Finding out noises from your auto frequently is never reassuring, so discovering noises on your Nissan Terrano suspensions when you pass a speed bump can be stressful. This sign may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the cause and take the necessary actions to eliminate 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 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 Terrano
Check Nissan Terrano suspension
If you experience a suspension noise when you pass a speed bump on your Nissan Terrano, and it is characterized by a “clack” or cracking, it is highly plausible 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 function during small bumps that compress the suspensions. To check if this is the issue that concerns you, take a dented road and focus on the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Nissan Terrano 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Nissan Terrano, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Nissan Terrano 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 the situation, the components that may have been damaged by normal 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 supposed to endure you quite strongly over their entire travel. Please remember to take your Nissan Terrano to your mechanic or replace 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 Terrano, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Please remember to check by passing under your automobile 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 dry and bring on noise, in which case take them out from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Nissan Terrano. To change them go to your auto mechanic.
Other speed bump noise Nissan Terrano
If, even though all its assumptions, you still can’t find the origin of the noise your Nissan Terrano makes when you pass a speed bump, we recommend you to read this article on a loud noise on Nissan Terrano or to visit your mechanic in order to carry an in-depth check on your Nissan Terrano and discover this issue.
