Listening noises from your auto often is never comforting, so listening noises on your Nissan Navara suspensions when you pass a speed bump can be stressing. This indicator may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to correct the problem, it is with this aim in mind that we wanted to write this article 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 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 Navara
Check Nissan Navara suspension
If you notice a suspension noise when you pass a speed bump on your Nissan Navara, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the problem that concerns 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 changing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Nissan Navara 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion. To verify 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 conditions you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Nissan Navara passes over a speed bumps, it is imaginable 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 components 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 verify it, put it under the vehicle and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Keep in mind to take your Nissan Navara to your auto mechanic or swap 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 Navara, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind to verify by passing under your vehicle the condition of the paint on your bar which will show 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 solve the problem.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will make 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 Navara. To replace them go to your auto technician.
Other speed bump noise Nissan Navara
If, even though all its assumptions, you still can’t uncover the origin of the noise your Nissan Navara makes when you pass a speed bump, we advise you to read this article on a loud noise on Nissan Navara or to visit your auto mechanic in order to carry an in-depth check on your Nissan Navara and find this problem.
