I have a 97 F150 4X4 w/ 75,000 miles on the clock that I have owned for almost a year. Recently I started hearing a squeak coming from the front end when the steering wheel is turned. I have greased every fitting I could find and the power steering fluid is full. I went so far as to WD-40 all moving parts and bushings under the front with no success. I have noticed a couple other Fords in parking lots making the same squeak. Is this a common problem with the Ford? Is it an easy fix? Any help or ideas will be very much appreciated. Thanks.
