Discovering noises from your auto frequently is never reassuring, so listening noises on your Renault Kangoo suspensions when you pass a speed bump can be worrying. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is important to check the cause and take the necessary actions to correct the trouble, it is with this intention in mind that we wanted to write this content 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 Kangoo
Check Renault Kangoo suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Kangoo, and it is categorized by a “clack” or cracking, it is highly plausible 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To check if this is the trouble that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Renault Kangoo 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 old and the dirt/dust builds up inside them their working is degraded 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 Kangoo, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Renault Kangoo 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 change direction. If this is the situation, the parts 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, put 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 supposed to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or change them if they are involved.
squeaky noise speed bump Renault Kangoo
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 Kangoo, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can cause this squeaking noise. Keep in mind to check by going under your car the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case remove them from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the auto, a pronounced fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Renault Kangoo. To replace them go to your auto technician.
Other speed bump noise Renault Kangoo
If, despite all its assumptions, you still can’t find the source of the noise your Renault Kangoo makes when you pass a speed bump, we recommend you to consult this content on a loud noise on Renault Kangoo or to visit your auto technician in order to carry an in-depth check on your Renault Kangoo and identify this trouble.
