Listening noises from your vehicle regularly is never comforting, so hearing noises on your Kia Soul suspensions when you go over a speed bump can be stressing. This warning sign may be a sign of a minor trouble as well as a warning of a much larger repair to come. In any case, it is necessary to check the source and take the necessary actions to solve the trouble, it is with this aim in mind that we wanted to write this content to support 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 Soul
Check Kia Soul suspension
If you experience a suspension noise when you pass a speed bump on your Kia Soul, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 trouble that worries you, take a dented road and listen to the noise coming from your front axle as you pass 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 fixes.
Check the cardan shaft
If you are here because you have searched for “Kia Soul 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 turn at low speed. If it cracks in these two circumstances you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Kia Soul, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Kia Soul 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 vary direction. If this is your situation, the components that may have been destroyed by normal 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, put it under the vehicle 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. Remember to take your Kia Soul to your auto technician or replace them if they are involved.
squeaky noise speed bump Kia Soul
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Kia Soul, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can provoke this squeaking noise. Please 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 bring on noise, in which case take them off from the cradle and grease them, this should fix the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, in fact, these silentblocks function 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 Kia Soul. To change them go to your auto mechanic.
Other speed bump noise Kia Soul
If, even though all its assumptions, you still can’t find the origin of the noise your Kia Soul makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Kia Soul or to visit your auto technician in order to carry an in-depth check on your Kia Soul and find this trouble.
