Listening noises from your vehicle frequently is never comforting, so hearing noises on your Acura MDX suspensions when you pass a speed bump can be disturbing. 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 essential to check the cause and take the necessary actions to correct the issue, it is with this goal in mind that we wanted to write this document to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, after that, 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 MDX
Check Acura MDX suspension
If you notice a suspension noise when you pass a speed bump on your Acura MDX, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 examine if this is the issue that concerns 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 changing them fairly quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Acura MDX 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Acura MDX, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Acura MDX 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 components that may have been destroyed 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 examine it, put 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 meant to resist you quite strongly over their entire travel. Remember to take your Acura MDX to your mechanic or replace 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 Acura MDX, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Bear in mind to examine 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 dried out and bring on noise, in which case disassemble them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a evident weakness of these will generate 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 Acura MDX. To change them go to your mechanic.
Other speed bump noise Acura MDX
If, even though all its assumptions, you still can’t find the origin of the noise your Acura MDX makes when you pass a speed bump, we recommend you to read this article on a loud noise on Acura MDX or to visit your mechanic in order to carry an in-depth check on your Acura MDX and discover this issue.
