What is the rubbing noise when i turn eather way on my 2003 eddie bauer expedition?

ERIC HI I HAD THIS PROBLEM WITH MINE THE REAR END IS A LIMITED SLIP AND BINDS WHEN MAKEING TURNS AS IF IT WAS A TRUE POSI TRACTION REAR CAUSING THE GRINDING OR RUBBING NOISE YOU ARE HEARING I COULD FEEL IT IN MINE IT WAS SO BAD IT ONLY DONE IT WHEN STARING OUT TURNING OR GOING SLOW AROUND SHARP TURNS. TAKE IT TO YOUR LOCAL LUBE SHOP AND HAVE THE OIL CHANGED IN YOUR REAR END AND TELL THEM TO PUT IN THE ADATIVE RECOMENDED FOR THIS REAR END THIS SHOULD TAKE CARE OF YOUR PROBLEM MINE IS TOTALY GONE HOPE THIS HELPS
