Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the suspension system.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle and secure it on jack stands.
Ensure the vehicle is stable and safe before proceeding.

3. Remove the Wheel

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

4. Inspect and Replace Ball Joints

Inspection:
- Check the ball joints for play and wear using a pry bar to lift the control arm.
Replacement (if necessary):
- Remove the cotter pin from the ball joint nut using pliers.
- Use a socket to remove the ball joint nut and separate the ball joint from the control arm using a ball joint separator tool.
- Install the new ball joint by reversing the removal steps, ensuring it is torqued to manufacturer specifications (usually around 30-50 ft-lbs).
Reinstall the cotter pin and ensure it is properly secured.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the jack.
Torque the lug nuts to the manufacturer's specifications (typically around 100-150 ft-lbs).
