Jack up the front of the vehicle and place it securely on jackstands, then remove the front wheels. Next, take off the nuts holding the shock absorber to the upper mount, using locking pliers on the flats at the top of the shock rod to prevent it from turning. If the vehicle has remote-controlled variable shock absorbers, loosen the two bolts securing the actuator assembly to the shock absorber stud end, then remove the upper shock absorber hold-down nut and actuator mounting bracket, followed by the lower shock absorber hold-down nut and actuator washer assembly with the stud pin, taking care not to bend the stud pin. After that, remove the upper washer and rubber cushion from the shock absorber shaft. For 2WD models, remove the two bolts securing the shock absorber to the lower arm from below, lower the shock absorber through the lower arm, and take it out of the vehicle. For 4WD models, remove the two shock absorber-to-lower
Control Arm bolts from the upper surface of the arm, fully compress the shock absorber, and lift it up and over the arm to remove it. Finally, installation follows the reverse order of removal, ensuring that the washers and bushings are assembled correctly and that all bolts and nuts are tightened securely.
