When does my Renualt Express make a loud noise?
One way to detect a noise from your Renualt Express is to identify when it shows up. Indeed, some complications can be linked to components that are only stressed under certain circumstances. It is this technique that we will focus on in this first part.
Loud noise Renualt Express when accelerating
Loud noise on Renualt Express that takes place when you are accelerating can be symptomatic of several failures. Indeed, if you experience 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 operation. Furthermore, it is also highly plausible that loud noise on your Renualt Express is connected to a wheel bearing, which is one of the most common origins 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 increases speed.

When my Renualt Express is stopped
If your Renualt Express 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 Renualt Express and how can I be sure of its origin?
Now that we have defined the origin of the noise, we will look into the verification step to be sure that this is the matter you are enduring.

The loud noise comes from the wheels of my Renualt Express
As we have seen before, loud noise from the wheels of your Renualt Express 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 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 straight away. 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 Renualt Express that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, 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 Renualt Express
In case you have discovered loud noise as coming from the engine of your Renualt Express, 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 Renualt Express 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 cause 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 problems, 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 Renualt Express, 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 Renualt Express, 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 automobile 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.
