Listening noises from your automobile regularly is never reassuring, so listening noises on your Renault Kadjar suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. In any case, it is essential to check the source and take the necessary actions to resolve the problem, it is with this aim in mind that we wanted to write this document to support you see more clearly. We will first see the possible explanations 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 Kadjar
Check Renault Kadjar suspension
If you experience a suspension noise when you pass a speed bump on your Renault Kadjar, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 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 damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have researched for “Renault Kadjar 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Renault Kadjar, don’t hesitate to check out this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Renault Kadjar passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the parts that may have been affected by usual 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, put it under the car and apply twists on each of its components to check that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your Renault Kadjar to your technician or replace them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Renault Kadjar, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can provoke 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 point, it may be your stabilizer bar silentblocks that are dry and cause 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, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a evident weakness of these will create 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 Kadjar. To replace them go to your mechanic.
Other speed bump noise Renault Kadjar
If, despite all its assumptions, you still can’t uncover the source of the noise your Renault Kadjar makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Renault Kadjar or to visit your technician in order to carry an in-depth check on your Renault Kadjar and identify this problem.
