In any case, it is essential to check the source and take the necessary actions to eliminate the issue, it is with this intention 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 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 Peugeot 108
Check Peugeot 108 suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot 108, and it is categorized by a “clack” or cracking, it is highly plausible 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 Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small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 concerns you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of replacing them 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 looked for for “Peugeot 108 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 Indeed, when the cardan bellows get outdated and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot 108, don’t hesitate to consult this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Peugeot 108 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 change direction. If this is your situation, the components 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 origins 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 resist you quite strongly over their entire travel. Remember to take your vehicle to your mechanic or change them if they are involved.

Check the stabilizer bar
If, alternatively, you have a noise that is more like a squeak when you pass a speed bump with your Peugeot 108, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause abnormal friction which can generate this squeaking noise. Remember to check 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 bring on noise, in which case take them out from the cradle and grease them, this should eliminate the issue.
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 pronounced weakness of these will make 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 Peugeot 108. To replace them go to your mechanic.
Other speed bump noise Peugeot 108
If, despite all its assumptions, you still can’t locate the origin of the noise your Peugeot 108 makes when you pass a speed bump, we recommend you to refer to this content on a loud noise on Peugeot 108 or to visit your mechanic in order to carry an in-depth check on your Peugeot 108 and determine this issue.
