Suspension cracking noise Peugeot 306
Check Peugeot 306 suspension
If you encounter a suspension noise when you pass a speed bump on your Peugeot 306, and it is characterized by a “clack” or cracking, it is highly possible that your suspension block is the origin of it. In fact, it may be the suspension cups, which, when they are outdated, have the rubber (silentblock) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its job during small bumps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 problem that concerns you, take a dented road and focus on the noise coming from your front axle as you go over holes. If it is indeed the cups, think of swapping them fairly 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 306 suspension noise” and the suspension is not the cause of your problem, it may be that the cardan shaft is responsible. In fact, when the cardan bellows get outdated and the dirt/dust amasses inside them their operation is deteriorated and it is possible to experience a sound when they are in torsion.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 make a turn at low speed. If it cracks in these two circumstances you should consider changing it or them.

Check steering hinges/stabilizer bar
Finally, when you find out a suspension noise when your Peugeot 306 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 modify direction. If this is your situation, the parts that may have been damaged 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 examine it, place it under the automobile and apply twists on each of its elements to examine that there is no particular play on one of them, they are meant to resist 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, on the other hand, you have a noise that is more like a squeak when you pass a speed bump with your Peugeot 306, it is possible that it is the stabilizer bar itself that is concerned. In fact, abnormal/pronounced wear of the latter can cause abnormal friction which can cause this squeaking noise. Remember to examine by passing under your automobile the condition of the paint on your bar which will indicate if there is friction. Second possible point, it may be your stabilizer bar silentblocks that are dry and cause noise, in which case take them out from the cradle and grease them, this should eliminate the problem.
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 vehicle, a evident weakness of these will make a subsidence and therefore a space between the engine and the silentblocks, it may happen that a squeaking noise happens when you pass a speed bumps or any holes with your Peugeot 306. To swap them go to your mechanic.
