Listening noises from your auto frequently is never reassuring, so hearing noises on your Renault Grand Modus suspensions when you pass a speed bump can be worrying. This sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. In any case, it is important to check the cause and take the necessary actions to eliminate 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 causes 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 Grand Modus
Check Renault Grand Modus suspension
If you experience a suspension noise when you pass a speed bump on your Renault Grand Modus, and it is categorized 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 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 check 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 circulate over holes. If it is indeed the cups, think of swapping them fairly 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 researched for “Renault Grand Modus 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 amasses inside them their working is degraded and it is possible to experience a sound when they are in torsion. To check 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 replacing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Grand Modus, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Renault Grand Modus passes over a speed bumps, it is possible 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 the situation, the parts that may have been affected 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 check it, place it under the automobile and apply twists on each of its components to check 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 Renault Grand Modus to your technician or swap them if they are involved.
squeaky noise speed bump Renault Grand Modus
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 Grand Modus, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Remember to check by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause 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 check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will create 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 Grand Modus. To replace them go to your auto mechanic.
Other speed bump noise Renault Grand Modus
If, despite all its assumptions, you still can’t uncover the origin of the noise your Renault Grand Modus makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Renault Grand Modus or to visit your technician in order to carry an in-depth check on your Renault Grand Modus and determine this issue.
