Maybe that thumping noise is the sound of another car smashing into the rear of your car.
The cv shaft
you have a bad alternater or belt
It would depend on what part is making the loud noise. We are going to need more info.
It depends on the nature of the noise.
Drive the car on the road about 25 mph. Weave the car left and right. If the noise changes then it is the front wheel bearings.
If applicable, you may have a faulty (locked up) fan clutch.
maybe you have a muffler problem
Sounds like wheel bearings.

It is possible that a part of the EGR valve has fallen out. This will cause a very loud exhaust noise.
it should last the life of the car unless its making a seriously loud noise
