Listening noises from your vehicle frequently is never reassuring, so hearing noises on your Honda Civic suspensions when you go over a speed bump can be worrying. This warning sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to solve the issue, it is with this goal in mind that we wanted to write this article to help 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 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 Honda Civic
Check Honda Civic suspension
If you encounter a suspension noise when you pass a speed bump on your Honda Civic, 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 job during small bumps that compress the suspensions. To check 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 replacing them as soon as possible or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Honda Civic 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion. To check 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 replacing it or them. If you have the feeling that this noise is more like a a loud noise on Honda Civic, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Honda Civic 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 modify direction. If this is your situation, the components that may have been damaged by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, position it under the vehicle and apply twists on each of its components to check that there is no particular play on one of them, they are supposed to resist you quite strongly over their entire travel. Please remember to take your vehicle to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Honda Civic, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Remember to check 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 cause noise, in which case take them out from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious fatigue 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 Honda Civic. To swap them go to your mechanic.
Other speed bump noise Honda Civic
If, even though all its assumptions, you still can’t uncover the origin of the noise your Honda Civic makes when you pass a speed bump, we suggest you to read this content on a loud noise on Honda Civic or to visit your auto technician in order to carry an in-depth check on your Honda Civic and find this issue.
