To start with, lift up the front of the car and prop it on jackstands. After that, remove the wheel. Then remove the bolt holding the ball joint to the brake caliper bracket. Use a t-in drill bit to drill about ¾-in deep into the center of the rivets holding down the ball joint on the lower control arm. Drill just deep enough with a ½-in drill bit to remove rivet heads. Drive out any remaining rivets and take away the ball joint. When installing back a new balljoint in place of rivets on lower control arm, use correct size bolts and nuts on them instead. Mounting back of balljoint onto steering knuckle must be done with tightening bolt and nut by proper torque specs in order to prevent loss of control while driving. Finally mount-wheel and lower-car to ground.

All 1975 and later vehicles feature visual wear indicators on the lower ball joints, with the grease plus screws inserted into the wear indicator that extends from the bottom of the ball joint housing. If the wear indicator is visible, the ball joint is in good condition; if it is parallel with or recessed into the housing, the ball joint is defective. For 1986-87 vehicles, a special ball joint installer tool is required. Begin by raising the front of the vehicle and supporting it on jackstands, then remove the wheel. Disconnect and remove the shock absorber, followed by the front stabilizer rod link and the brake reaction rod from the lower control arm. For safety and leverage, place a jack about 1/2 inch below the lower ball joint stud. Remove the ball stud cotter pin and loosen the nut slightly without removing it. Use a tool or tap the steering knuckle to separate the stud from the knuckle. Once separated, raise the jack against the control arm, remove the nut, and detach the steering knuckle from the tapered stud. Use a ball joint remover to extract the ball joint from the lower control arm. To install, reverse the process, tightening the castellated nut to 85-90 ft. lbs. for 1975-85 vehicles, ensuring alignment with the cotter pin hole. For 1986-87 vehicles, position the ball joint stud in the steering knuckle, install the tool, and tighten the operating nut to 40 ft. lbs., then remove the tool and tighten the nut to 81 ft. lbs., again ensuring proper alignment for the cotter pin.

Remove the cotter pin from the upper ball joint stud, loosen the nut without removing it, and use a ball joint removal tool to press the ball joint downward until the tapered portion is free from the steering knuckle. Wire the knuckle and associated parts in place to protect the brake hose, then remove the nut from the ball stud along with any washers.

Raise the front end of the vehicle and remove the ball stud cotter pin, loosening the ball stud nut by one turn.

Measure the length of exposed thread on each tie-rod end for reassembly, release the pinch bolts from the clamps, and unscrew the tie-rod end from the tie-rod sleeve.
