Discovering noises from your vehicle regularly is never comforting, so listening noises on your Mazda 3 suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to correct the trouble, 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 explanations 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 Mazda 3
Check Mazda 3 suspension
If you experience a suspension noise when you pass a speed bump on your Mazda 3, 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 function during small bumps that compress the suspensions. To examine if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Mazda 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Mazda 3, don’t hesitate to check out this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Mazda 3 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the components that may have been affected 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, place it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are supposed to resist 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.
squeaky noise speed bump Mazda 3
Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Mazda 3, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Bear in mind to examine by going under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the vehicle, 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 Mazda 3. To change them go to your auto technician.

If, despite all its assumptions, you still can’t find the source of the noise your Mazda 3 makes when you pass a speed bump, we encourage you to refer to this article on a loud noise on Mazda 3 or to visit your auto mechanic in order to carry an in-depth check on your Mazda 3 and find this trouble.
