Hearing noises from your vehicle regularly is never reassuring, so hearing noises on your Nissan Pulsar suspensions when you go over a speed bump can be stressful. This warning sign 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 fundamental to check the source and take the necessary actions to correct the problem, it is with this objective in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons 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 Pulsar
Check Nissan Pulsar suspension
If you encounter a suspension noise when you pass a speed bump on your Nissan Pulsar, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 check 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 changing them as soon as possible or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have looked for for “Nissan Pulsar 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Pulsar, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Nissan Pulsar passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been affected 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 check it, put it under the car and apply twists on each of its components to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your Nissan Pulsar to your auto technician or swap them if they are involved.
squeaky noise speed bump Nissan Pulsar
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 Pulsar, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can provoke this squeaking noise. Please remember to check by going under your car the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Nissan Pulsar. To swap them go to your auto mechanic.
Other speed bump noise Nissan Pulsar
If, even though all its assumptions, you still can’t find the source of the noise your Nissan Pulsar makes when you pass a speed bump, we encourage you to refer to this content on a loud noise on Nissan Pulsar or to visit your auto technician in order to carry an in-depth check on your Nissan Pulsar and find this problem.
