4. Carefully pull out the strut assembly from the vehicle.
Rear Shocks:
1. Remove the rear wheel to gain access to the shock absorber.
2. Unscrew the bolts securing the shock to the lower mount and the upper mount.
3. Remove the shock from the vehicle.

4. Install New Shocks or Struts

Front Shocks/Struts:
1. Place the new strut assembly into position and secure it to the upper mount.
2. Reattach the lower bolts to the steering knuckle and resecure the brake line and sensors.
3. Torque all bolts to the manufacturer’s specifications.
Rear Shocks:
1. Position the new shock absorber into the mounting locations.
2. Secure the lower and upper bolts firmly.
3. Torque the bolts to the manufacturer’s specifications.

5. Reassemble
