Listening noises from your car regularly is never comforting, so hearing noises on your Toyota Prius 2 suspensions when you pass a speed bump can be stressful. This sign may be a sign of a small trouble as well as a warning of a much larger repair to come. In any case, it is important to check the cause and take the necessary actions to resolve the trouble, it is with this objective in mind that we wanted to write this content to help you see more clearly. We will first see the possible causes 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 Toyota Prius 2
Check Toyota Prius 2 suspension
If you notice a suspension noise when you pass a speed bump on your Toyota Prius 2, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 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 go over holes. If it is indeed the cups, think of changing them as soon as possible or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Toyota Prius 2 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Prius 2, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Toyota Prius 2 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 modify direction. If this is the 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 causes of your noises, to examine it, place it under the car and apply twists on each of its components to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your Toyota Prius 2 to your technician or swap 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 Prius 2, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Remember to examine 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 out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will generate 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 Toyota Prius 2. To change them go to your auto technician.
Other speed bump noise Toyota Prius 2
If, even though all its assumptions, you still can’t uncover the origin of the noise your Toyota Prius 2 makes when you pass a speed bump, we encourage you to read this article on a loud noise on Toyota Prius 2 or to visit your technician in order to carry an in-depth check on your Toyota Prius 2 and discover this trouble.
