Suspension cracking noise Renault Kangoo 2
Check Renault Kangoo 2 suspension
If you experience a suspension noise when you pass a speed bump on your Renault Kangoo 2, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 verify if this is the issue that concerns 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 replacing them quickly 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 Kangoo 2 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion. To verify 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 circumstances you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Renault Kangoo 2, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Kangoo 2 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the parts that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, put it under the vehicle and apply twists on each of its elements to verify that there is no particular play on one of them, they are meant to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto mechanic 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 Kangoo 2, 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. Bear in mind to verify by going under your vehicle 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 cause noise, in which case disassemble them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Renault Kangoo 2. To replace them go to your auto technician.
