Listening noises from your automobile regularly is never reassuring, so listening noises on your Mazda 6 suspensions when you pass a speed bump can be stressing. This symptom may be a sign of a small 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 objective in mind that we wanted to write this document to support 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 6
Check Mazda 6 suspension
If you notice a suspension noise when you pass a speed bump on your Mazda 6, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 examine if this is the issue that concerns you, take a dented road and focus on the noise coming from your front axle as you pass 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 maintenance.
Check the cardan shaft
If you are here because you have researched for “Mazda 6 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Mazda 6, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Mazda 6 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 vary direction. If this is the case, the parts that may have been affected by usual 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 components to examine that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician 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 6, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Please remember to examine by passing 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 dried out and cause noise, in which case take them out from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced 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 6. To swap them go to your mechanic.
Other speed bump noise Mazda 6
If, even though all its assumptions, you still can’t find the source of the noise your Mazda 6 makes when you pass a speed bump, we suggest you to consult this article on a loud noise on Mazda 6 or to visit your technician in order to carry an in-depth check on your Mazda 6 and identify this issue.
