Being subject to repeated noise on your car tends to be frustrating, a car is so complex that it is usually difficult to situate its origin and even more so to find the part that causes it. If you have already experienced a clicking noise on your Land Rover Discovery, we will probably be able to help you. Indeed, our editorial staff decided to create this article in order to review the main causes of a clicking noise on Land Rover Discovery. This is why, firstly, we will see what are the reasons 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 Land Rover Discovery coming from your suspensions.
I listen to a clicking noise on Land Rover Discovery on my engine
Verify your high engine
If you listen to a clicking noise on Land Rover Discovery, and this noise is located at the top of the engine, it means that it originates from your cylinder head and its associated parts. Two parts can be the causes of these ticking noises on Land Rover Discovery. Either the hydraulic pushers , generally it is because of their faulty “hydraulic catch-up” system that we will find out these clicking noises, often 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 case, remember to change them.
Verify your low engine
If you have determined the area of origin of the Land Rover Discovery clikcing noises coming from your low engine, it may be that your rods or piston shafts are the causes. In both situations, the risk in the long term is the breakage of the motor. These two fixes are very difficult and most mechanics will advise you to replace the engine of your Land Rover Discovery.
Combustion problem
Finally, if you have the feeling that this clicking noise on Land Rover Discovery is related to the combustion of your engine, there are three possible reasons of it. Verify the state 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 components to promote good combustion. And finally, the most classic reason, comes from your injection, which is either blocked or one or more injectors are injured. In this circumstance, do not hesitate to consult this article which deals in detail with the different injection sounds on Land Rover Discovery.
I listen to a clicking noise on Land Rover Discovery in my direction
Verify the state of the gimbals
One of the most common reasons of a clicking noises in the direction of your Land Rover Discovery 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 create 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 very quickly, 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 Land Rover Discovery, do not hesitate to read this complete guide.
Verify the rest of your direction
Finally, when you experience a clicking noise on your Land Rover Discovery, 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.
I listen to a clicking noise on Land Rover Discovery coming from my suspensions
Verify the suspension
If you encounter a clicking noise on your Land Rover Discovery once you pass a speed bump, it is extremely plausible that your suspension block is the induce 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 examine if this is the trouble that concerns you, take a dented road and, at low speed, pay attention to the noise originating from your front axle when you pass over holes. If these are the cups, consider changing them soon as this may damage other parts and require more expensive repairs.
Check spring and cylinder
If you hear a clicking noise on your Land Rover Discovery at the suspension level, it is widely plausible that spring wear or shock cylinder deformation may be a cause. To examine the state of the spring, place the automobile 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 examine between the front and rear, if there is a gap too significant it means that most likely your springs are worn, if you see a leak go a little further in the article to have the solution 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 think about swapping it or them. If you have the feeling that this noise is more like a squeaking noise on Land Rover Discovery than a clicking noise, don’t hesitate to consult this article.
