Listening noises from your auto often is never reassuring, so hearing noises on your Fiat Punto suspensions when you pass a speed bump can be stressful. This sign may be a sign of a small trouble as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the source and take the necessary actions to eliminate the trouble, 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, 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 Punto
Check Fiat Punto suspension
If you notice a suspension noise when you pass a speed bump on your Fiat Punto, 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 trouble that concerns you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of replacing them as soon as possible or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Fiat Punto 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 Indeed, when the cardan bellows get outdated and the dirt/dust accumulates inside them their operation is deteriorated and it is possible to experience a noise when they are in torsion.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 cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Fiat Punto, don’t hesitate to check out this document.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Fiat Punto 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 change direction. If this is the situation, the parts that may have been damaged 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 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 Fiat Punto to your auto technician or replace them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Fiat Punto, it is possible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Please remember to check by going 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 dry and bring on noise, in which case remove them from the cradle and grease them, this should solve the trouble.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the auto, a noticable fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Fiat Punto. To swap them go to your technician.
