Finding out noises from your automobile frequently is never comforting, so hearing noises on your Renault Megane 2 suspensions when you go over a speed bump can be stressful. This indicator may be a sign of a small trouble as well as a warning of a much larger repair to come. In any case, it is essential to check the cause and take the necessary actions to correct the trouble, it is with this goal in mind that we wanted to write this content 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 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 2
Check Renault Megane 2 suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Megane 2, and it is characterized by a “clack” or cracking, it is highly plausible 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 trouble that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them as soon as possible or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Renault Megane 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 situations 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 2, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Renault Megane 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 vary direction. If this is your situation, the parts that may have been destroyed 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, put it under the vehicle and apply twists on each of its elements to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your Renault Megane 2 to your technician or change them if they are involved.
squeaky noise speed bump Renault Megane 2
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 2, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Keep in mind to verify by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case remove them from the cradle and grease them, this should eliminate the trouble.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will generate 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 Megane 2. To swap them go to your mechanic.
Other speed bump noise Renault Megane 2
If, despite all its assumptions, you still can’t uncover the source of the noise your Renault Megane 2 makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Renault Megane 2 or to visit your technician in order to carry an in-depth check on your Renault Megane 2 and discover this trouble.
