The loud noise comes from the wheels of my Land Rover LR4
As we have seen previously, loud noise from the wheels of your Land Rover LR4 may be related to two main trouble. 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 consider to verify 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 swap it or them quickly. If it is a deformed tire, remember to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Land Rover LR4 that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both circumstances, you will have to go to your auto technician to replace the tires or execute a balancing.

The loud noise comes from the engine of my Land Rover LR4
In case you have recognized loud noise as coming from the engine of your Land Rover LR4, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be linked to a compression loss during the engine ramp-up phase, so you should encounter a power loss during your acceleration. If the loud noise on your Land Rover LR4 is related to air intake, the check 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 verify that the engine idle speed is not random. In case you confirm one of these two trouble, take your vehicle to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have noticed comes from the exhaust pipe of your Land Rover LR4, it is highly possible that you have rust if your vehicle 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 LR4, 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 vehicle while you accelerate to find the exact area of source 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.
