- Raise and support the vehicle.
- With the suspension fully extended (at full travel) clamp a dial indicator to the lower control arm with the plunger indexed against the steering knuckle leg.
- Zero the dial indicator.
- Use a stout bar to pry on the top of the ball joint housing-to-lower control arm bolt with the bar tip under the steering knuckle leg.
- Measure the axial travel of the steering knuckle leg in relation to the control arm by raising and lowering the steering knuckle as in the previous step.
- If the travel is more than 0.05 in. (1.25mm), the ball joint should be replaced.
REMOVAL & INSTALLATION
The lower ball joints are permanently lubricated, operate with no free-play, and are riveted in place. The rivets must be drilled out and replaced with special bolts.
- Remove the lower control arm.
- Position the assembly with the ball joint up.
- Center punch the rivets on the ball joint housing side.
- Using a drill press with a 1 / 4 in. (6mm) bit, drill out the center of the rivet.
- Using a 1 / 2 in. (13mm) bit, drill the center of the rivet until the bit makes contact with the ball joint housing.
- Using a 3 / 8 in. (9mm) bit, drill the center of the rivet. Remove the remainder of the rivet with a punch.
- Position the new ball joint on the control arm and tighten the bolts to 60 ft. lbs. (81 Nm).
- Install the control arm and tighten the ball joint clamp bolt to 50 ft. lbs. (68 Nm); the pivot bolt to 105 ft. lbs. (142 Nm) and the strut stub to 70 ft. lbs. (95 Nm).
The ball joint housing is bolted to the lower control arm with the joint stud retained in the steering knuckle by a clamp bolt.
- Raise and support the car.
- Remove the steering knuckle-to-ball joint stud clamp bolt and separate the stud from the knuckle leg.
- Remove the 2 bolts holding the ball joint housing to the lower control arm.
- Pry the ball joint arm from the control arm.
- Remove the ball joint housing.
- Install a new ball joint housing to the control arm. Tighten the retaining bolts to 60 ft. lbs. (81 Nm).
- Install the ball joint stud in the steering knuckle. Tighten the clamp bolt to 50 ft. lbs. (68 Nm).
- Lower the car.
The ball joint is pressed into the lower control arm on these models and is retained to the steering knuckle by a clamp bolt. The lower control arm must be removed from the vehicle and placed in a press to perform this operation.
- Pry off the rubber grease seal.
- Position the receiving cup tool C-4699-2 to support the lower control arm while receiving the ball joint assembly.
- Install a 1 1 / 16 in. (27mm) deep socket over the stud and against the joint upper housing.
- Apply pressure from the press to remove the joint from the arm.
- Position the ball joint housing into the control arm cavity.
- Place the assembly in the press with the installer tool C-4699-1 supporting the lower control arm.
- Align and press the assembly until the ball joint bottoms against the control arm cavity down flange.
- With a 1 1 / 2 in. (3mm) socket, press the seal onto the ball joint housing so that it seats against the lower control arm.
