Experiencing noises from your auto regularly is never comforting, so discovering noises on your Renault Trafic 3 suspensions when you go over a speed bump can be worrying. This sign may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the source and take the necessary actions to resolve the problem, it is with this goal in mind that we wanted to write this document to help you see more clearly. We will first see the possible explanations 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 Trafic 3
Check Renault Trafic 3 suspension
If you notice a suspension noise when you pass a speed bump on your Renault Trafic 3, and it is categorized 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them as soon as possible or you may damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Renault Trafic 3 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 accumulates inside them their operation is deteriorated and it is possible to experience a noise 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 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 Trafic 3, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Renault Trafic 3 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is the case, the components that may have been affected by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to check it, position it under the car and apply twists on each of its components to check that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Renault Trafic 3 to your mechanic 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 Trafic 3, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Bear in mind to check by passing 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 dried out and provoke noise, in which case take them out from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Renault Trafic 3. To replace them go to your mechanic.
Other speed bump noise Renault Trafic 3
If, despite all its assumptions, you still can’t uncover the origin of the noise your Renault Trafic 3 makes when you pass a speed bump, we suggest you to read this content on a loud noise on Renault Trafic 3 or to visit your mechanic in order to carry an in-depth check on your Renault Trafic 3 and discover this problem.
