In any case, it is essential to check the cause and take the necessary actions to correct the problem, it is with this goal in mind that we wanted to write this content to support 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 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 207
Check Peugeot 207 suspension
If you notice a suspension noise when you pass a speed bump on your Peugeot 207, 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 In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 circulate over holes. If it is indeed the cups, think of replacing them quickly or you may damage other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have searched for “Peugeot 207 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 In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their working is deteriorated and it is possible to experience a sound when they are in torsion.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 situations you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot 207, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Peugeot 207 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 the case, 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 particular 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 auto mechanic or replace them if they are involved.

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 Peugeot 207, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Please remember to check by passing 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 dried out and create noise, in which case remove them from the cradle and grease them, this should solve the problem.
Check engine silentblocks
Finally, last possibility that we can check together, it is the engine silentblocks, in fact, these silentblocks work as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise occurs when you pass a speed bumps or any holes with your Peugeot 207. To swap them go to your auto mechanic.

If, despite all its assumptions, you still can’t uncover the origin of the noise your Peugeot 207 makes when you pass a speed bump, we advise you to refer to this content on a loud noise on Peugeot 207 or to visit your auto mechanic in order to carry an in-depth check on your Peugeot 207 and discover this problem.
