Being subject to frequent noise on your vehicle tends to be disturbing, a vehicle is so complex that it is usually 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 Mercedes Benz GLK, we will probably be able to support you. Indeed, our editorial staff decided to write this content page in order to review the main causes of a clicking noise on Mercedes Benz GLK. 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 Mercedes Benz GLK coming from your suspensions.
I hear a clicking noise on Mercedes Benz GLK on my engine
Check your high engine
If you hear a clicking noise on Mercedes Benz GLK, 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 Benz GLK. Either the hydraulic pushers , in most cases 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 condition of wear that is at issue. In this situation, remember to change them.
Check your low engine
If you have distinguished the zone of source of the Mercedes Benz GLK 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. These two repairs are very difficult and most mechanics will suggest you to replace the engine of your Mercedes Benz GLK.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercedes Benz GLK is in connection with 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 plausible 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 destroyed. In this circumstance, do not hesitate to consult this content page which deals in detail with the different injection sounds on Mercedes Benz GLK.

Check the condition of the gimbals
One of the most common causes of a clicking noises in the direction of your Mercedes Benz GLK 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 create 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 replaced in a short time, otherwise the entire cardan shaft will have to be replaced. Consider taking a look at it.

Check the rest of your direction
Finally, when you find out a clicking noise on your Mercedes Benz GLK, 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 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 Benz GLK once you pass a speed bump, it is very plausible that your suspension block is the reason of the noise. Indeed, it may be the suspension cups, which, when they are out of date, 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 worries you, take a dented road and, at low speed, focus on the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them as soon as possible as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Mercedes Benz GLK at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a cause. To check the state of the spring, position the vehicle 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 check between the front and rear, if there is a gap too large it denotes that most likely your springs are worn, if you see 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 changing it or them. If you have the feeling that this noise is more like a squeaking noise on Mercedes Benz GLK than a clicking noise, don’t hesitate to consult this article.
