Listening noises from your vehicle regularly is never reassuring, so listening noises on your Nissan Micra suspensions when you go over a speed bump can be stressful. This indicator may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the origin and take the necessary actions to correct the problem, it is with this objective in mind that we wanted to write this article to support you see more clearly. We will first see the possible causes 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 Nissan Micra
Check Nissan Micra suspension
If you experience a suspension noise when you pass a speed bump on your Nissan Micra, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them as soon as possible or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Nissan Micra 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Micra, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Nissan Micra 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 vary direction. If this is your situation, the components that may have been broken 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 verify it, put it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your Nissan Micra to your auto technician or change them if they are involved.
squeaky noise speed bump Nissan Micra
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 Nissan Micra, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
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 vehicle, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Nissan Micra. To swap them go to your auto technician.
Other speed bump noise Nissan Micra
If, despite all its assumptions, you still can’t find the source of the noise your Nissan Micra makes when you pass a speed bump, we encourage you to refer to this content on a loud noise on Nissan Micra or to visit your auto technician in order to carry an in-depth check on your Nissan Micra and find this problem.
