Finding out noises from your vehicle frequently is never reassuring, so hearing noises on your Mazda CX 9 suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a minor trouble as well as a warning of a much larger repair to come. In any case, it is essential to check the cause and take the necessary actions to eliminate the trouble, it is with this intention in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, 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 CX 9
Check Mazda CX 9 suspension
If you notice a suspension noise when you pass a speed bump on your Mazda CX 9, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 go over holes. If it is indeed the cups, think of swapping them quickly 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 “Mazda CX 9 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 make a 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 CX 9, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Mazda CX 9 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 the case, the components that may have been damaged by normal 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 car 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 Mazda CX 9 to your auto mechanic or swap them if they are involved.
squeaky noise speed bump Mazda CX 9
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Mazda CX 9, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Keep in mind to examine by passing under your car 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 bring on noise, in which case remove them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case 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 pronounced fatigue of these will create 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 CX 9. To replace them go to your mechanic.
Other speed bump noise Mazda CX 9
If, despite all its assumptions, you still can’t find the source of the noise your Mazda CX 9 makes when you pass a speed bump, we advise you to read this content on a loud noise on Mazda CX 9 or to visit your auto mechanic in order to carry an in-depth check on your Mazda CX 9 and determine this trouble.
