When does my Lexus GX produce a loud noise?
One way to find a noise from your Lexus GX is to define when it appears. Indeed, some problems can be connected to parts that are only stressed under certain types of conditions. It is this process that we will focus on in this first part.
Loud noise Lexus GX when accelerating
Loud noise on Lexus GX that shows up when you are accelerating can be symptomatic of different failures. Indeed, if you experience a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will cause a much higher noise than during normal operation. Furthermore, it is also highly plausible that loud noise on your Lexus GX is associated with a wheel bearing, which is one of the most common origins of these types of manifestations. Another possibility is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also plausible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Lexus GX is stopped
If your Lexus GX makes a loud noise while not accelerating, engine on, the problem may be connected 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 Lexus GX and how can I be sure of its origin?
Now that we have determined the source of the noise, we will deal with the verification step to be certain that this is the issues you are encountering.

The loud noise comes from the wheels of my Lexus GX
As we have seen previously, loud noise from the wheels of your Lexus GX may be connected to two main complications. 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 change 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 Lexus GX that is the problem, 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 technician to change the tires or perform a balancing.

The loud noise comes from the engine of my Lexus GX
In case you have recognized loud noise as coming from the engine of your Lexus GX, 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 encounter a power loss during your acceleration. If the loud noise on your Lexus GX 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 noticed comes from the exhaust pipe of your Lexus GX, it is highly plausible 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 Lexus GX, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To confirm this, get help from someone who will stand under the vehicle 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.
