Finding out noises from your auto often is never comforting, so discovering noises on your Nissan Sentra suspensions when you go over a speed bump can be stressful. This sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to resolve the issue, it is with this intention in mind that we wanted to write this document to support you see more clearly. We will first see the possible explanations 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 Sentra
Check Nissan Sentra suspension
If you experience a suspension noise when you pass a speed bump on your Nissan Sentra, and it is categorized 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 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 check if this is the issue that concerns 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 swapping them as soon as possible or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Nissan Sentra 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Sentra, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Nissan Sentra 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 your situation, the parts that may have been damaged 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, put it under the automobile 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. Please remember to take your Nissan Sentra to your auto mechanic 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 go over a speed bump with your Nissan Sentra, it is possible 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 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 dry and create noise, in which case take them out from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a evident weakness 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 Sentra. To replace them go to your auto mechanic.
Other speed bump noise Nissan Sentra
If, despite all its assumptions, you still can’t find the origin of the noise your Nissan Sentra makes when you pass a speed bump, we advise you to read this content on a loud noise on Nissan Sentra or to visit your auto mechanic in order to carry an in-depth check on your Nissan Sentra and find this issue.
