Suspension cracking noise Hyundai Elantra
Check Hyundai Elantra suspension
If you experience a suspension noise when you pass a speed bump on your Hyundai Elantra, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 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 quickly or you may affect other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Hyundai Elantra 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 Indeed, when the cardan bellows get outdated and the dirt/dust builds up inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your Hyundai Elantra passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is the case, the parts that may have been destroyed 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, put it under the car and apply twists on each of its components to check that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your Hyundai Elantra to your auto technician or swap them if they are involved.

Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Hyundai Elantra, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to check by going 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 create 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 check together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a evident fatigue of these will generate 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 Hyundai Elantra. To swap them go to your auto mechanic.
