When reversing and steering wheel is moving a loud rattling noise comes from around the front wheel area underneath.No noises happenwhen driving forward even when steering wheel moves.

My wife is 96 will do that when backing out of our driveway. l have replaced both front wheel bearings both ball joints and tie rod ends. l think it is just the bushings that mounts the ''A-Arm to the subframe making a noise while the chassis is flexing. Nothing major those mounts are not greased so they are dry and squawk when they move.
