Suspension cracking noise Acura ILX
Check Acura ILX suspension
If you encounter a suspension noise when you pass a speed bump on your Acura ILX, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 issue that concerns you, take a dented road and focus on the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of changing them quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Acura ILX 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 old and the dirt/dust accumulates inside them their operation 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 make a turn at low speed. If it cracks in these two situations you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Acura ILX, don’t hesitate to visit this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Acura ILX passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is the case, the parts 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 causes of your noises, to examine it, position 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 expected to resist you quite strongly over their entire travel. Keep in mind to take your vehicle to your technician 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 ILX, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Please remember to examine by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and provoke noise, in which case disassemble them from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, in fact, these silentblocks function as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will generate 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 ILX. To swap them go to your technician.
