Suspension cracking noise Fiat Doblo 2
Check Fiat Doblo 2 suspension
If you experience a suspension noise when you pass a speed bump on your Fiat Doblo 2, and it is categorized by a “clack” or cracking, it is highly plausible 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 job during small bumps that compress the suspensions. To check if this is the issue that concerns 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 ruin other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Fiat Doblo 2 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 In fact, when the cardan bellows get out of date and the dirt/dust builds up inside them their working is deteriorated and it is possible to experience a noise when they are in torsion.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 turn at low speed. If it cracks in these two conditions you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Fiat Doblo 2 passes over a speed bumps, it is possible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you vary direction. If this is your situation, 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, put it under the automobile and apply twists on each of its elements to check that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Keep in mind to take your Fiat Doblo 2 to your auto technician or replace them if they are involved.

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 Doblo 2, it is plausible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Bear in mind to check by going under your automobile the condition of the paint on your bar which will show if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case disassemble them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last case 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 automobile, a evident fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise happens when you pass a speed bumps or any holes with your Fiat Doblo 2. To replace them go to your auto mechanic.
