Listening noises from your car frequently is never comforting, so discovering noises on your Renault Vel Satis suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a small 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 resolve the issue, it is with this aim in mind that we wanted to write this content to help 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 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 Vel Satis
Check Renault Vel Satis suspension
If you notice a suspension noise when you pass a speed bump on your Renault Vel Satis, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 issue that concerns you, take a dented road and focus on the noise coming from your front axle as you go 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 looked for for “Renault Vel Satis 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Vel Satis, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Vel Satis 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 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 causes of your noises, to verify it, place 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 expected to resist you quite strongly over their entire travel. Please remember to take your Renault Vel Satis to your technician or change them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Renault Vel Satis, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Remember to verify by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should resolve the issue.
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 car, a evident weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Renault Vel Satis. To replace them go to your mechanic.

If, even though all its assumptions, you still can’t locate the source of the noise your Renault Vel Satis makes when you pass a speed bump, we suggest you to consult this article on a loud noise on Renault Vel Satis or to visit your technician in order to carry an in-depth check on your Renault Vel Satis and discover this issue.
