Being subject to recurring noise on your car tends to be frustrating, a car is so sophisticated that it is generally difficult to determine its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your Mercury Mariner, we will almost certainly be able to help you. Indeed, our editorial staff decided to write this article in order to review the main causes of a clicking noise on Mercury Mariner. This is why, firstly, we will look at what are the origins of this type of noise coming from your engine block, then those of a noise coming from your direction and finally, the origins of clicking noise on Mercury Mariner coming from your suspensions.
I find out a clicking noise on Mercury Mariner from my engine
Examine your high engine
If you find out a clicking noise on Mercury Mariner, and this sound is based at the top of the engine, it means that it comes from your cylinder head and its accompanying parts. Two elements can be the triggers of these ticking noises on Mercury Mariner. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will perceive 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.
Examine your low engine
If you have identified the region of origin of the Mercury Mariner clikcing noises coming from your low engine, it may be that your rods or piston shafts are the triggers. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very complicated and most mechanics will recommend you to replace the engine of your Mercury Mariner.
Combustion problem
Finally, if you have the feeling that this clicking noise on Mercury Mariner is linked to the combustion of your engine, there are three possible triggers of it. Examine 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 parts to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are damaged. In this circumstance, do not hesitate to read this article which deals in detail with the different injection sounds on Mercury Mariner.
I find out a clicking noise on Mercury Mariner in my direction
Examine the condition of the gimbals
One of the most basic causes of a clicking noises in the direction of your Mercury Mariner is connected 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 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 Mercury Mariner, do not hesitate to read this complete guide.
Examine the rest of your direction
Finally, when you find out a clicking noise on your Mercury Mariner, 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.
I find out a clicking noise on Mercury Mariner coming from my suspensions
Examine the suspension
If you encounter a clicking noise on your Mercury Mariner once you pass a speed bump, it is extremely possible that your suspension block is the reason of the sound. 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 concerns you, take a dented road and, at low speed, focus on 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 hear a clicking noise on your Mercury Mariner at the suspension level, it is widely possible that spring wear or shock cylinder deformation may be a explanation. 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 denotes that most likely your springs are worn, if you observe a leak go a little further in the article to have the solution 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 swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Mercury Mariner than a clicking noise, don’t hesitate to consult this article.
