Discovering noises from your vehicle regularly is never reassuring, so discovering noises on your Toyota Aygo 2 suspensions when you go over a speed bump can be disturbing. This sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the cause and take the necessary actions to correct the issue, 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 Aygo 2
Check Toyota Aygo 2 suspension
If you notice a suspension noise when you pass a speed bump on your Toyota Aygo 2, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the issue that worries 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 replacing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Toyota Aygo 2 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get old and the dirt/dust builds up inside them their working is degraded 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 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 Toyota Aygo 2, don’t hesitate to check out this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Toyota Aygo 2 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the parts that may have been broken by normal 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 automobile and apply twists on each of its components 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 vehicle to your auto mechanic or swap 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 Toyota Aygo 2, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Remember to check by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them out from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last point 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 obvious fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Toyota Aygo 2. To swap them go to your auto mechanic.
Other speed bump noise Toyota Aygo 2
If, despite all its assumptions, you still can’t uncover the origin of the noise your Toyota Aygo 2 makes when you pass a speed bump, we suggest you to refer to this article on a loud noise on Toyota Aygo 2 or to visit your auto mechanic in order to carry an in-depth check on your Toyota Aygo 2 and determine this issue.
