Finding out noises from your vehicle often is never reassuring, so hearing noises on your Peugeot 607 suspensions when you go over a speed bump can be stressful. This indicator may be a sign of a minor trouble as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the origin and take the necessary actions to solve the trouble, it is with this aim 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, then, 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 607
Check Peugeot 607 suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot 607, and it is categorized by a “clack” or cracking, it is highly plausible that your suspension block is the origin of it. Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its function during small bumps that compress the suspensions. To verify if this is the trouble 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 as soon as possible or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have looked for for “Peugeot 607 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their operation is degraded and it is possible to experience a noise when they are in torsion.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 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 607, don’t hesitate to refer to this document.
Check steering hinges/stabilizer bar
Finally, when you know a suspension noise when your Peugeot 607 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 change direction. If this is the situation, the components that may have been damaged 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, position it under the vehicle and apply twists on each of its elements to verify 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 auto mechanic or swap them if they are involved.
squeaky noise speed bump Peugeot 607
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 607, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can create this squeaking noise. Please remember to verify by passing under your vehicle the condition of the paint on your bar which will indicate if there is friction. Second plausible point, it may be your stabilizer bar silentblocks that are dried out and create noise, in which case take them off from the cradle and grease them, this should resolve the trouble.
Check engine silentblocks
Finally, last case that we can verify together, it is the engine silentblocks, actually, these silentblocks operate as pads/shock absorbers between the engine and the cradle of the vehicle, a obvious weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise comes up when you pass a speed bumps or any holes with your Peugeot 607. To replace them go to your auto mechanic.
Other speed bump noise Peugeot 607
If, despite all its assumptions, you still can’t locate the source of the noise your Peugeot 607 makes when you pass a speed bump, we suggest you to refer to this content on a loud noise on Peugeot 607 or to visit your auto mechanic in order to carry an in-depth check on your Peugeot 607 and identify this trouble.
