Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, ball joint separator tool, grease gun, safety goggles, and gloves.
Ensure the vehicle is on a flat surface and turn off the engine.
Wear safety goggles and gloves for protection.

2. Lift and Secure Vehicle

Sub-steps:
1. Use a jack to lift the front of the vehicle.
2. Place jack stands under the vehicle's frame to secure it.
3. Remove the front wheel using the appropriate socket.

3. Remove the Old Ball Joint

Sub-steps:
1. If applicable, remove the cotter pin and castle nut securing the ball joint to the steering knuckle.
2. Use a ball joint separator tool to disconnect the ball joint from the steering knuckle.
3. Remove the bolts or rivets securing the ball joint to the control arm and take out the ball joint.

4. Install New Ball Joint

Sub-steps:
1. Position the new ball joint into the control arm.
2. Secure it with the appropriate bolts or rivets, ensuring you follow the manufacturer's torque specifications (typically between 30-50 ft-lbs, but verify with service manual).
3. Reattach the ball joint to the steering knuckle and secure it with the castle nut, ensuring it is properly torqued and the cotter pin is installed.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the front wheel and hand-tighten the lug nuts.
2. Remove the jack stands and lower the vehicle back to the ground.
3. Torque the lug nuts to the manufacturer's specification (usually around 80-100 ft-lbs).

6. Final Checks

Sub-steps:
1. Grease the new ball joint using a grease gun, ensuring proper lubrication.
2. Conduct a visual inspection to confirm everything is reassembled correctly.
