Make : FORD Model : F150 Year : 2003
Service Bulletin Num : 031703 Date of Bulletin: MAR 17, 2003
Component: STEERING:HYDRAULIC POWER ASSIST:PUMP
Summary:
WHINE NOISE FROM THE POWER STEERING PUMP MOST NOTICEABLE WHILE TURNING AT SLOW SPEEDS. *TT *JB

 

If it sounds like a clunking noise, could be a steering yoke assy but I think you would hear the noise no matter which way you turned the wheel or maybe a pitman arm which I had go bad on my 02 SCREW

 

Be cautious. I had my tie-rod break on the drivers side while I was backing out of my parking space at work only 3 days after I returned from a trip to Cape hatteras N.C.. I drove the truck at 75-80 miles an hour for 12 hours coming home, to have this happen only 3 days later. It jambed inside the wheel when it broke and actually broke the aluminum rim in half.
I have an 01 Supercrew with 69,000 miles on it. I have talked to many who have experienced this issue at 45,000 + miles.
May not be your problem, but its always better to be safe than sorry.
