Experiencing noises from your car often is never reassuring, so discovering noises on your Kia Sedona suspensions when you pass a speed bump can be disturbing. This sign 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 necessary to check the cause and take the necessary actions to solve the problem, it is with this aim in mind that we wanted to write this article 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 Sedona
Check Kia Sedona suspension
If you notice a suspension noise when you pass a speed bump on your Kia Sedona, and it is characterized 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of changing them fairly quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Kia Sedona 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 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 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 Sedona, don’t hesitate to check out this article.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Kia Sedona 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 case, the components that may have been broken by regular 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 elements 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 vehicle to your technician or swap them if they are involved.

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 Sedona, 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. Remember to check by going under your car the condition of the paint on your bar which will indicate if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them off from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Kia Sedona. To swap them go to your mechanic.
Other speed bump noise Kia Sedona
If, even though all its assumptions, you still can’t locate the origin of the noise your Kia Sedona makes when you pass a speed bump, we recommend you to refer to this article on a loud noise on Kia Sedona or to visit your technician in order to carry an in-depth check on your Kia Sedona and find this problem.
