Finding out noises from your automobile regularly is never reassuring, so hearing noises on your Renault Scenic suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the origin and take the necessary actions to solve the trouble, it is with this objective in mind that we wanted to write this content to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, after that, what can be the cause 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 Renault Scenic
Check Renault Scenic suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Scenic, 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the trouble that worries you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of swapping them quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Renault Scenic 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 conditions 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, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Scenic passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary direction. If this is the case, 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 examine it, place it under the vehicle and apply twists on each of its components to examine that there is no particular play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your Renault Scenic to your mechanic 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 go over a speed bump with your Renault Scenic, 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 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 provoke noise, in which case disassemble them from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced fatigue 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. To change them go to your mechanic.
