  • 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.
