Discovering noises from your vehicle regularly is never comforting, so listening noises on your Citroen C1 suspensions when you pass a speed bump can be worrying. This indicator may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is essential to check the origin and take the necessary actions to solve the issue, it is with this aim in mind that we wanted to write this document to support you see more clearly. We will first see the possible causes for a crack when the speed bump passes, then, 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 C1
Check Citroen C1 suspension
If you experience a suspension noise when you pass a speed bump on your Citroen C1, 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 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 function during small bumps that compress the suspensions. To verify if this is the issue that worries 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 changing 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 C1 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 old and the dirt/dust accumulates inside them their action is deteriorated 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 C1, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Citroen C1 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary direction. If this is the case, the parts that may have been broken 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 verify it, place it under the vehicle and apply twists on each of its components to verify 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 Citroen C1 to your technician or replace them if they are involved.
squeaky noise speed bump Citroen C1
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 C1, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Keep in mind to verify by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should solve the issue.
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 evident weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Citroen C1. To swap them go to your auto mechanic.
Other speed bump noise Citroen C1
If, despite all its assumptions, you still can’t uncover the origin of the noise your Citroen C1 makes when you pass a speed bump, we encourage you to read this content on a loud noise on Citroen C1 or to visit your technician in order to carry an in-depth check on your Citroen C1 and identify this issue.
