I discover a clicking noise on Mercedes Classe G 3 located on my engine
Check your high engine
If you discover a clicking noise on Mercedes Classe G 3, and this noise is located at the top of the engine, it means that it comes from your cylinder head and its associated parts. Two elements can be the causes of these ticking noises on Mercedes Classe G 3. 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 vanish when hot. Otherwise, it is the interplay of your rocker arms or their state of wear that is at issue. In this case, remember to change them.
Check your low engine
If you have identified the region of source of the Mercedes Classe G 3 clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both circumstances, the risk in the long term is the breakage of the motor.

Check the state 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 trigger, comes from your injection, which is either blocked or one or more injectors are destroyed.

I discover a clicking noise on Mercedes Classe G 3 in my direction
Check the state of the gimbals
One of the most common causes of a clicking noises in the direction of your Mercedes Classe G 3 is linked 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 changed rapidly, otherwise the entire cardan shaft will have to be changed. Consider taking a look at it.

Check the rest of your direction

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 Mercedes Classe G 3 coming from my suspensions
Check the suspension
If you encounter a clicking noise on your Mercedes Classe G 3 when you pass a speed bump, it is very conceivable that your suspension block is the reason 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 function and during small jolts that compress the suspensions. To check if this is the trouble that concerns you, take a dented road and, at low speed, focus on the noise coming from your front axle when ever you pass over holes. If these are the cups, consider changing them promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you notice a clicking noise on your Mercedes Classe G 3 at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a cause. To check the shape of the spring, place the vehicle 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 check 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 answer 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 consider replacing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Classe G 3 than a clicking noise, don’t hesitate to consult this article.
