Suspension cracking noise Fiat 500

Check Fiat 500 suspension

If you encounter a suspension noise when you pass a speed bump on your Fiat 500, and it is characterized 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 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 job during small bumps that compress the suspensions. To verify if this is the trouble 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 changing them quickly or you may affect other parts and have to make more important maintenance.

Check the cardan shaft

If you are here because you have looked for for “Fiat 500 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 Indeed, when the cardan bellows get out of date and the dirt/dust builds up inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Fiat 500, don’t hesitate to read this content.

Check steering hinges/stabilizer bar

Finally, when you detect a suspension noise when your Fiat 500 passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you adjust direction. If this is the case, the parts 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 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 meant 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.

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 Fiat 500, 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 generate this squeaking noise. Keep in mind to verify by passing under your car the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and bring on 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, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the auto, a evident fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Fiat 500. To replace them go to your auto mechanic.

If, despite all its assumptions, you still can’t uncover the origin of the noise your Fiat 500 makes when you pass a speed bump, we recommend you to read this article on a loud noise on Fiat 500 or to visit your auto technician in order to carry an in-depth check on your Fiat 500 and determine this trouble.
