Listening noises from your car frequently is never reassuring, so hearing noises on your Renault Captur suspensions when you pass a speed bump can be stressing. This warning sign may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to correct the trouble, it is with this objective 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, after that, 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 Captur
Check Renault Captur suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Captur, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, 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 role during small bumps that compress the suspensions. To examine if this is the trouble 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 swapping them fairly quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Renault Captur 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renault Captur, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Renault Captur passes over a speed bumps, it is imaginable 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 the case, the parts that may have been damaged 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 examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Renault Captur to your mechanic or change them if they are involved.
squeaky noise speed bump Renault Captur
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 Captur, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Keep in mind to examine by passing under your vehicle 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 dry and bring on noise, in which case disassemble them from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Renault Captur. To replace them go to your auto technician.
Other speed bump noise Renault Captur
If, even though all its assumptions, you still can’t uncover the origin of the noise your Renault Captur makes when you pass a speed bump, we advise you to read this article on a loud noise on Renault Captur or to visit your mechanic in order to carry an in-depth check on your Renault Captur and determine this trouble.
