Finding out noises from your vehicle regularly is never reassuring, so hearing noises on your Kia E Niro suspensions when you pass a speed bump can be disturbing. This symptom may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin 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 causes 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 E Niro
Check Kia E Niro suspension
If you notice a suspension noise when you pass a speed bump on your Kia E Niro, and it is characterized 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 role 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 swapping them fairly quickly or you may damage other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “Kia E 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is degraded and it is possible to experience a sound when they are in torsion.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 cases you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Kia E Niro, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Kia E Niro 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 change direction. If this is the case, the parts that may have been affected 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 components to check that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Please remember to take your Kia E Niro to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Kia E Niro
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Kia E Niro, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Bear in mind to check by passing under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case disassemble them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a evident fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Kia E Niro. To swap them go to your technician.
Other speed bump noise Kia E Niro
If, despite all its assumptions, you still can’t uncover the origin of the noise your Kia E Niro makes when you pass a speed bump, we suggest you to read this content on a loud noise on Kia E Niro or to visit your auto mechanic in order to carry an in-depth check on your Kia E Niro and identify this issue.
