Finding out noises from your vehicle regularly is never comforting, so hearing noises on your Peugeot 806 suspensions when you go over a speed bump can be stressful. This warning sign may be a sign of a insignificant issue as well as a warning of a much larger repair to come. In any case, it is fundamental to check the origin and take the necessary actions to resolve the issue, it is with this intention in mind that we wanted to write this article 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 806
Check Peugeot 806 suspension
If you notice a suspension noise when you pass a speed bump on your Peugeot 806, and it is characterized by a “clack” or cracking, it is highly plausible 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 verify if this is the issue 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 swapping them quickly or you may affect other parts and have to make more important maintenance.
Check the cardan shaft
If you are here because you have researched for “Peugeot 806 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 In fact, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is deteriorated and it is possible to experience a sound when they are in torsion.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 changing it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot 806, don’t hesitate to read this content.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Peugeot 806 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 modify direction. If this is the case, the parts 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 causes of your noises, to verify it, put it under the car and apply twists on each of its elements to verify that there is no particular play on one of them, they are supposed to endure you quite strongly over their entire travel. Remember to take your Peugeot 806 to your technician or swap 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 806, it is plausible that it is the stabilizer bar itself that is involved. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Bear in mind to verify by passing under your car the condition of the paint on your bar which will reveal if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should solve the issue.
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 vehicle, a pronounced fatigue of these will make 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 806. To change them go to your auto technician.
Other speed bump noise Peugeot 806
If, even though all its assumptions, you still can’t find the origin of the noise your Peugeot 806 makes when you pass a speed bump, we suggest you to consult this content on a loud noise on Peugeot 806 or to visit your technician in order to carry an in-depth check on your Peugeot 806 and discover this issue.
