Check Citroen C4 Aircross suspension
If you experience a suspension noise when you pass a speed bump on your Citroen C4 Aircross, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To check 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 go over holes. If it is indeed the cups, think of changing them as soon as possible or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Citroen C4 Aircross 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a noise when they are in torsion.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 changing it or them.

The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, put it under the vehicle and apply twists on each of its components to check that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel.

If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Citroen C4 Aircross, it is possible that it is the stabilizer bar itself that is concerned.

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 possible 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 solve the issue.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Citroen C4 Aircross.
