Suspension cracking noise Infiniti Q50
Check Infiniti Q50 suspension
If you experience a suspension noise when you pass a speed bump on your Infiniti Q50, 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 old, 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 pass over holes. If it is indeed the cups, think of changing them as soon as possible or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Infiniti Q50 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 old 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 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 turn at low speed. If it cracks in these two situations you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Infiniti Q50 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 your situation, the components 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 examine it, place it under the vehicle and apply twists on each of its elements to examine that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Infiniti Q50, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to examine by passing under your vehicle the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case take them off from the cradle and grease them, this should eliminate 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 automobile, a evident weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Infiniti Q50. To replace them go to your technician.
