Hearing noises from your automobile often is never comforting, so discovering noises on your Renault Megane 4 suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is important to check the origin and take the necessary actions to correct the issue, it is with this objective in mind that we wanted to write this article to support you see more clearly. We will first see the possible reasons 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 Megane 4
Check Renault Megane 4 suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Megane 4, and it is characterized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the issue that concerns you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of changing 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 searched for “Renault Megane 4 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 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 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 make a 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 Megane 4, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Megane 4 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify 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 verify it, put it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Renault Megane 4 to your auto technician or change 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 Megane 4, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case disassemble them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Renault Megane 4. To swap them go to your technician.
Other speed bump noise Renault Megane 4
If, even though all its assumptions, you still can’t find the source of the noise your Renault Megane 4 makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Renault Megane 4 or to visit your auto technician in order to carry an in-depth check on your Renault Megane 4 and discover this issue.
