Experiencing noises from your automobile often is never reassuring, so discovering noises on your Kia Niro suspensions when you go over a speed bump can be worrying. This symptom 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 fundamental to check the source and take the necessary actions to solve the problem, it is with this objective in mind that we wanted to write this article 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 Kia Niro
Check Kia Niro suspension
If you encounter a suspension noise when you pass a speed bump on your Kia Niro, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To check 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 pass over holes. If it is indeed the cups, think of swapping them quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have looked for for “Kia Niro 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 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 Kia Niro, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Kia Niro passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you vary direction. If this is the situation, the parts that may have been affected 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 check it, place it under the car and apply twists on each of its elements to check that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto technician or swap 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 Kia Niro, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Please remember to check by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the automobile, a pronounced weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Kia Niro. To change them go to your mechanic.
