As part of the ’03 front suspension redesign, Ford switched to a spring and shock combination that looks a lot like a coilover. The springs sit on a perch on the shock body and are retained by a plate that threads onto the top of the shock piston rod. You can remove this spring/shock combination as a unit by first unbolting the three nuts on the upper spring mount. . The big nut in the center holds the spring top plate to the shock body. There is tension on the spring, so don’t unbolt this yet, unless you want to shoot the shock out from under the spring.
