We will first see the possible causes 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 807
Check Peugeot 807 suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot 807, 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 In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To verify 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 swapping them fairly quickly or you may ruin other parts and have to make more important auto repairs.
Check the cardan shaft
If you are here because you have looked for for “Peugeot 807 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 old and the dirt/dust accumulates inside them their working is degraded and it is possible to experience a noise when they are in torsion. To verify 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 cases you should consider replacing it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot 807, don’t hesitate to read this document.
Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Peugeot 807 passes over a speed bumps, it is plausible that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you change direction. If this is your situation, the parts that may have been affected by normal wear and tear or impacts (e. g. sidewalks). The steering hinges, the stabilizer bar hinges. can be the origins of your noises, to verify it, put it under the car and apply twists on each of its components to verify that there is no particular play on one of them, they are expected to endure 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 807, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can create this squeaking noise. Please remember to verify by going under your car the condition of the paint on your bar which will show if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and cause noise, in which case remove them from the cradle and grease them, this should resolve the problem.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the automobile, a evident fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Peugeot 807. To change them go to your technician.
