Finding out noises from your car frequently is never reassuring, so discovering noises on your Infiniti Q60 suspensions when you go over a speed bump can be stressing. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to resolve the issue, it is with this intention in mind that we wanted to write this article to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, after that, 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 Infiniti Q60
Check Infiniti Q60 suspension
If you experience a suspension noise when you pass a speed bump on your Infiniti Q60, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 verify if this is the issue 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 replacing them fairly quickly or you may damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Infiniti Q60 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Infiniti Q60, don’t hesitate to consult this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Infiniti Q60 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you vary direction. If this is the case, the components that may have been destroyed by normal 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, place it under the vehicle and apply twists on each of its elements to verify that there is no special play on one of them, they are expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your mechanic 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 go over a speed bump with your Infiniti Q60, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Remember to verify by going under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness 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 Infiniti Q60. To swap them go to your mechanic.
Other speed bump noise Infiniti Q60
If, despite all its assumptions, you still can’t uncover the origin of the noise your Infiniti Q60 makes when you pass a speed bump, we suggest you to refer to this article on a loud noise on Infiniti Q60 or to visit your mechanic in order to carry an in-depth check on your Infiniti Q60 and determine this issue.
