Experiencing noises from your auto regularly is never reassuring, so listening noises on your Tesla Model S suspensions when you pass a speed bump can be disturbing. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the source and take the necessary actions to eliminate the trouble, it is with this objective in mind that we wanted to write this article to help you see more clearly. We will first see the possible causes 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 Tesla Model S
Check Tesla Model S suspension
If you notice a suspension noise when you pass a speed bump on your Tesla Model S, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 examine if this is the trouble 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 changing 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 looked for for “Tesla Model S 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Tesla Model S, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Tesla Model S passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the situation, the parts 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 origins of your noises, to examine it, put it under the car and apply twists on each of its elements to examine that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or swap them if they are involved.
squeaky noise speed bump Tesla Model S
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Tesla Model S, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Bear in mind to examine 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 dried out and create noise, in which case disassemble them from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, 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 appears when you pass a speed bumps or any holes with your Tesla Model S. To swap them go to your mechanic.
Other speed bump noise Tesla Model S
If, even though all its assumptions, you still can’t uncover the source of the noise your Tesla Model S makes when you pass a speed bump, we suggest you to read this content on a loud noise on Tesla Model S or to visit your mechanic in order to carry an in-depth check on your Tesla Model S and determine this trouble.
