Ford F1LY-5310-B Front Spring

Loosen the wheel lug nuts, raise the rear of the vehicle, support it securely on jackstands placed under the frame, and remove the wheel while blocking the front wheels. Remove the rear stabilizer bar if equipped, support the rear axle assembly with a jackstand placed under the axle tube, and position a safety chain through one of the spring coils and around a convenient frame member. Use a floor jack under the lower suspension arm axle pivot bolt, remove the nut and bolt, and slowly lower the jack until the spring is fully extended. Remove the safety chain, coil spring, and insulators from between the suspension arm and the spring upper seat.

The installation involves placing the spring in the upper seat, reattaching the stabilizer bar link, and tightening pivot bolt nuts to specified torque.
