When does my Subaru Forester generate a loud noise?
One way to discover a noise from your Subaru Forester is to identify when it appears. Indeed, some problems can be linked to components that are only stressed under certain conditions. It is this method that we will focus on in this first part.
Loud noise Subaru Forester when accelerating
Loud noise on Subaru Forester that happens when you are accelerating can be symptomatic of multiple failures. In fact, if you encounter 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 process. Additionally, it is also highly plausible that loud noise on your Subaru Forester is associated with a wheel bearing, which is one of the most common causes of these types of manifestations. Another possibility 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 Subaru Forester is stopped
If your Subaru Forester makes a loud noise while not accelerating, engine on, the issue may be connected 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 Subaru Forester and how can I be sure of its origin?
Now that we have found the source of the noise, we will deal with the verification stage to make certain that this is the issues you are enduring.

The loud noise comes from the wheels of my Subaru Forester
As we have seen earlier in this article, loud noise from the wheels of your Subaru Forester 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 change it or them as soon as possible. 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 Subaru Forester that is the trouble, you will tend to feel a vibration in the direction of the automobile as you go faster. In both situations, you will have to go to your auto mechanic to swap the tires or do a balancing.

The loud noise comes from the engine of my Subaru Forester
In case you have discovered loud noise as coming from the engine of your Subaru Forester, 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 Subaru Forester 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 generate 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 automobile to your mechanic .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have perceived comes from the exhaust pipe of your Subaru Forester, 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 Subaru Forester, 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 source 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.
