Listening noises from your vehicle regularly is never reassuring, so listening noises on your Citroen C8 suspensions when you go over 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. In any case, it is essential to check the cause and take the necessary actions to solve 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, then, 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 C8
Check Citroen C8 suspension
If you notice a suspension noise when you pass a speed bump on your Citroen C8, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 problem that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them fairly quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Citroen C8 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 old and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a sound 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Citroen C8, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Citroen C8 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 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 check it, place it under the vehicle and apply twists on each of its components to check 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 C8 to your auto 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 go over a speed bump with your Citroen C8, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Please remember to check by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them out from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Citroen C8. To swap them go to your auto technician.
Other speed bump noise Citroen C8
If, despite all its assumptions, you still can’t uncover the source of the noise your Citroen C8 makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Citroen C8 or to visit your auto technician in order to carry an in-depth check on your Citroen C8 and determine this problem.
