Raise and support the car and then unplug the tie rod end from the steering knuckle before you service or repair the lower control arm. Take out the disc brake caliper and rotor from the steering knuckle, next unhook the tension strut from the lower suspension arm and remove the shock absorber. After that, open the cotter pin and separate the steering knuckle's nut by hand and then use the Ball Joint Remover C-3564-A to tighten around the outer portion of the lower ball joint on the section. Gently press down on the lower ball joint and forcefully hit the steering knuckle with a hammer, so that the bolt comes out. Remove the spring, turn the lower suspension arm downwards and remove the coil spring and isolator pad from the car. Disconnect the bolt on the lower suspension arm pivot bolt from the crossmember, then remove the lower suspension arm itself from the vehicle. While you install, place the suspension arm on the lower crossmember, insert the spring and attach the lower ball joint to the steering knuckle. While having the retaining nut on the lower ball joint and with the vehicle level, tighten it to 183 Nm (135 ft. lbs.) for LD 11/16 bolt or 237 Nm (175 ft. lbs.) for HD 3/4 bolt, then install new cotter pins. Add the tension strut to the car, release the spring compressor and fit the shock absorber. After locking the breaker, next install the disc brake caliper, then put on the wheel and tire and bring the car down. Once you've tightened the lower suspension arm pivot bolt to 237 Nm, check the wheel alignment.
