Discovering noises from your car often is never comforting, so hearing noises on your Nissan Cube suspensions when you go over a speed bump can be disturbing. This symptom may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to resolve the problem, it is with this objective in mind that we wanted to write this content to help you see more clearly. We will first see the possible reasons 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 Cube
Check Nissan Cube suspension
If you experience a suspension noise when you pass a speed bump on your Nissan Cube, and it is characterized by a “clack” or cracking, it is highly plausible 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To check if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have searched for “Nissan Cube 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Cube, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Nissan Cube 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 modify direction. If this is the case, the components that may have been destroyed by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, place it under the vehicle and apply twists on each of its components to check that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician or change them if they are involved.
squeaky noise speed bump Nissan Cube
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 Cube, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Please remember to check by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a pronounced weakness of these will create 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 Nissan Cube. To replace them go to your auto technician.
Other speed bump noise Nissan Cube
If, despite all its assumptions, you still can’t uncover the source of the noise your Nissan Cube makes when you pass a speed bump, we advise you to read this article on a loud noise on Nissan Cube or to visit your technician in order to carry an in-depth check on your Nissan Cube and identify this problem.
