Discovering noises from your car often is never reassuring, so hearing noises on your Renault Scenic 2 suspensions when you pass a speed bump can be stressful. This warning sign may be a sign of a minor issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the cause and take the necessary actions to solve the issue, it is with this intention in mind that we wanted to write this document 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 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 2
Check Renault Scenic 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Scenic 2, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. In fact, 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 examine if this is the issue that concerns you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Renault Scenic 2 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 functions is deteriorated and it is possible to experience a sound 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 circumstances 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 2, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Scenic 2 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 change direction. If this is the situation, 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 examine it, position it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your Renault Scenic 2 to your technician or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Renault Scenic 2, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Bear in mind to examine by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them off from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Renault Scenic 2. To swap them go to your auto technician.
Other speed bump noise Renault Scenic 2
If, even though all its assumptions, you still can’t find the source of the noise your Renault Scenic 2 makes when you pass a speed bump, we advise you to read this article on a loud noise on Renault Scenic 2 or to visit your technician in order to carry an in-depth check on your Renault Scenic 2 and determine this issue.
