Finding out noises from your car frequently is never comforting, so listening noises on your Renault Grand Espace suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is important to check the cause 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 causes 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 Grand Espace
Check Renault Grand Espace suspension
If you notice a suspension noise when you pass a speed bump on your Renault Grand Espace, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 check if this is the issue that concerns you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping 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 searched for “Renault Grand Espace 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 old and the dirt/dust builds up inside them their action 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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Renault Grand Espace 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 adjust direction. If this is your situation, 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 check it, position it under the car and apply twists on each of its elements to check that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Remember 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 pass a speed bump with your Renault Grand Espace, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can cause this squeaking noise. Keep in mind to check by going under your car the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them out from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a noticable fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Renault Grand Espace. To replace them go to your auto technician.
