Listening noises from your vehicle often is never reassuring, so hearing noises on your Hyundai Ioniq suspensions when you go over a speed bump can be worrying. This warning sign 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 essential to check the origin and take the necessary actions to solve the problem, it is with this intention 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 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 Hyundai Ioniq
Check Hyundai Ioniq suspension
If you encounter a suspension noise when you pass a speed bump on your Hyundai Ioniq, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 check if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them fairly quickly or you may affect other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Hyundai Ioniq 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 action is degraded 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 turn at low speed. If it cracks in these two situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Hyundai Ioniq, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Hyundai Ioniq passes over a speed bumps, it is plausible 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 the situation, the parts 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 causes of your noises, to check it, position it under the automobile and apply twists on each of its elements to check that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your vehicle 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 go over a speed bump with your Hyundai Ioniq, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can provoke this squeaking noise. Remember to check by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable 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 Hyundai Ioniq. To change them go to your mechanic.
Other speed bump noise Hyundai Ioniq
If, despite all its assumptions, you still can’t locate the source of the noise your Hyundai Ioniq makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Hyundai Ioniq or to visit your mechanic in order to carry an in-depth check on your Hyundai Ioniq and find this problem.
