Check Citroen C4 Picasso 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen C4 Picasso 2, 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 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 check if this is the problem that worries you, take a dented road and listen to the noise coming from your front axle as you drive 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 maintenance.
Check the cardan shaft
If you are here because you have looked for for “Citroen C4 Picasso 2 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 builds up inside them their action is degraded 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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Citroen C4 Picasso 2, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Citroen C4 Picasso 2 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 modify direction. If this is the case, the components that may have been damaged by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes 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 meant to resist you quite strongly over their entire travel. Please remember to take your Citroen C4 Picasso 2 to your technician or replace 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 C4 Picasso 2, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Bear in mind to check by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case 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 noticable weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Citroen C4 Picasso 2. To change them go to your auto technician.
