Experiencing noises from your auto often is never reassuring, so discovering noises on your Fiat Stilo suspensions when you pass a speed bump can be disturbing. This indicator may be a sign of a minor issue as well as a warning of a much larger repair to come. In any case, it is necessary to check the origin and take the necessary actions to solve the issue, it is with this goal 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, then, 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 Stilo
Check Fiat Stilo suspension
If you encounter a suspension noise when you pass a speed bump on your Fiat Stilo, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, 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 function during small bumps that compress the suspensions. To examine if this is the issue 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 as soon as possible 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 researched for “Fiat Stilo 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 In fact, when the cardan bellows get outdated and the dirt/dust accumulates inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion. To examine 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 situations you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Fiat Stilo passes over a speed bumps, it is plausible 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 situation, the components that may have been affected 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 examine it, position it under the vehicle and apply twists on each of its elements to examine that there is no particular play on one of them, they are expected to endure you quite strongly over their entire travel. Please remember to take your vehicle to your mechanic or replace them if they are involved.
squeaky noise speed bump Fiat Stilo
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you pass a speed bump with your Fiat Stilo, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can cause this squeaking noise. Please remember to examine by going under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them off from the cradle and grease them, this should resolve the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the auto, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Fiat Stilo. To replace them go to your auto mechanic.
Other speed bump noise Fiat Stilo
If, even though all its assumptions, you still can’t uncover the source of the noise your Fiat Stilo makes when you pass a speed bump, we recommend you to read this article on a loud noise on Fiat Stilo or to visit your mechanic in order to carry an in-depth check on your Fiat Stilo and find this issue.
