Suspension cracking noise Toyota Yaris 3

Check Toyota Yaris 3 suspension

If you experience a suspension noise when you pass a speed bump on your Toyota Yaris 3, and it is characterized 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 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 function during small bumps that compress the suspensions. To verify if this is the issue that worries 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 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 searched for “Toyota Yaris 3 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 accumulates inside them their action is degraded and it is possible to experience a noise when they are in torsion. To verify 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 replacing it or them. If you have the feeling that this noise is more like a a loud noise on Toyota Yaris 3, don’t hesitate to read this document.

Check steering hinges/stabilizer bar

Finally, when you find out a suspension noise when your Toyota Yaris 3 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 change direction. If this is your situation, the components that may have been destroyed 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 verify it, place it under the automobile and apply twists on each of its elements to verify that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your Toyota Yaris 3 to your auto technician or change 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 Yaris 3, 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 generate this squeaking noise. Bear in mind to verify by going under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them out from the cradle and grease them, this should eliminate the issue.

Check engine silentblocks

Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the automobile, a noticable weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Toyota Yaris 3. To swap them go to your mechanic.
