It is never pleasant to find out a sound in your car that you don’t know the origin of. So, what if you detect a loud noise that persists on your Ford Flex? It is highly plausible that this is a minor issue, but before beeing sure, it is better to complete some inspections. Whether that loud noise comes from the front of the car, from the rear, whether it shows up when you accelerate or when you are parked, our team has created this article to help you fix it. First, we will point out the possible reasons for the trouble according to when loud noise appears on your Ford Flex, and then we will look into the region of origin of the noise. In any case, if this noise persists, follow these advice to help you find the origin.

When does my Ford Flex produce a loud noise?
One way to discern a noise from your Ford Flex is to define when it shows up. Indeed, some problems can be related to parts that are only stressed under certain types of conditions. It is this technique that we will focus on in this first part.
Loud noise Ford Flex when accelerating
Loud noise on Ford Flex that appears when you are accelerating can be symptomatic of several 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 provoke a much higher noise than during normal process. Additionally, it is also highly plausible that loud noise on your Ford Flex is associated with a wheel bearing, which is one of the most common origins of these types of manifestations. 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 increases speed.

When my Ford Flex is stopped
If your Ford Flex 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 cause.
Where does loud noise come from on my Ford Flex and how can I be sure of its origin?
Now that we have identified the cause of the noise, we will focus on the verification stage to make certain that this is the concern you are enduring.

The loud noise comes from the wheels of my Ford Flex
As we have seen previously, loud noise from the wheels of your Ford Flex may be connected 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 as soon as possible. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Ford Flex that is the matter, you will tend to feel a vibration in the direction of the vehicle as you go faster. In both situations, you will have to go to your auto mechanic to change the tires or do a balancing.

The loud noise comes from the engine of my Ford Flex
In case you have identified loud noise as coming from the engine of your Ford Flex, 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 Ford Flex 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 disorders, take your vehicle 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 Ford Flex, 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 Ford Flex, 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 car 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.
