Hearing noises from your auto often is never reassuring, so hearing noises on your Peugeot 107 suspensions when you go over a speed bump can be stressing. This sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is important to check the source and take the necessary actions to eliminate the issue, it is with this aim in mind that we wanted to write this document to support you see more clearly. We will first see the possible explanations 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 Peugeot 107
Check Peugeot 107 suspension
If you notice a suspension noise when you pass a speed bump on your Peugeot 107, and it is categorized by a “clack” or cracking, it is highly possible that your suspension block is the cause of it. In fact, 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 issue 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 changing them fairly quickly or you may affect other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Peugeot 107 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 circumstances you should consider swapping it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot 107, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Peugeot 107 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Just like the gimbals, the steering part is mobilized when you adjust direction. If this is the situation, the components that may have been affected by regular 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, put it under the automobile 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. Keep in mind to take your vehicle to your technician or change them if they are involved.

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 Peugeot 107, it is possible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Remember to check by passing under your automobile 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 bring on noise, in which case take them off from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point that we can check together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the auto, a noticable weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise occurs when you pass a speed bumps or any holes with your Peugeot 107. To change them go to your auto mechanic.
