When does my Land Rover Defender produce a loud noise?
One way to identify a noise from your Land Rover Defender is to establish when it appears. Indeed, some concerns can be connected to components that are only stressed under certain circumstances. It is this technique that we will focus on in this first part.
Loud noise Land Rover Defender when accelerating
Loud noise on Land Rover Defender 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 use. In addition, it is also highly plausible that loud noise on your Land Rover Defender is connected to a wheel bearing, which is one of the most common causes of these types of symptoms. Another possibility 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.

The loud noise comes from the wheels of my Land Rover Defender
As we have seen previously, loud noise from the wheels of your Land Rover Defender may be in connection with 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 bear in mind 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 as soon as possible. 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 Defender that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your technician to change the tires or perform a balancing.

The loud noise comes from the engine of my Land Rover Defender
In case you have identified loud noise as coming from the engine of your Land Rover Defender, 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 encounter a power loss during your acceleration. If the loud noise on your Land Rover Defender 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 induce 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 disorders, take your automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Land Rover Defender, 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 Defender, 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.
