Finding out noises from your automobile frequently is never comforting, so discovering noises on your Mazda Mx5 suspensions when you go over a speed bump can be disturbing. This indicator may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to correct the trouble, it is with this intention in mind that we wanted to write this document 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 cause 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 Mx5
Check Mazda Mx5 suspension
If you encounter a suspension noise when you pass a speed bump on your Mazda Mx5, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 verify if this is the trouble that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Mazda Mx5 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 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 Mazda Mx5, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Mazda Mx5 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the case, the parts 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 causes of your noises, to verify it, place it under the car and apply twists on each of its elements to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Mazda Mx5 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 go over a speed bump with your Mazda Mx5, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Bear in mind to verify by going under your car 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 provoke 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 verify together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a noticable fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Mazda Mx5. To change them go to your auto technician.
Other speed bump noise Mazda Mx5
If, even though all its assumptions, you still can’t uncover the origin of the noise your Mazda Mx5 makes when you pass a speed bump, we recommend you to read this article on a loud noise on Mazda Mx5 or to visit your auto mechanic in order to carry an in-depth check on your Mazda Mx5 and identify this trouble.
