It is never enjoyable to notice a sound in your vehicle that you don’t know the cause of. So, what if you recognize a loud noise that is persistant on your Toyota Hilux? It is extremely plausible that this is a minor issue, but before beeing sure, it is better to do some investigations. Whether that loud noise comes from the front of the vehicle, from the rear, whether it appears when you accelerate or when you are parked, our team has made this article to help you solve it. First, we will detail the possible causes for the issue according to when loud noise appears on your Toyota Hilux, and then we will focus on the region of origin of the noise. In any case, if this noise continues, follow these instructions to help you find the source.

When does my Toyota Hilux make a loud noise?
One way to discern a noise from your Toyota Hilux is to determine when it shows up. Indeed, some problems can be linked to components that are only stressed under certain occasions. It is this approach that we will focus on in this first part.
Loud noise Toyota Hilux when accelerating
Loud noise on Toyota Hilux that starts when you are accelerating can be symptomatic of multiple failures. In fact, if you feel 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 use. In addition, it is also highly plausible that loud noise on your Toyota Hilux is related to a wheel bearing, which is one of the most common origins of these types of symptoms. 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.

When my Toyota Hilux is stopped
If your Toyota Hilux makes a loud noise while not accelerating, engine on, the issue may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the reason.
Where does loud noise come from on my Toyota Hilux and how can I be sure of its origin?
Now that we have found the source of the noise, we will focus on the verification stage to make certain that this is the matter you are experiencing.

The loud noise comes from the wheels of my Toyota Hilux
As we have seen earlier in this article, loud noise from the wheels of your Toyota Hilux may be linked 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 keep 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 change it or them right away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Toyota Hilux that is the trouble, you will tend to feel a vibration in the direction of the car as you go faster. In both cases, you will have to go to your auto mechanic to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Toyota Hilux
In case you have identified loud noise as coming from the engine of your Toyota Hilux, 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 Toyota Hilux 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 trouble, take your car to your service garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have discovered comes from the exhaust pipe of your Toyota Hilux, 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 Toyota Hilux, 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 origin 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.
