Finding out noises from your automobile often is never comforting, so hearing noises on your Citroen C3 suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to correct the problem, it is with this intention in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations 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 C3
Check Citroen C3 suspension
If you experience a suspension noise when you pass a speed bump on your Citroen C3, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 examine if this is the problem that concerns you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Citroen C3 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is deteriorated and it is possible to experience a noise when they are in torsion. To examine 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 Citroen C3, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Citroen C3 passes over a speed bumps, it is imaginable 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 your situation, the components that may have been affected 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 examine it, put it under the vehicle and apply twists on each of its elements to examine that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Citroen C3, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Bear in mind to examine by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second plausible point, 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 problem.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a noticable fatigue of these will generate 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 C3. To swap them go to your technician.
Other speed bump noise Citroen C3
If, despite all its assumptions, you still can’t locate the origin of the noise your Citroen C3 makes when you pass a speed bump, we suggest you to read this article on a loud noise on Citroen C3 or to visit your mechanic in order to carry an in-depth check on your Citroen C3 and identify this problem.
