Suspension cracking noise seat leon
Check seat leon suspension
If you encounter a suspension noise when you pass a speed bump on your seat leon, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 verify if this is the trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of replacing them 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 “seat leon 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 old and the dirt/dust builds up inside them their operation is deteriorated and it is possible to experience a sound 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 situations you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on seat leon, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you detect a suspension noise when your seat leon passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust 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 verify it, place it under the vehicle 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. Remember to take your seat leon to your auto mechanic or change them if they are involved.
squeaky noise speed bump seat leon
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 seat leon, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Keep in mind to verify by passing under your vehicle 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 dried out and cause noise, in which case take them off from the cradle and grease them, this should eliminate the trouble.
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 auto, a pronounced weakness of these will make 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 seat leon. To change them go to your auto mechanic.
