Suspension cracking noise Citroen Ds4

Check Citroen Ds4 suspension

If you encounter a suspension noise when you pass a speed bump on your Citroen Ds4, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the problem that concerns 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 swapping them fairly quickly or you may ruin other parts and have to make more important vehicle repairs.

Check the cardan shaft

If you are here because you have looked for for “Citroen Ds4 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is degraded and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two situations you should consider swapping it or them.

Check steering hinges/stabilizer bar

Finally, when you experience a suspension noise when your Citroen Ds4 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the parts that may have been broken by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, place 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 expected to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto 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 go over a speed bump with your Citroen Ds4, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Remember to examine by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them off from the cradle and grease them, this should solve the problem.

Check engine silentblocks

Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, 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 comes up when you pass a speed bumps or any holes with your Citroen Ds4. To replace them go to your technician.
