When I Go From Park To Reverse Or Drive And When I Brake To A Complete Stop, I Hear A Hollow Rubbing Noise From The Rear. When I First Took It To The Dealership, They Did Not Know What It Was Off The Bat. I Have A 2004 F-150 Supercrew, With A 6 Inch Suspension Lift. I've Been Hearing That Noise Before I Got The Lift.
