Installation Instructions for Coilover Lowering Springs
- 1). Place wheel blocks in front of and behind one front wheel. Loosen the rear lug nuts by turning them counterclockwise with the lug wrench. Leave them in contact with the wheels. Place the jack under the frame in front of a rear wheel and raise the car until the rear wheel is off the ground. Repeat on the other side. Remove the wheels.
- 2). Open the trunk. Release the seat back and allow it to fold forward. Remove the screw at the bottom of the rear seat side bolster. Remove the two clips at the top and remove the side bolster.
- 3). Roll the jack under one rear control arm and raise the jack to support the control arm. Remove the two outer upper strut mount bolts by turning them counterclockwise with a wrench or socket and ratchet.
- 4). Remove the lower strut mount bolt by turning the nut counterclockwise with the ratchet and socket. Lower the jack, allowing the control arm to pivot down, allowing the upper strut assembly to come clear of the body. Remove the strut assembly from the car.
- 5). Clamp the strut securely in a vise without distorting the tube. Compress the coil spring 2 to 3-inches with the spring compressor. Remove the upper locking nut by turning it counterclockwise with a ratchet and socket. Measure the height of the coil spring. Release the spring and remove the compressor and spring.
- 6). Compress the new spring until it is the same height obtained in the measurement in the previous step. Slide the coil over the strut and install the upper cap. Replace the upper locking nut by turning it clockwise by hand, then torque it to 22 foot-pounds.
- 7). Align the upper mount studs with the holes and slide the strut into place. Lift the bottom of the strut over the lower control arm and into place. Lift the control arm by raising the jack until the lower mounting holes line up. Slide the bolt into place and thread the nut on by hand, turning it clockwise until tight. Raise the jack to load the suspension. Torque the lower mount bolt to 40 foot-pounds. Thread the upper mount bolts clockwise by hand until tight and torque to 28 foot-pounds. Lower and remove the jack.
- 8). Repeat Steps 3 through 7 on the other side of the car.
- 9). Install wheels and thread the lug nuts onto the studs. Raise the vehicle off the jack stand and lower it until the wheel contacts the ground. Torque the lug nuts to 80 foot-pounds. Lower and remove the jack. Repeat the process on the opposite side of the car. Remove the wheel blocks.
