Suspension cracking noise hyundai i30
Check hyundai i30 suspension
If you experience a suspension noise when you pass a speed bump on your hyundai i30, and it is categorized by a “clack” or cracking, it is highly plausible 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps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 go over holes. If it is indeed the cups, think of replacing them fairly quickly or you may ruin other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have searched for “hyundai i30 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a noise when they are in torsion.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 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 turn at low speed. If it cracks in these two conditions you should consider swapping it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your hyundai i30 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 your situation, the components that may have been affected by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the causes of your noises, to verify it, place it under the car and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your vehicle to your auto technician or change them if they are involved.
squeaky noise speed bump hyundai i30
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your hyundai i30, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can create this squeaking noise. Please remember to verify by going under your car 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 dry and cause noise, in which case remove them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can verify together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the vehicle, a noticable fatigue 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 hyundai i30. To change them go to your auto mechanic.
