Discovering noises from your car regularly is never comforting, so listening noises on your Peugeot Boxer suspensions when you pass a speed bump can be stressful.

Whatever the case, it is important 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 help 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 Boxer
Check Peugeot Boxer suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot Boxer, and it is characterized by a “clack” or cracking, it is highly plausible that your suspension block is the cause 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and focus on the noise coming from your front axle as you drive 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 repairs.
Check the cardan shaft
If you are here because you have looked for for “Peugeot Boxer 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 builds up inside them their functions is degraded and it is possible to experience a sound when they are in torsion. To examine 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 situations you should consider replacing it or them.

Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Peugeot Boxer passes over a speed bumps, it is possible 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 case, the components 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 examine it, put it under the automobile and apply twists on each of its elements to examine that there is no special play on one of them, they are expected to endure you quite strongly over their entire travel. Remember to take your vehicle to your auto 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 Boxer, it is plausible that it is the stabilizer bar itself that is concerned. Indeed, abnormal/pronounced wear of the latter can cause unusual friction which can provoke this squeaking noise. Please remember to examine by passing under your automobile 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 dried out and bring on noise, in which case remove them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last point that we can examine together, it is the engine silentblocks, actually, these silentblocks act as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue of these will generate a subsidence and therefore a space between the engine and the silentblocks, it may appear that a squeaking noise comes up when you pass a speed bumps or any holes with your Peugeot Boxer. To change them go to your auto technician.
