Listening noises from your automobile frequently is never comforting, so listening noises on your Mazda CX 5 suspensions when you go over a speed bump can be worrying. This indicator 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 solve the trouble, it is with this objective in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, 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 CX 5
Check Mazda CX 5 suspension
If you notice a suspension noise when you pass a speed bump on your Mazda CX 5, 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 role during small bumps that compress the suspensions. To verify if this is the trouble that concerns you, take a dented road and listen 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 fixes.
Check the cardan shaft
If you are here because you have researched for “Mazda CX 5 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Mazda CX 5 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 parts that may have been broken 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 verify it, position it under the automobile and apply twists on each of its elements to verify that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto technician 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 CX 5, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Remember to verify by going under your automobile the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Mazda CX 5. To swap them go to your mechanic.
