Listening noises from your vehicle frequently is never comforting, so discovering noises on your Citroen Jumpy suspensions when you go over a speed bump can be disturbing. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the source and take the necessary actions to resolve the issue, it is with this aim in mind that we wanted to write this content to help you see more clearly. We will first see the possible causes for a crack when the speed bump passes, then, what can be the reason of a squeaking noise when a speed bump is being passed and finally what to do if you have another noise when a speed bump is passed.
Suspension cracking noise Citroen Jumpy
Check Citroen Jumpy suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen Jumpy, 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 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 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 replacing them fairly quickly or you may ruin other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Citroen Jumpy 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 old and the dirt/dust amasses inside them their operation is deteriorated 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 turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Citroen Jumpy, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Citroen Jumpy passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the situation, the components that may have been affected 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 verify it, place it under the vehicle and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your Citroen Jumpy to your auto technician or change them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Citroen Jumpy, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Bear in mind to verify by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious fatigue 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 Jumpy. To replace them go to your mechanic.
Other speed bump noise Citroen Jumpy
If, even though all its assumptions, you still can’t find the source of the noise your Citroen Jumpy makes when you pass a speed bump, we suggest you to read this article on a loud noise on Citroen Jumpy or to visit your auto technician in order to carry an in-depth check on your Citroen Jumpy and discover this issue.
