Finding out noises from your car frequently is never reassuring, so discovering noises on your Kia Rio suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a minor problem as well as a warning of a much larger repair to come. Whatever the case, it is important to check the origin and take the necessary actions to solve the problem, it is with this goal in mind that we wanted to write this document to support you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, 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 Kia Rio
Check Kia Rio suspension
If you encounter a suspension noise when you pass a speed bump on your Kia Rio, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the cause of it. Indeed, 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 problem that worries you, take a dented road and focus on the noise coming from your front axle as you go 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 vehicle repairs.
Check the cardan shaft
If you are here because you have looked for for “Kia Rio 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 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 situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Kia Rio, don’t hesitate to visit this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Kia Rio passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is the situation, the components that may have been broken 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, place it under the car and apply twists on each of its components to check that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Please remember to take your Kia Rio to your mechanic or swap them if they are involved.
squeaky noise speed bump Kia Rio
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Kia Rio, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Bear in mind to check by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them off from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the car, a pronounced weakness of these will make 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 Rio. To swap them go to your auto technician.
Other speed bump noise Kia Rio
If, even though all its assumptions, you still can’t find the source of the noise your Kia Rio makes when you pass a speed bump, we advise you to read this content on a loud noise on Kia Rio or to visit your mechanic in order to carry an in-depth check on your Kia Rio and determine this problem.
