When does my Toyota Highlander generate a loud noise?
One way to identify a noise from your Toyota Highlander is to establish when it occurs. Indeed, some concerns can be connected to parts that are only stressed under certain circumstances. It is this approach that we will focus on in this first part.
Loud noise Toyota Highlander when accelerating
Loud noise on Toyota Highlander that appears when you are accelerating can be symptomatic of different failures. Indeed, if you feel 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 use. In addition, it is also highly plausible that loud noise on your Toyota Highlander is in connection with a wheel bearing, which is one of the most common origins of these types of signs of illness. 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.

When my Toyota Highlander is stopped

The loud noise comes from the wheels of my Toyota Highlander
As we have seen previously, loud noise from the wheels of your Toyota Highlander may be connected 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 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 replace it or them quickly. 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 Highlander that is the matter, 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 technician to swap the tires or accomplish a balancing.

The loud noise comes from the engine of my Toyota Highlander
In case you have recognized loud noise as coming from the engine of your Toyota Highlander, 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 Highlander 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 cause 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 car to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have found comes from the exhaust pipe of your Toyota Highlander, 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 Toyota Highlander, 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 automobile 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.
