Suspension cracking noise Citroen Jumper 2
Check Citroen Jumper 2 suspension
If you experience a suspension noise when you pass a speed bump on your Citroen Jumper 2, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, 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 concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing 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 Jumper 2 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Citroen Jumper 2 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible.

If this is the situation, the components that may have been affected 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 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 supposed to endure you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Citroen Jumper 2, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Keep in mind to verify by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case disassemble them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last point 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 car, 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 occurs when you pass a speed bumps or any holes with your Citroen Jumper 2. To replace them go to your mechanic.
