rear end noise - gf's car - help

hey guys

g/f drives a 94 taurs (please no brake jokes) and its making a very loud vibrating type noise at 100 plus.

sometimes the noise can be heard at lower speeds going over bumps?

any suggestions?

Bad wheel bearings maybe?

that was my first instince, but it sounds too loud to be that

loose exhaust
loose int. pannel
shattered brake pad

these would only come into play at sertan speeds and are annoying as shit
