Check Citroen Grand C4 Picasso suspension
If you notice a suspension noise when you pass a speed bump on your Citroen Grand C4 Picasso, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are old, 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 trouble that concerns 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 swapping them as soon as possible or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Citroen Grand C4 Picasso 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 situations you should consider swapping it or them.

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

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 Grand C4 Picasso, it is plausible that it is the stabilizer bar itself that is concerned.

Keep in mind to examine by going under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a evident weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Citroen Grand C4 Picasso.
