Finding out noises from your vehicle regularly is never reassuring, so discovering noises on your Fiat Ducato suspensions when you pass a speed bump can be stressful. This sign may be a sign of a small issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to resolve the issue, it is with this objective in mind that we wanted to write this document to help you see more clearly. We will first see the possible reasons 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 Ducato
Check Fiat Ducato suspension
If you experience a suspension noise when you pass a speed bump on your Fiat Ducato, and it is categorized 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To check if this is the issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them as soon as possible or you may affect other parts and have to make more important vehicle repairs.
Check the cardan shaft
If you are here because you have researched for “Fiat Ducato 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a noise when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Fiat Ducato, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Fiat Ducato passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the components that may have been destroyed by usual wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to check it, place it under the vehicle and apply twists on each of its elements to check that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your vehicle to your technician or change 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 Ducato, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can generate this squeaking noise. Keep in mind to check 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 dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should solve the issue.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise shows up when you pass a speed bumps or any holes with your Fiat Ducato. To replace them go to your mechanic.
