Experiencing noises from your vehicle frequently is never comforting, so hearing noises on your Fiat 500 L suspensions when you go over a speed bump can be worrying. This sign may be a sign of a insignificant problem as well as a warning of a much larger repair to come. Whatever the case, it is necessary to check the source and take the necessary actions to eliminate the problem, it is with this objective in mind that we wanted to write this article to support you see more clearly. We will first see the possible explanations for a crack when the speed bump passes, after that, what can be the cause 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 Fiat 500 L
Check Fiat 500 L suspension
If you experience a suspension noise when you pass a speed bump on your Fiat 500 L, and it is characterized 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To verify if this is the problem that concerns you, take a dented road and focus on the noise coming from your front axle as you circulate over holes. If it is indeed the cups, think of swapping them fairly quickly or you may ruin other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have searched for “Fiat 500 L 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 In fact, when the cardan bellows get out of date and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a sound when they are in torsion.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 L, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Fiat 500 L passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Exactly like the gimbals, the steering part is mobilized when you vary direction. If this is the situation, the components that may have been destroyed by normal 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, position 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 expected to resist you quite strongly over their entire travel. Please remember to take your Fiat 500 L to your mechanic or swap them if they are involved.
squeaky noise speed bump Fiat 500 L
Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Fiat 500 L, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can create this squeaking noise. Keep in mind to verify by going under your car the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and create noise, in which case take them out from the cradle and grease them, this should fix the problem.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious fatigue 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 Fiat 500 L. To replace them go to your auto mechanic.
Other speed bump noise Fiat 500 L
If, despite all its assumptions, you still can’t uncover the origin of the noise your Fiat 500 L makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Fiat 500 L or to visit your mechanic in order to carry an in-depth check on your Fiat 500 L and identify this problem.
