Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, ball joint separator, grease gun (if re-greasing).
Park the vehicle on a flat surface and engage the parking brake.
Allow the vehicle to cool down if recently driven.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Use a lug wrench to remove the lug nuts and take off the front wheel.

4. Inspect and Remove the Ball Joint

Check the ball joint for any visible damage or excessive play.
If replacement is necessary, use the ball joint separator to detach the ball joint from the control arm.
Remove any retaining bolts or nuts holding the ball joint in place.

5. Install New Ball Joint

Position the new ball joint in place and secure it with the retaining bolts or nuts.
Torque Specifications: Follow manufacturer specifications for torque values (typically around 50-100 ft-lbs, but verify with a service manual).
If applicable, re-grease the ball joint using a grease gun.

6. Reassemble

Reattach the wheel and tighten the lug nuts in a star pattern.
Lower the vehicle from the jack stands and remove the jack.
