Whatever the case, it is fundamental to check the origin and take the necessary actions to resolve 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 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 Megane 3
Check Renault Megane 3 suspension
If you experience a suspension noise when you pass a speed bump on your Renault Megane 3, 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 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 verify if this is the issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you go 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 auto repairs.
Check the cardan shaft
If you are here because you have searched for “Renault Megane 3 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 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 Megane 3, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Megane 3 passes over a speed bumps, it is imaginable 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 your situation, the parts that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, place it under the automobile and apply twists on each of its components to verify that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your Renault Megane 3 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 pass a speed bump with your Renault Megane 3, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Remember to verify by going under your automobile the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case disassemble them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Renault Megane 3. To swap them go to your auto mechanic.
