A loud sound coming from the rear end of a vehicle could be caused by issues with the exhaust system, such as a loose or damaged muffler or exhaust pipe. It could also be due to problems with the suspension, such as worn-out shocks or struts. It's best to have a mechanic inspect the vehicle to determine the exact cause of the noise.
This could be caused by something loose in the duct, or a worn or broken plastic part, etc.
A roaring sound when power is applied to the rear axle could be caused by several issues, such as worn or damaged wheel bearings, which can produce a loud noise as they fail under load. Additionally, problems with the differential, such as worn gears or insufficient lubrication, may also lead to a roaring sound. Another potential cause could be tire issues, such as uneven wear or incorrect inflation, which can create noise when torque is applied. It's important to diagnose the specific source of the sound to address the issue appropriately.
