Suspension cracking noise Renault Scenic 4
Check Renault Scenic 4 suspension
If you experience a suspension noise when you pass a speed bump on your Renault Scenic 4, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the issue that worries 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 damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Renault Scenic 4 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 accumulates inside them their action is degraded and it is possible to experience a noise 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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Scenic 4, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Scenic 4 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you modify direction. If this is the case, the parts that may have been destroyed 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 elements to verify that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your vehicle to your 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 Renault Scenic 4, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Remember to verify by passing under your vehicle 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 bring on noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, 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 happens when you pass a speed bumps or any holes with your Renault Scenic 4. To swap them go to your auto technician.
