, the components that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, place it under the automobile and apply twists on each of its components to check that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your PORSCHE 718 to your auto technician or replace them if they are involved.

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 PORSCHE 718, it is possible 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 passing under your automobile the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case disassemble them from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last case 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 vehicle, 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 comes up when you pass a speed bumps or any holes with your PORSCHE 718. To replace them go to your technician.

If, despite all its assumptions, you still can’t uncover the origin of the noise your PORSCHE 718 makes when you pass a speed bump, we recommend you to read this article on a loud noise on PORSCHE 718 or to visit your auto technician in order to carry an in-depth check on your PORSCHE 718 and identify this trouble.
