One way to discover a noise from your Nissan Terrano is to determine when it appears. Indeed, some trouble can be connected to components that are only stressed under certain occasions. It is this process that we will focus on in this first part.
Loud noise Nissan Terrano when accelerating
Loud noise on Nissan Terrano that shows up when you are accelerating can be symptomatic of different failures. In fact, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will induce a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Nissan Terrano is in connection with a wheel bearing, which is one of the most common origins of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the issue 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 Nissan Terrano
As we have seen previously, loud noise from the wheels of your Nissan Terrano may be linked 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 remember 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 swap it or them straight 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 Nissan Terrano that is the matter, you will tend to feel a vibration in the direction of the car as you go faster. In both situations, you will have to go to your auto technician to change the tires or accomplish a balancing.

The loud noise comes from the engine of my Nissan Terrano
In case you have recognized loud noise as coming from the engine of your Nissan Terrano, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected with 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 Nissan Terrano 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 examine that the engine idle speed is not random. In case you confirm one of these two problems, take your car to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Nissan Terrano, it is highly plausible that you have rust if your car is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Nissan Terrano, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the car 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.
