Discovering noises from your car frequently is never comforting, so hearing noises on your Mazda 2 suspensions when you pass a speed bump can be worrying. This symptom 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 eliminate the trouble, it is with this aim 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, 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 2
Check Mazda 2 suspension
If you experience a suspension noise when you pass a speed bump on your Mazda 2, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the trouble that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them fairly quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Mazda 2 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a noise when they are in torsion. To check 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Mazda 2, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Mazda 2 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify 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 check it, put it under the car and apply twists on each of its components to check that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind to take your Mazda 2 to your technician or change 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 2, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Bear in mind to check by going under your car the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them out from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Mazda 2. To replace them go to your technician.
