Listening noises from your automobile frequently is never reassuring, so listening noises on your Fiat Doblo Cargo suspensions when you go over a speed bump can be stressful. This symptom may be a sign of a insignificant problem 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 eliminate the problem, it is with this goal in mind that we wanted to write this document to help 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 Doblo Cargo
Check Fiat Doblo Cargo suspension
If you encounter a suspension noise when you pass a speed bump on your Fiat Doblo Cargo, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are dead, 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 check if this is the problem that concerns you, take a dented road and listen to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing them fairly quickly or you may ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have searched for “Fiat Doblo Cargo 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 old and the dirt/dust amasses inside them their functions is degraded 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 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 detect a suspension noise when your Fiat Doblo Cargo 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 case, the parts that may have been damaged 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 check it, place it under the vehicle and apply twists on each of its components to check that there is no special 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 swap them if they are involved.
squeaky noise speed bump Fiat Doblo Cargo
Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you go over a speed bump with your Fiat Doblo Cargo, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Bear in mind to check by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case remove them from the cradle and grease them, this should eliminate the problem.
Check engine silentblocks
Finally, last case that we can check together, it is the engine silentblocks, in fact, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will create 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 Doblo Cargo. To swap them go to your technician.
Other speed bump noise Fiat Doblo Cargo
If, despite all its assumptions, you still can’t find the origin of the noise your Fiat Doblo Cargo makes when you pass a speed bump, we encourage you to read this content on a loud noise on Fiat Doblo Cargo or to visit your mechanic in order to carry an in-depth check on your Fiat Doblo Cargo and determine this problem.
