Listening noises from your automobile frequently is never comforting, so listening noises on your Renault Espace 4 suspensions when you go over a speed bump can be worrying. This symptom may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the origin and take the necessary actions to correct the issue, 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 Espace 4
Check Renault Espace 4 suspension
If you experience a suspension noise when you pass a speed bump on your Renault Espace 4, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 role during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of replacing them 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 4 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a noise when they are in torsion. To examine 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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renault Espace 4, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Espace 4 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 change direction. If this is your situation, the components 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 causes of your noises, to examine it, place it under the vehicle and apply twists on each of its components to examine that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician or replace them if they are involved.

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 4, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Please remember to examine 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 dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced 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 Espace 4. To change them go to your mechanic.
Other speed bump noise Renault Espace 4
If, despite all its assumptions, you still can’t find the source of the noise your Renault Espace 4 makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Renault Espace 4 or to visit your technician in order to carry an in-depth check on your Renault Espace 4 and find this issue.
