Discovering noises from your car often is never reassuring, so discovering noises on your Mazda 5 suspensions when you pass a speed bump can be stressful. This symptom may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to solve the trouble, it is with this intention 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, 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 5
Check Mazda 5 suspension
If you encounter a suspension noise when you pass a speed bump on your Mazda 5, and it is characterized 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 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 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 drive 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 vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Mazda 5 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Mazda 5, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Mazda 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 modify direction. If this is the situation, the parts that may have been destroyed by regular 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, position it under the vehicle and apply twists on each of its components to examine that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your Mazda 5 to your mechanic or replace them if they are involved.
squeaky noise speed bump Mazda 5
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 5, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind to examine by going under your vehicle 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 dry and create noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a noticable weakness 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 5. To change them go to your mechanic.
Other speed bump noise Mazda 5
If, even though all its assumptions, you still can’t locate the source of the noise your Mazda 5 makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Mazda 5 or to visit your mechanic in order to carry an in-depth check on your Mazda 5 and identify this trouble.
