Suspension cracking noise Nissan Armada
Check Nissan Armada suspension
If you notice a suspension noise when you pass a speed bump on your Nissan Armada, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 verify if this is the trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Nissan Armada 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 old 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 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 make a turn at low speed. If it cracks in these two circumstances you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Armada, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Nissan Armada passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify direction. If this is the situation, the components that may have been destroyed 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 verify it, position it under the car and apply twists on each of its components to verify 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 vehicle to your mechanic or change them if they are involved.
squeaky noise speed bump Nissan Armada
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Nissan Armada, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Keep in mind to verify by going under your car the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them out from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, 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 occurs when you pass a speed bumps or any holes with your Nissan Armada. To swap them go to your auto mechanic.
