Listening noises from your car regularly is never reassuring, so listening noises on your Fiat Grande Punto suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a small problem as well as a warning of a much larger repair to come. Whatever the case, it is fundamental to check the origin and take the necessary actions to resolve the problem, it is with this intention in mind that we wanted to write this article to help you see more clearly. We will first see the possible reasons for a crack when the speed bump passes, then, what can be the reason 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 Grande Punto
Check Fiat Grande Punto suspension
If you encounter a suspension noise when you pass a speed bump on your Fiat Grande Punto, 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 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 role during small bumps that compress the suspensions. To examine if this is the problem that worries you, take a dented road and pay attention to the noise coming from your front axle as you drive over holes. If it is indeed the cups, think of swapping them fairly quickly or you may damage other parts and have to make more important repairs.
Check the cardan shaft
If you are here because you have searched for “Fiat Grande Punto 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 In fact, when the cardan bellows get outdated and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Fiat Grande Punto passes over a speed bumps, it is plausible 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 broken by regular 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, place it under the vehicle and apply twists on each of its components to examine 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 vehicle to your auto mechanic or replace them if they are involved.
squeaky noise speed bump Fiat Grande Punto
Check the stabilizer bar
If, however, you have a noise that is more like a squeak when you go over a speed bump with your Fiat Grande Punto, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to examine by going under your vehicle the condition of the paint on your bar which will show if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a obvious fatigue of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Fiat Grande Punto. To change them go to your auto mechanic.

If, despite all its assumptions, you still can’t locate the source of the noise your Fiat Grande Punto makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Fiat Grande Punto or to visit your auto mechanic in order to carry an in-depth check on your Fiat Grande Punto and discover this problem.
