4 wheel drive acting up in reverse?
Put my 97 expedition xlt 5.4 with 4 wheel drive on
jack stands to run a test to find cause of a
vibration. In doing so, I put it in 4L and slipped it
into reverse. Rear driver side "clunk clunk clunk"
and stop and go at idle speed. Doesnt do this in 2
wheel drive. Any ideas?
