First, we will describe the possible explanations for the trouble according to when loud noise shows up on your Land Rover Discovery, and then we will concentrate on the region of origin of the noise.

When does my Land Rover Discovery generate a loud noise?
One way to find a noise from your Land Rover Discovery is to define when it shows up. Indeed, some concerns can be related to components that are only stressed under certain occasions. It is this method that we will focus on in this first part.
Loud noise Land Rover Discovery when accelerating
Loud noise on Land Rover Discovery that shows up when you are accelerating can be symptomatic of different failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will provoke a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Land Rover Discovery is connected to a wheel bearing, which is one of the most common origins of these types of manifestations. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the trouble may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.

When my Land Rover Discovery is stopped
If your Land Rover Discovery makes a loud noise while not accelerating, engine on, the trouble may be related to poor air intake. An air intake hose that has come loose or has a hole in it may be the induce.
Where does loud noise come from on my Land Rover Discovery and how can I be sure of its origin?
Now that we have found the cause of the sound, we will look into the verification step to be certain that this is the concern you are having.

The loud noise comes from the wheels of my Land Rover Discovery
As we have seen earlier in this article, loud noise from the wheels of your Land Rover Discovery may be related to two main problems. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So bear in mind to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case replace it or them right away. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Land Rover Discovery that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your mechanic to replace the tires or perform a balancing.

The loud noise comes from the engine of my Land Rover Discovery
In case you have recognized loud noise as coming from the engine of your Land Rover Discovery, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected to a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your Land Rover Discovery is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would generate an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two problems, take your car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have detected comes from the exhaust pipe of your Land Rover Discovery, it is highly plausible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Land Rover Discovery, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify this, get help from someone who will stand under the automobile while you accelerate to find the exact area of starting point of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
