Discovering noises from your vehicle often is never comforting, so discovering noises on your Nissan NV200 suspensions when you pass a speed bump can be stressing. This sign may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the source and take the necessary actions to correct the trouble, it is with this aim 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, 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 Nissan NV200
Check Nissan NV200 suspension
If you encounter a suspension noise when you pass a speed bump on your Nissan NV200, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the trouble that concerns you, take a dented road and listen to 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 affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Nissan NV200 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 NV200, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Nissan NV200 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 vary direction. If this is the case, the parts that may have been affected by usual 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 vehicle and apply twists on each of its components to examine 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 Nissan NV200 to your auto technician or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Nissan NV200, 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 generate this squeaking noise. Keep in mind to examine by going under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out 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 process as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious 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 NV200. To swap them go to your technician.
Other speed bump noise Nissan NV200
If, despite all its assumptions, you still can’t locate the source of the noise your Nissan NV200 makes when you pass a speed bump, we advise you to read this article on a loud noise on Nissan NV200 or to visit your auto technician in order to carry an in-depth check on your Nissan NV200 and identify this trouble.
