Listening noises from your automobile frequently is never comforting, so listening noises on your Toyota Scion FR S suspensions when you pass a speed bump can be worrying. This indicator may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to solve the problem, it is with this aim in mind that we wanted to write this article to support you see more clearly. We will first see the possible causes for a crack when the speed bump passes, then, 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 Toyota Scion FR S
Check Toyota Scion FR S suspension
If you experience a suspension noise when you pass a speed bump on your Toyota Scion FR S, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are old, 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 problem that worries 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 swapping them as soon as possible or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Toyota Scion FR 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Scion FR S, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Toyota Scion FR S passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change 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 causes of your noises, to verify it, place it under the car and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Toyota Scion FR S to your auto technician or replace them if they are involved.

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 Toyota Scion FR S, 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 cause this squeaking noise. Please remember to verify by going under your car 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 cause noise, in which case take them off from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Toyota Scion FR S. To replace them go to your technician.
Other speed bump noise Toyota Scion FR S
If, despite all its assumptions, you still can’t locate the source of the noise your Toyota Scion FR S makes when you pass a speed bump, we encourage you to consult this content on a loud noise on Toyota Scion FR S or to visit your auto technician in order to carry an in-depth check on your Toyota Scion FR S and identify this problem.
