Verify your high engine
If you listen to a clicking noise on Mercedes Classe Glc, and this noise is based at the top of the engine, it means that it originates from your cylinder head and its accompanying parts. Two parts can be the triggers of these ticking noises on Mercedes Classe Glc. Either the hydraulic pushers , in most cases it is because of their faulty “hydraulic catch-up” system that we will notice 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 case, remember to change them.
Verify your low engine
If you have determined the spot of origin of the Mercedes Classe Glc clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. 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 recommend you to replace the engine of your Mercedes Classe Glc.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Classe Glc is in connection with the combustion of your engine, there are three possible reasons of it. Verify the condition 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 trigger, comes from your injection, which is either blocked or one or more injectors are damaged. In this case, do not hesitate to read this article which deals in detail with the different injection sounds on Mercedes Classe Glc.

Verify the condition of the gimbals
One of the most common causes of a clicking noises in the direction of your Mercedes Classe Glc is connected 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 make a ticking type of sound when you approach the stop zone of your steering. A bellows with holes will damage the cardan shaft very quickly and must be swapped in a short time, 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 Mercedes Classe Glc, do not hesitate to consult this complete guide.
Verify the rest of your direction
Finally, when you detect a clicking noise on your Mercedes Classe Glc, 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 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.

Verify the suspension
If you experience a clicking noise on your Mercedes Classe Glc once you pass a speed bump, it is very possible that your suspension block is the cause 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 task and during small jolts that compress the suspensions. To verify if this is the trouble 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 promptly as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Mercedes Classe Glc at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a reason. To verify the condition 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 significant it means that most likely your springs are worn, if you discover 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 changing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Classe Glc than a clicking noise, don’t hesitate to consult this article.
