Suspension cracking noise Peugeot 307
Check Peugeot 307 suspension
If you notice a suspension noise when you pass a speed bump on your Peugeot 307, and it is categorized by a “clack” or cracking, it is highly possible 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 Indeed, it may be the suspension cups, which, when they are out of date, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps that compress the suspensions. To examine if this is the issue that worries you, take a dented road and pay attention to the noise coming from your front axle as you pass over holes. If it is indeed the cups, think of changing 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 307 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 Indeed, when the cardan bellows get out of date and the dirt/dust amasses inside them their functions is degraded and it is possible to experience a noise when they are in torsion.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 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 307, don’t hesitate to visit this document.
Check steering hinges/stabilizer bar
Finally, when you recognise a suspension noise when your Peugeot 307 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 case, the components that may have been affected 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 examine it, place it under the vehicle and apply twists on each of its components to examine that there is no special play on one of them, they are supposed to endure you quite strongly over their entire travel. Keep in mind to take your Peugeot 307 to your auto technician or replace them if they are involved.

Check the stabilizer bar
If, on the other hand, you have a noise that is more like a squeak when you go over a speed bump with your Peugeot 307, it is possible that it is the stabilizer bar itself that is involved. Indeed, abnormal/pronounced wear of the latter can cause irregular friction which can generate this squeaking noise. Keep in mind to examine by passing under your vehicle the condition of the paint on your bar which will tell us if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dried out and provoke noise, in which case disassemble them from the cradle and grease them, this should fix the issue.
Check engine silentblocks
Finally, last possibility that we can examine together, it is the engine silentblocks, actually, these silentblocks process as pads/shock absorbers between the engine and the cradle of the car, a pronounced fatigue 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 307. To replace them go to your auto mechanic.
