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 cracking noise Citroen Nemo
Check Citroen Nemo suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen Nemo, and it is categorized by a “clack” or cracking, it is highly possible 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them fairly quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have researched for “Citroen Nemo 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Citroen Nemo, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Citroen Nemo passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the parts 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 verify it, put it under the car and apply twists on each of its components to verify that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Keep in mind 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 Citroen Nemo, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Bear in mind to verify by going under your car the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last case 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 vehicle, a obvious fatigue 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 Citroen Nemo. To change them go to your auto mechanic.

If, despite all its assumptions, you still can’t uncover the source of the noise your Citroen Nemo makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Citroen Nemo or to visit your technician in order to carry an in-depth check on your Citroen Nemo and determine this problem.
