Listening noises from your car frequently is never reassuring, so listening noises on your Acura RDX suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a minor problem 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 problem, it is with this objective in mind that we wanted to write this content to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, what can be the cause 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 Acura RDX
Check Acura RDX suspension
If you encounter a suspension noise when you pass a speed bump on your Acura RDX, and it is categorized by a “clack” or cracking, it is highly plausible 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 job during small bumps that compress the suspensions. To verify if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them fairly quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Acura RDX 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 builds up inside them their working is degraded 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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Acura RDX, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Acura RDX 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 adjust direction. If this is the situation, the components that may have been broken 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, put it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are meant to endure you quite strongly over their entire travel. Please remember to take your Acura RDX to your mechanic or swap them if they are involved.
squeaky noise speed bump Acura RDX
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Acura RDX, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case take them out from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will make 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 Acura RDX. To replace them go to your auto technician.
Other speed bump noise Acura RDX
If, despite all its assumptions, you still can’t uncover the source of the noise your Acura RDX makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Acura RDX or to visit your mechanic in order to carry an in-depth check on your Acura RDX and find this problem.
