Finding out noises from your automobile regularly is never reassuring, so listening noises on your Nissan Cabstar suspensions when you pass a speed bump can be stressing. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. In any case, it is fundamental to check the cause and take the necessary actions to resolve the trouble, it is with this goal in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, 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-noise-nissan-cabstar

Suspension cracking noise Nissan Cabstar

Check Nissan Cabstar suspension

If you experience a suspension noise when you pass a speed bump on your Nissan Cabstar, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 check if this is the trouble that concerns 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 changing them 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 searched for “Nissan Cabstar 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 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 Cabstar, don’t hesitate to visit this content.

Check steering hinges/stabilizer bar

Finally, when you recognise a suspension noise when your Nissan Cabstar passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the parts that may have been destroyed 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, place it under the vehicle and apply twists on each of its components to check that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your vehicle to your technician 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 pass a speed bump with your Nissan Cabstar, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Remember to check by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.

Check engine silentblocks

Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a evident fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Nissan Cabstar. To swap them go to your auto mechanic.
