Always use extreme caution when working with coil springs. Make sure the vehicle is supported sufficiently.
REMOVAL & INSTALLATION
Ford recommends that if one spring requires replacement, the other spring should be replaced also.
- Raise the vehicle and support the body at the rear body crossmember.
- Lower the hoist until the rear shocks are fully suspended.
The axle must be supported by a hoist, a transmission jack, or jackstands.
- Place a transmission jack under the lower arm pivot bolt and remove the bolt and nut. Lower the transmission jack slowly until the coil spring load is relieved.
- If the vehicle is equipped with a rear stabilizer bar, remove the four retaining bolts and remove the stabilizer bar.
- Remove the coil spring and insulators from the vehicle.
- Place the upper spring insulator into the spring seat in the body. Tape in place, if necessary.
- Place the lower spring insulator on the lower arm. Install the internal damper into the spring.
- Position the coil spring on the lower arm spring seat. Slowly raise the transmission jack until the arm is in position. Insert a new rear pivot bolt and nut, with the nut facing outwards. Do not tighten the nut and bolt at this time.
- Lower the transmission jack. Raise the axle to curb height. Tighten the lower arm pivot bolt to 85 ft. lbs.
- If the vehicle is equipped with a rear stabilizer bar, install it at this time. Tighten the horizontal mount bolts to 35 ft. lbs. and the vertical mount bolts to 20 ft. lbs.
- Remove the crossmember supports and lower the vehicle.
