Check your high engine
If you notice a clicking noise on Peugeot 406, and this noise is located at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two elements can be the triggers of these ticking noises on Peugeot 406. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will perceive these clicking noises, generally when cold and vanish 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.
Check your low engine
If you have distinguished the region of origin of the Peugeot 406 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both circumstances, the risk in the long term is the breakage of the motor. These two fixes are very difficult and most mechanics will recommend you to change the engine of your Peugeot 406.
Combustion problem
Finally, if you have the feeling that this clicking noise on Peugeot 406 is linked to the combustion of your engine, there are three possible reasons of it. Check the condition of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is conceivable that your timing belt is shifted and that it does not properly manage the timing of the various engine parts to promote good combustion. And finally, the most classic cause, comes from your injection, which is either blocked or one or more injectors are damaged. In this circumstance, do not hesitate to read this document which deals in detail with the different injection sounds on Peugeot 406.

Check the condition of the gimbals
One of the most regular reasons of a clicking noises in the direction of your Peugeot 406 is associated with the direction of the car. 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 make a ticking type of sound when you get closer to the stop zone of your steering. A bellows with holes will damage 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.

Check the rest of your direction
Finally, when you detect a clicking noise on your Peugeot 406, it is conceivable 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 circumstance, 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 notice a clicking noise on Peugeot 406 coming from my suspensions
Check the suspension
If you experience a clicking noise on your Peugeot 406 once you pass a speed bump, it is extremely conceivable that your suspension block is the induce of the noise. Indeed, it may be the suspension cups, which, when they are dead, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its role 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, focus on the noise originating from your front axle when ever you pass over holes. If these are the cups, consider changing them quickly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you detect a clicking noise on your Peugeot 406 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a cause. To verify the condition of the spring, place the automobile 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 means that most likely your springs are worn, if you find out a leak go a little further in the article to have the answer to this problem. For the cylinder the verification is visual, ensure 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 406 than a clicking noise, don’t hesitate to consult this article.
