In any case, it is essential to check the cause and take the necessary actions to correct the problem, it is with this intention in mind that we wanted to write this article to help you see more clearly. 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-noise-peugeot-4007

Suspension cracking noise Peugeot 4007

Check Peugeot 4007 suspension

If you notice a suspension noise when you pass a speed bump on your Peugeot 4007, and it is characterized 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 old, 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 problem that concerns you, take a dented road and listen to 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 auto repairs.

Check the cardan shaft

If you are here because you have searched for “Peugeot 4007 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 Indeed, when the cardan bellows get out of date and the dirt/dust accumulates inside them their action is deteriorated and it is possible to experience a sound when they are in torsion.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 cases you should consider changing it or them.

Check steering hinges/stabilizer bar

Finally, when you experience a suspension noise when your Peugeot 4007 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 vary direction. If this is the case, 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 car 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. Keep in mind to take your Peugeot 4007 to your technician 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 pass a speed bump with your Peugeot 4007, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause uncommon friction which can generate this squeaking noise. Bear in mind to check by going under your car 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 create noise, in which case disassemble them from the cradle and grease them, this should eliminate the problem.

Check engine silentblocks

Finally, last case that we can check together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the automobile, a obvious weakness of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise shows up when you pass a speed bumps or any holes with your Peugeot 4007. To change them go to your technician.

Other speed bump noise Peugeot 4007

If, even though all its assumptions, you still can’t find the source of the noise your Peugeot 4007 makes when you pass a speed bump, we recommend you to consult this article on a loud noise on Peugeot 4007 or to visit your technician in order to carry an in-depth check on your Peugeot 4007 and discover this problem.
