Finding out noises from your automobile frequently is never reassuring, so discovering noises on your Renault Trafic suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a minor problem as well as a warning of a much larger repair to come. In any case, it is important to check the origin and take the necessary actions to resolve the problem, it is with this intention in mind that we wanted to write this article 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 Trafic
Check Renault Trafic suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Trafic, 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 dead, 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 problem 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 vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Renault Trafic 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renault Trafic, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Renault Trafic passes over a speed bumps, it is possible 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 components that may have been affected 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 check it, position it under the automobile and apply twists on each of its elements to check that there is no particular play on one of them, they are meant 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.
squeaky noise speed bump Renault Trafic
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, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Remember to check by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case disassemble them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the automobile, a evident weakness of these will generate 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 Trafic. To replace them go to your auto mechanic.
Other speed bump noise Renault Trafic
If, despite all its assumptions, you still can’t find the origin of the noise your Renault Trafic makes when you pass a speed bump, we encourage you to read this content on a loud noise on Renault Trafic or to visit your technician in order to carry an in-depth check on your Renault Trafic and determine this problem.
