Listening noises from your vehicle frequently is never comforting, so listening noises on your Peugeot Expert suspensions when you pass a speed bump can be stressful. This indicator may be a sign of a insignificant issue as well as a warning of a much larger repair to come. Whatever the case, it is essential to check the source and take the necessary actions to eliminate the issue, it is with this objective in mind that we wanted to write this document 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 Expert
Check Peugeot Expert suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot Expert, 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 job during small bumps that compress the suspensions. To verify if this is the issue that worries 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 swapping them quickly or you may damage other parts and have to make more important fixes.
Check the cardan shaft
If you are here because you have researched for “Peugeot Expert 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 old and the dirt/dust amasses 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 conditions you should consider changing it or them. If you have the feeling that this noise is more like a a loud noise on Peugeot Expert, don’t hesitate to refer to this article.
Check steering hinges/stabilizer bar
Finally, when you experience a suspension noise when your Peugeot Expert passes over a speed bumps, it is imaginable that the hinges or the stabilizer bar are responsible. Simply like the gimbals, the steering part is mobilized when you adjust direction. If this is the 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 causes of your noises, to verify it, place it under the automobile and apply twists on each of its components to verify that there is no special play on one of them, they are supposed to resist you quite strongly over their entire travel. Remember to take your vehicle to your auto 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 Expert, it is plausible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Please remember to verify by passing under your automobile the condition of the paint on your bar which will reveal if there is friction. Second plausible explanation, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case take them out from the cradle and grease them, this should eliminate the issue.
Check engine silentblocks
Finally, last point that we can verify together, it is the engine silentblocks, actually, these silentblocks work as pads/shock absorbers between the engine and the cradle of the vehicle, a evident fatigue of these will create a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise appears when you pass a speed bumps or any holes with your Peugeot Expert. To swap them go to your mechanic.
