Discovering noises from your vehicle frequently is never comforting, so discovering noises on your Hyundai Sonata suspensions when you go over a speed bump can be worrying. This sign may be a sign of a insignificant issue 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 eliminate the issue, it is with this intention 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 Hyundai Sonata
Check Hyundai Sonata suspension
If you notice a suspension noise when you pass a speed bump on your Hyundai Sonata, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin 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 function during small bumps that compress the suspensions. To examine if this is the issue that concerns you, take a dented road and focus on the noise coming from your front axle as you drive 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 “Hyundai Sonata 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion. To examine 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 conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Hyundai Sonata, don’t hesitate to consult this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Hyundai Sonata passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you modify direction. If this is the case, 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 causes of your noises, to examine it, place it under the car and apply twists on each of its components to examine that there is no special play on one of them, they are meant to resist you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or swap them if they are involved.
squeaky noise speed bump Hyundai Sonata
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 Hyundai Sonata, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Bear in mind to examine by passing under your car the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and bring on noise, in which case take them out from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last case that we can examine together, it is the engine silentblocks, actually, these silentblocks function as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise appears when you pass a speed bumps or any holes with your Hyundai Sonata. To change them go to your mechanic.
Other speed bump noise Hyundai Sonata
If, even though all its assumptions, you still can’t uncover the source of the noise your Hyundai Sonata makes when you pass a speed bump, we recommend you to read this article on a loud noise on Hyundai Sonata or to visit your mechanic in order to carry an in-depth check on your Hyundai Sonata and discover this issue.
