Being subject to constant noise on your vehicle tends to be frustrating, a vehicle is so sophisticated that it is generally difficult to locate its origin and even more so to find the part that produces it. If you have already experienced a clicking noise on your Peugeot 407, we will almost certainly be able to support you. Indeed, our editorial staff decided to create this document in order to review the main causes of a clicking noise on Peugeot 407. This is why, firstly, we will see what are the causes of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the sources of clicking noise on Peugeot 407 coming from your suspensions.
I discover a clicking noise on Peugeot 407 on my engine
Examine your high engine
If you discover a clicking noise on Peugeot 407, and this sound is located at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Peugeot 407. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally when cold and disappear when hot. Otherwise, it is the interplay of your rocker arms or their condition of wear that is at issue. In this situation, remember to change them.
Examine your low engine
If you have identified the area of origin of the Peugeot 407 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both cases, the risk in the long term is the breakage of the motor. These two fixes are very complex and most mechanics will suggest you to change the engine of your Peugeot 407.
Combustion problem
Finally, if you have the feeling that this clicking noise on Peugeot 407 is connected to the combustion of your engine, there are three possible origins of it. Examine the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is plausible that your timing belt is shifted and that it does not properly manage the timing of the various engine components to promote good combustion. And finally, the most classic trigger, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to check this document which deals in detail with the different injection sounds on Peugeot 407.
I discover a clicking noise on Peugeot 407 in my direction
Examine the condition of the gimbals
One of the most regular reasons of a clicking noises in the direction of your Peugeot 407 is associated with the direction of the vehicle. Indeed, the cardans and their bellows are parts that are constantly stressed during your changes of direction or that you turn your wheels and a wear of one of them can generate a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be swapped rapidly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it. If you would like more detailed information about gimbals noises on Peugeot 407, do not hesitate to consult this complete guide.
Examine the rest of your direction
Finally, when you recognise a clicking noise on your Peugeot 407, it is plausible that it is the direction that is involved. Just like the gimbals, the steering part is mobilized when you turn your wheels. If this is the case, the parts that may have been damaged due to normal wear and tear or impact (e. g. sidewalks) are steering rods, stabilizer bar silentblocks or steering triangles.
I discover a clicking noise on Peugeot 407 coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Peugeot 407 when you pass a speed bump, it is highly plausible that your suspension block is the induce of the sound. Indeed, it may be the suspension cups, which, when they are outdated, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To verify if this is the issue that worries you, take a dented road and, at low speed, listen to the sound coming from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Peugeot 407 at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a explanation. To verify the shape of the spring, position the car on a flat surface and measure that the heights from the ground to the bottom of the body are identical on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you observe a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, make sure that it seems to work in a straight axis. And that there is no angle that would alter its proper functioning. If one of them breaks in both situations, you should consider swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Peugeot 407 than a clicking noise, don’t hesitate to consult this article.
