Suspension cracking noise Renault Master 3
Check Renault Master 3 suspension
If you encounter a suspension noise when you pass a speed bump on your Renault Master 3, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 circulate over holes. If it is indeed the cups, think of changing them 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 searched for “Renault Master 3 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Renault Master 3 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 change direction. If this is the case, the parts that may have been destroyed by regular wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, put it under the car and apply twists on each of its components to verify that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Please remember to take your Renault Master 3 to your auto technician or change 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 pass a speed bump with your Renault Master 3, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Bear in mind to verify by going under your car the condition of the paint on your bar which will show if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them out from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks operate 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 occurs when you pass a speed bumps or any holes with your Renault Master 3. To swap them go to your auto technician.
