Discovering noises from your car often is never reassuring, so hearing noises on your Toyota C-hr suspensions when you pass a speed bump can be stressing. 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 origin and take the necessary actions to solve the problem, it is with this aim in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 C-hr
Check Toyota C-hr suspension
If you notice a suspension noise when you pass a speed bump on your Toyota C-hr, and it is categorized 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 job during small bumps that compress the suspensions. To examine 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 changing them fairly quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Toyota C-hr 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Toyota C-hr, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Toyota C-hr passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is your situation, the parts that may have been broken 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 examine it, put 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 expected to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your mechanic or swap them if they are involved.
squeaky noise speed bump Toyota C-hr
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Toyota C-hr, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Remember to examine by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case disassemble them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, 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 occurs when you pass a speed bumps or any holes with your Toyota C-hr. To change them go to your auto mechanic.
Other speed bump noise Toyota C-hr
If, despite all its assumptions, you still can’t locate the source of the noise your Toyota C-hr makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Toyota C-hr or to visit your mechanic in order to carry an in-depth check on your Toyota C-hr and find this problem.
