Hearing noises from your auto often is never reassuring, so hearing noises on your Toyota Yaris 2 suspensions when you go over a speed bump can be stressful. This sign may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. In any case, it is fundamental to check the source and take the necessary actions to resolve the trouble, it is with this objective in mind that we wanted to write this document to support 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 Yaris 2
Check Toyota Yaris 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Toyota Yaris 2, and it is characterized by a “clack” or cracking, it is highly possible 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 check if this is the trouble that concerns you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Toyota Yaris 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 old 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 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 turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Yaris 2, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Toyota Yaris 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 vary direction. If this is the situation, the components that may have been damaged by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, place it under the vehicle and apply twists on each of its elements to check that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Toyota Yaris 2 to your mechanic or change them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Toyota Yaris 2, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Keep in mind to check by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a evident 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 Yaris 2. To swap them go to your mechanic.
Other speed bump noise Toyota Yaris 2
If, even though all its assumptions, you still can’t locate the origin of the noise your Toyota Yaris 2 makes when you pass a speed bump, we suggest you to refer to this article on a loud noise on Toyota Yaris 2 or to visit your mechanic in order to carry an in-depth check on your Toyota Yaris 2 and determine this trouble.
