It is never pleasant to experience a sound in your automobile that you don’t know the cause of. So, what if you recognize a loud noise that lasts on your Scion xB? It is very plausible that this is a minor problem, but before beeing sure, it is better to carry out some verifications. 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 written this content to help you fix it. First, we will describe the possible reasons for the problem according to when loud noise appears on your Scion xB, and then we will give attention to the region of origin of the noise. In any case, if this noise persists, follow these advice to help you find the source.

When does my Scion xB make a loud noise?
One way to detect a noise from your Scion xB is to determine when it appears. Indeed, some complications can be linked to components that are only stressed under certain types of conditions. It is this method that we will focus on in this first part.
Loud noise Scion xB when accelerating
Loud noise on Scion xB that starts when you are accelerating can be symptomatic of different failures. In fact, if you feel 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 Scion xB is associated 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 problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.

When my Scion xB is stopped
If your Scion xB 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 induce.
Where does loud noise come from on my Scion xB and how can I be sure of its origin?
Now that we have defined the source of the noise, we will concentrate on the verification step to make certain that this is the concern you are enduring.

The loud noise comes from the wheels of my Scion xB
As we have seen earlier in this article, loud noise from the wheels of your Scion xB may be linked to two main disorders. 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 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 Scion xB that is the matter, you will tend to feel a vibration in the direction of the automobile as you go faster. In both circumstances, you will have to go to your mechanic to swap the tires or do a balancing.

The loud noise comes from the engine of my Scion xB
In case you have identified loud noise as coming from the engine of your Scion xB, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be connected with 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 Scion xB 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 trouble, take your automobile to your garage .

Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Scion xB, 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 Scion xB, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To verify this, get help from someone who will stand under the vehicle while you accelerate to find the exact area of starting point 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.
