Hearing noises from your automobile frequently is never comforting, so discovering noises on your Renault Espace suspensions when you go over a speed bump can be disturbing. This sign may be a sign of a insignificant trouble as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to solve 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 explanations 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 Espace
Check Renault Espace suspension
If you notice a suspension noise when you pass a speed bump on your Renault Espace, 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 old, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To verify if this is the trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you drive 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 repairs.
Check the cardan shaft
If you are here because you have searched for “Renault Espace 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 builds up inside them their functions is degraded and it is possible to experience a noise 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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Espace, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Espace passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is the case, the parts that may have been damaged 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, place 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. Keep in mind to take your Renault Espace to your technician or swap them if they are involved.
squeaky noise speed bump Renault Espace
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 Espace, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Remember to verify by going under your vehicle 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 dry and cause noise, in which case remove them from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a noticable fatigue of these will generate 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 Espace. To change them go to your auto mechanic.
Other speed bump noise Renault Espace
If, even though all its assumptions, you still can’t uncover the origin of the noise your Renault Espace makes when you pass a speed bump, we encourage you to refer to this article on a loud noise on Renault Espace or to visit your technician in order to carry an in-depth check on your Renault Espace and discover this trouble.
