It is never enjoyable to experience a noise in your car that you don’t know the source of. So, what if you find a loud noise that persists on your Toyota Corolla? It is highly plausible that this is a minor problem, but before beeing sure, it is better to accomplish some investigations. Whether that loud noise comes from the front of the car, from the rear, whether it appears when you accelerate or when you are parked, our team has created this content to help you solve it. First, we will point out the possible reasons for the trouble according to when loud noise shows up on your Toyota Corolla, 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 Corolla make a loud noise?
One way to identify a noise from your Toyota Corolla is to identify when it appears. Indeed, some trouble can be linked to components that are only stressed under certain occasions. It is this technique that we will focus on in this first part.
Loud noise Toyota Corolla when accelerating
Loud noise on Toyota Corolla that appears when you are accelerating can be symptomatic of several failures. Indeed, if you experience 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 process. Moreover, it is also highly plausible that loud noise on your Toyota Corolla is related to 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 problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it gains speed.
When my Toyota Corolla is stopped
If your Toyota Corolla makes a loud noise while not accelerating, engine on, the problem may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the cause.
Where does loud noise come from on my Toyota Corolla and how can I be sure of its origin?
Now that we have defined the origin of the sound, we will focus on the verification stage to make certain that this is the issues you are enduring.
The loud noise comes from the wheels of my Toyota Corolla
As we have seen before, loud noise from the wheels of your Toyota Corolla may be linked 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 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 right away. 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 Toyota Corolla that is the issue, 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 auto mechanic to replace the tires or execute a balancing.
The loud noise comes from the engine of my Toyota Corolla
In case you have identified loud noise as coming from the engine of your Toyota Corolla, 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 Corolla 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 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 problems, take your car to your 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 Corolla, 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 Toyota Corolla, 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 car 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.
