Before anything else, raise the vehicle and support it; then take off the front wheel and tire and the disc brake caliper and rotor. Following this, separate the brake hose bracket at the upper control arm and take out the wheel speed sensor. The remove the nut and cotter pin from the upper ball joint after you have supported the lower suspension arm. Make the lower ball joint move by using Ball Joint Remover C-3564-A and then hit the steering knuckle with a hammer to trim the ball joint out of the socket. Remove the ball joint on top from the steering knuckle and loosen the pivot bar nuts to take away the suspension arm. When installing, place the suspension arm pivot bar on the frame and tighten its bolts to 298 Nm (200 ft. lbs.). Connect the steering knuckle to the upper ball joint and tighten the upper ball joint nut to 183 Nm (135 ft. lbs.). After that, insert a new cotter pin. Place the brake hose bracket and wheel speed sensor before finally putting on the disc brake caliper at the upper control arm. Remove the support beneath the bottom of the suspension arm, attach the wheel and tire and then let the car down. After everything is tested, make sure the front end complies with specifications.
