Suspension cracking noise Toyota Yaris

Check Toyota Yaris suspension

If you encounter a suspension noise when you pass a speed bump on your Toyota Yaris, 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 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 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 swapping them as soon as possible or you may ruin other parts and have to make more important fixes.

Check the cardan shaft

If you are here because you have researched for “Toyota Yaris 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 circumstances you should consider swapping it or them.

Check steering hinges/stabilizer bar

Finally, when you experience a suspension noise when your Toyota Yaris 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 components that may have been destroyed 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 check it, place it under the car and apply twists on each of its elements to check that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic 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 Yaris, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Bear in mind to check by going under your car the condition of the paint on your bar which will tell us if there is friction. Second possible 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 fix the issue.

Check engine silentblocks

Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable 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 Yaris. To change them go to your mechanic.
