Suspension cracking noise Renault Trafic 2
Check Renault Trafic 2 suspension
If you experience a suspension noise when you pass a speed bump on your Renault Trafic 2, 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 old, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the trouble that worries 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 swapping them as soon as possible 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 looked for for “Renault Trafic 2 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 situations you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Trafic 2 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 modify direction. If this is the situation, the parts that may have been broken by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to examine it, place it under the car and apply twists on each of its elements to examine 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 vehicle to your auto technician or swap 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 Trafic 2, 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 examine by passing under your car the condition of the paint on your bar which will indicate 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 remove them from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a obvious 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 Trafic 2. To change them go to your mechanic.
Other speed bump noise Renault Trafic 2
If, even though all its assumptions, you still can’t uncover the origin of the noise your Renault Trafic 2 makes when you pass a speed bump, we encourage you to consult this article on a loud noise on Renault Trafic 2 or to visit your auto technician in order to carry an in-depth check on your Renault Trafic 2 and find this trouble.
