Loud Noises from under car

[Bev Smith]

Hearing Loud Noise (like a car low to the ground and tire sounds would make)
but under the car, possibly either a wheel bearing or a water pump? Is this something common at 50-60 miles per hour.

 

[OUTLAW]

does the noise vary with speed? how about left to right ? how about off and on the throttle (pinion bearing) ? is a tire low?

 

[EvilScamp]

Maybe an axle bearing?

Could be many different things. Find out if it does it coasting, rev up the engine, etc.
It needs to be narrowed down before a definitive answer can be given.
