Listening noises from your automobile frequently is never reassuring, so hearing noises on your Renault Megane suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a minor problem as well as a warning of a much larger repair to come. In any case, it is fundamental to check the cause and take the necessary actions to solve the problem, it is with this intention in mind that we wanted to write this content 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 reason 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
Check Renault Megane suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Megane, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the problem that concerns 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 changing them quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Renault Megane 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Megane, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Renault Megane 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 vary direction. If this is the situation, the parts that may have been affected by normal 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, position it under the vehicle and apply twists on each of its components to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto mechanic or replace 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 go over a speed bump with your Renault Megane, 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 create this squeaking noise. Please remember to verify by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second possible point, 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 fix the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Renault Megane. To replace them go to your auto technician.
Other speed bump noise Renault Megane
If, despite all its assumptions, you still can’t locate the origin of the noise your Renault Megane makes when you pass a speed bump, we advise you to read this content on a loud noise on Renault Megane or to visit your auto mechanic in order to carry an in-depth check on your Renault Megane and determine this problem.
