Finding out noises from your automobile regularly is never comforting, so discovering noises on your Mazda CX 7 suspensions when you pass a speed bump can be stressful. This warning sign may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the origin and take the necessary actions to eliminate the issue, it is with this aim 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 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 7
Check Mazda CX 7 suspension
If you experience a suspension noise when you pass a speed bump on your Mazda CX 7, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the issue that worries 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 maintenance.
Check the cardan shaft
If you are here because you have searched for “Mazda CX 7 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 builds up inside them their operation is deteriorated 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 turn at low speed. If it cracks in these two cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Mazda CX 7, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Mazda CX 7 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 situation, the components that may have been affected by normal 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 vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Mazda CX 7 to your auto mechanic or swap 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 pass a speed bump with your Mazda CX 7, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Remember to verify by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them off from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility 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 fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Mazda CX 7. To change them go to your mechanic.
Other speed bump noise Mazda CX 7
If, even though all its assumptions, you still can’t locate the origin of the noise your Mazda CX 7 makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Mazda CX 7 or to visit your auto mechanic in order to carry an in-depth check on your Mazda CX 7 and identify this issue.
