Experiencing noises from your auto often is never reassuring, so hearing noises on your Renault Twizy suspensions when you pass a speed bump can be disturbing. This warning sign may be a sign of a minor issue as well as a warning of a much larger repair to come. Whatever the case, it is fundamental 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 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 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 Twizy
Check Renault Twizy suspension
If you notice a suspension noise when you pass a speed bump on your Renault Twizy, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 examine if this is the issue that concerns 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 swapping them quickly or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Renault Twizy 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Twizy, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Renault Twizy passes over a speed bumps, it is plausible 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 parts that may have been affected by regular 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, put it under the car and apply twists on each of its components to examine that there is no special play on one of them, they are meant to resist 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, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Renault Twizy, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to examine by going under your car 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 bring on noise, in which case take them off from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Renault Twizy. To swap them go to your technician.
Other speed bump noise Renault Twizy
If, even though all its assumptions, you still can’t find the origin of the noise your Renault Twizy makes when you pass a speed bump, we advise you to consult this article on a loud noise on Renault Twizy or to visit your technician in order to carry an in-depth check on your Renault Twizy and identify this issue.
