I notice a clicking noise on Mercedes Actros on my engine
Check your high engine
If you notice a clicking noise on Mercedes Actros, and this sound is located at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two elements can be the causes of these ticking noises on Mercedes Actros. Either the hydraulic pushers , in general it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, generally when cold and go away when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this situation, remember to change them.
Check your low engine
If you have identified the area of source of the Mercedes Actros clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two maintenance are very difficult and most mechanics will suggest you to change the engine of your Mercedes Actros.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Actros is linked to the combustion of your engine, there are three possible causes of it. Check the state of your glow plugs which, if worn, can hinder the proper combustion of the fuel mixture. Then, it is possible that your timing belt is shifted and that it does not properly manage the timing of the various engine elements to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are destroyed. In this circumstance, do not hesitate to check this document which deals in detail with the different injection sounds on Mercedes Actros.
I notice a clicking noise on Mercedes Actros in my direction
Check the state of the gimbals
One of the most basic triggers of a clicking noises in the direction of your Mercedes Actros is linked to 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 approach the stop zone of your steering. A bellows with holes will affect the cardan shaft very quickly and must be changed very quickly, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it.

Check the rest of your direction
Finally, when you know a clicking noise on your Mercedes Actros, it is possible 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.

Check the suspension
If you encounter a clicking noise on your Mercedes Actros when you pass a speed bump, it is highly possible that your suspension block is the cause of the sound. In fact, 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, listen to the sound originating from your front axle when 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 are subject to a clicking noise on your Mercedes Actros at the suspension level, it is highly possible that spring wear or shock cylinder deformation may be a explanation. To verify the state 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 equivalent on each side (empty car for measurement). You can also verify between the front and rear, if there is a gap too large it suggests that that most likely your springs are worn, if you find out a leak go a little further in the article to have the solution to this problem. For the cylinder the verification is visual, be 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 think about swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Actros than a clicking noise, don’t hesitate to consult this article.
