Hearing noises from your vehicle often is never comforting, so hearing noises on your Nissan Micra 2 suspensions when you go over a speed bump can be disturbing. This sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the source and take the necessary actions to correct the trouble, it is with this objective in mind that we wanted to write this document to help you see more clearly. We will first see the possible causes for a crack when the speed bump passes, after that, 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 2
Check Nissan Micra 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Nissan Micra 2, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 job during small bumps that compress the suspensions. To examine if this is the trouble that worries you, take a dented road and focus on the noise coming from your front axle as you go 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 repairs.
Check the cardan shaft
If you are here because you have searched for “Nissan Micra 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 old and the dirt/dust amasses inside them their functions 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 turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Micra 2, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Nissan Micra 2 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the components that may have been broken by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to examine it, place it under the car and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Nissan Micra 2 to your auto technician or change them if they are involved.

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 2, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Keep in mind to examine by going under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them off from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue of these will create 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 Nissan Micra 2. To swap them go to your technician.
Other speed bump noise Nissan Micra 2
If, even though all its assumptions, you still can’t uncover the origin of the noise your Nissan Micra 2 makes when you pass a speed bump, we suggest you to read this article on a loud noise on Nissan Micra 2 or to visit your auto technician in order to carry an in-depth check on your Nissan Micra 2 and identify this trouble.
