Listening noises from your auto regularly is never reassuring, so listening noises on your Citroen C5 suspensions when you pass a speed bump can be stressing. 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 fundamental to check the origin and take the necessary actions to resolve the issue, 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 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 C5
Check Citroen C5 suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen C5, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 check if this is the issue that worries you, take a dented road and listen to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them as soon as possible or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Citroen C5 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Citroen C5, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Citroen C5 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is the case, the components that may have been damaged 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, put it under the automobile and apply twists on each of its components to check that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto 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 Citroen C5, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Keep in mind to check by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point 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 auto, a obvious fatigue of these will make 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 C5. To replace them go to your auto technician.
Other speed bump noise Citroen C5
If, even though all its assumptions, you still can’t uncover the source of the noise your Citroen C5 makes when you pass a speed bump, we recommend you to read this article on a loud noise on Citroen C5 or to visit your auto mechanic in order to carry an in-depth check on your Citroen C5 and determine this issue.
