Experiencing noises from your vehicle frequently is never comforting, so hearing noises on your Citroen C4 Cactus suspensions when you pass a speed bump can be worrying. This symptom may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the source and take the necessary actions to resolve the problem, it is with this objective 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, after that, what can be the cause 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 C4 Cactus
Check Citroen C4 Cactus suspension
If you experience a suspension noise when you pass a speed bump on your Citroen C4 Cactus, and it is categorized 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 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 vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Citroen C4 Cactus 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Citroen C4 Cactus, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Citroen C4 Cactus 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 adjust direction. If this is the case, 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 causes of your noises, to verify it, position it under the car and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Citroen C4 Cactus to your auto technician or change 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 C4 Cactus, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Remember to verify by passing under your car 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 cause 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, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Citroen C4 Cactus. To replace them go to your auto technician.
