Discovering noises from your automobile frequently is never reassuring, so hearing noises on your Kia Sportage suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to solve the issue, it is with this objective 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 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 Sportage
Check Kia Sportage suspension
If you encounter a suspension noise when you pass a speed bump on your Kia Sportage, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the cause 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Kia Sportage 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 old and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion. To verify 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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Kia Sportage, don’t hesitate to read this article.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Kia Sportage 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 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 verify it, place it under the automobile and apply twists on each of its components to verify that there is no special play on one of them, they are meant to endure you quite strongly over their entire travel. Remember to take your Kia Sportage to your technician or swap them if they are involved.
squeaky noise speed bump Kia Sportage
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 Sportage, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Keep in mind to verify by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them out from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, actually, these silentblocks work 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 occurs when you pass a speed bumps or any holes with your Kia Sportage. To replace them go to your technician.
Other speed bump noise Kia Sportage
If, despite all its assumptions, you still can’t locate the origin of the noise your Kia Sportage makes when you pass a speed bump, we advise you to read this article on a loud noise on Kia Sportage or to visit your technician in order to carry an in-depth check on your Kia Sportage and find this issue.
