Hearing noises from your auto frequently is never reassuring, so hearing noises on your Citroen C4 Spacetourer suspensions when you pass a speed bump can be stressful. This symptom may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to correct the problem, it is with this goal in mind that we wanted to write this article to help you see more clearly. We will first see the possible explanations 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 C4 Spacetourer
Check Citroen C4 Spacetourer suspension
If you encounter a suspension noise when you pass a speed bump on your Citroen C4 Spacetourer, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 problem that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them fairly quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Citroen C4 Spacetourer 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is degraded and it is possible to experience a noise when they are in torsion.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 cases you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Citroen C4 Spacetourer passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been destroyed 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 examine it, put it under the vehicle and apply twists on each of its components to examine that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your technician or change them if they are involved.

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 C4 Spacetourer, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Remember to examine by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and create noise, in which case remove them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Citroen C4 Spacetourer. To replace them go to your mechanic.

If, despite all its assumptions, you still can’t find the source of the noise your Citroen C4 Spacetourer makes when you pass a speed bump, we encourage you to read this article on a loud noise on Citroen C4 Spacetourer or to visit your technician in order to carry an in-depth check on your Citroen C4 Spacetourer and determine this problem.
