Finding out noises from your car frequently is never reassuring, so listening noises on your Acura TL suspensions when you pass a speed bump can be disturbing.

In any case, it is essential to check the cause and take the necessary actions to eliminate the problem, it is with this goal in mind that we wanted to write this content to help 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 Acura TL
Check Acura TL suspension
If you encounter a suspension noise when you pass a speed bump on your Acura TL, 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 role during small bumps that compress the suspensions. To examine 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 drive over holes. If it is indeed the cups, think of replacing them quickly or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Acura TL 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 functions 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 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 TL, don’t hesitate to refer to this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Acura TL 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 vary direction. If this is the case, the components that may have been affected by regular 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, position it under the car and apply twists on each of its components to examine that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your Acura TL to your auto 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 pass a speed bump with your Acura TL, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Keep in mind to examine by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and bring on noise, in which case remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case 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 car, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Acura TL. To change them go to your mechanic.
