Suspension cracking noise Citroen C3 Aircross
Check Citroen C3 Aircross suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen C3 Aircross, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 examine if this is the issue 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 damage 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 Aircross 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is deteriorated and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Citroen C3 Aircross 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 change direction. If this is the situation, 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 causes of your noises, to examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto mechanic 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 pass a speed bump with your Citroen C3 Aircross, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Please remember to examine 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 dried out and create noise, in which case remove them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Citroen C3 Aircross. To change them go to your mechanic.
