Suspension cracking noise Mazda MX 5 Miata

Check Mazda MX 5 Miata suspension

If you encounter a suspension noise when you pass a speed bump on your Mazda MX 5 Miata, and it is categorized 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 old, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the trouble that worries you, take a dented road and focus on the noise coming from your front axle as you circulate 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 MX 5 Miata 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 accumulates inside them their action 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 make a turn at low speed. If it cracks in these two situations you should consider swapping it or them.

Check steering hinges/stabilizer bar

Finally, when you detect a suspension noise when your Mazda MX 5 Miata passes over a speed bumps, it is possible 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 components that may have been destroyed 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, place it under the automobile and apply twists on each of its elements to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel.

Check the stabilizer bar

If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Mazda MX 5 Miata, 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 passing under your automobile the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case remove them from the cradle and grease them, this should resolve the trouble.

Check engine silentblocks

Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a noticable weakness of these will generate 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 MX 5 Miata.
