Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, crowbar, torque wrench, socket set, impact wrench
Lift the vehicle using a jack and support it securely on jack stands.
Remove the front wheels with a lug wrench.

2. Remove the Ball Joint

Tools Required: Socket set, impact wrench
Disconnect the brake caliper and hang it safely to avoid stress on the brake line.
Remove the rotor.
Unbolt the ball joint from the control arm using the socket set.
Use a ball joint separator tool to disconnect it from the steering knuckle.

3. Inspect and Replace

Inspect the old ball joint for wear; if it is damaged, replace it with a new one.
If replacing, ensure the new ball joint matches OEM specifications.
Apply anti-seize lubricant to the threads of the ball joint before installation.

4. Reinstall the Ball Joint

Position the new ball joint into the control arm and connect it to the steering knuckle.
Torque the ball joint bolts to manufacturer's specifications (typically around 50-70 Nm, refer to the service manual for exact values).
Reinstall the rotor and reattach the brake caliper, ensuring all bolts are torqued to specifications.

5. Reassembly

Reinstall the front wheels and lower the vehicle.
Torque the wheel lug nuts to the specified value (usually around 100-120 Nm).
