Ford F5VY-5560-A Spring

Start by loosening the wheel lug nuts, raising the rear of the vehicle, and supporting it securely on jackstands under the frame. Remove the rear wheels and block the front wheels. Next, remove the rear stabilizer bar and support the rear axle assembly with a jack placed under the axle housing. Use a safety chain through the spring and around a frame member for added security. Disconnect the lower studs of the two rear shock absorbers from their mounting brackets on the axle tube, and detach the height sensor connector link from the upper control arm. On 1998 and later models, disconnect the lateral arms that are part of the Watts linkage at the chassis ends. Slowly lower the jack until the spring is fully extended, and then remove the safety chain, coil spring, and insulators from between the suspension arm and the spring upper seat.
