It is never relaxing to hear a sound in your car that you don’t know the starting point of. So, what if you recognize a loud noise that persists on your Toyota RAV4? It is extremely plausible that this is a minor issue, but before beeing sure, it is better to accomplish some inspections. 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 explanations for the trouble according to when loud noise appears on your Toyota RAV4, and then we will concentrate on the region of origin of the noise. In any case, if this noise remains, follow these suggestions to help you find the origin.
When does my Toyota RAV4 generate a loud noise?
One way to discern a noise from your Toyota RAV4 is to determine when it appears. Indeed, some concerns can be related to parts that are only stressed under certain conditions. It is this technique that we will focus on in this first part.
Loud noise Toyota RAV4 when accelerating
Loud noise on Toyota RAV4 that shows up when you are accelerating can be symptomatic of multiple 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 generate a much higher noise than during normal use. In addition, it is also highly plausible that loud noise on your Toyota RAV4 is related to a wheel bearing, which is one of the most common causes 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 RAV4 is stopped
If your Toyota RAV4 makes a loud noise while not accelerating, engine on, the issue may be in connection with 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 RAV4 and how can I be sure of its origin?
Now that we have located the origin of the sound, we will concentrate on the verification step to be certain that this is the issues you are experiencing.
The loud noise comes from the wheels of my Toyota RAV4
As we have seen earlier in this article, loud noise from the wheels of your Toyota RAV4 may be in connection with 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 keep in mind 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 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 RAV4 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 technician to change the tires or accomplish a balancing.
The loud noise comes from the engine of my Toyota RAV4
In case you have recognized loud noise as coming from the engine of your Toyota RAV4, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected to 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 Toyota RAV4 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 examine 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 detected comes from the exhaust pipe of your Toyota RAV4, 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 RAV4, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To validate 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.
