Finding out noises from your vehicle often is never reassuring, so discovering noises on your Renualt Express suspensions when you go over a speed bump can be worrying. This indicator may be a sign of a insignificant problem 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 correct the problem, it is with this aim in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons 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 Renualt Express
Check Renualt Express suspension
If you experience a suspension noise when you pass a speed bump on your Renualt Express, and it is categorized by a “clack” or cracking, it is highly possible 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To check if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them fairly quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Renualt Express 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renualt Express, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renualt Express 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 change direction. If this is the situation, the parts that may have been destroyed by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, place it under the car and apply twists on each of its components to check that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Keep in mind to take your Renualt Express to your auto technician or replace them if they are involved.
squeaky noise speed bump Renualt Express
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 Renualt Express, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Keep in mind to check by going under your car the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case remove them from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a pronounced weakness of these will generate 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 Renualt Express. To swap them go to your mechanic.
Other speed bump noise Renualt Express
If, even though all its assumptions, you still can’t locate the source of the noise your Renualt Express makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Renualt Express or to visit your auto technician in order to carry an in-depth check on your Renualt Express and identify this problem.
