Check your high engine

Check your low engine
If you have identified the spot of source of the Mercedes Benz GLC Class clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers.

Check the condition of the gimbals
One of the most basic reasons of a clicking noises in the direction of your Mercedes Benz GLC Class is linked to 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 harm the cardan shaft very quickly and must be swapped very quickly, otherwise the entire cardan shaft will have to be swapped. Consider taking a look at it.

Check the suspension
If you experience a clicking noise on your Mercedes Benz GLC Class once you pass a speed bump, it is really conceivable that your suspension block is the reason of the noise. In fact, it may be the suspension cups, which, when they are out of date, have the rubber (silentbloc) that acts as a buffer and shock absorber for the upper part of the suspension that no longer fulfils its task and during small jolts that compress the suspensions. To examine if this is the problem that concerns 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 quickly as this may affect other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Mercedes Benz GLC Class at the suspension level, it is widely conceivable that spring wear or shock cylinder deformation may be a reason. To examine the shape 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 similar on each side (empty car for measurement). You can also examine between the front and rear, if there is a gap too significant 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, make 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.
