Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, pry bar.
Safety Warnings: Ensure the vehicle is securely lifted with jack stands before working underneath. Always wear safety glasses.

2. Lift the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands.
Place wheel chocks behind the rear wheels to prevent movement.

3. Remove the Wheel

Using a socket set, remove the lug nuts and take off the front wheel to access the ball joint.

4. Inspect the Ball Joint

Visually inspect the ball joint for signs of wear, such as cracks or grease leakage.
Use a pry bar to check for play in the ball joint by prying under the control arm and observing for any excessive movement.

5. Replace the Ball Joint (if worn)

Remove the old ball joint:
- If the ball joint is worn, use a socket set to remove any retaining bolts or nuts.
- Use a ball joint separator tool if necessary to detach the ball joint from the control arm or steering knuckle.
Install the new ball joint:
- Align the new ball joint with the control arm or steering knuckle and press it into place if applicable.
- Secure it with the retaining bolts/nuts to the manufacturer’s specified torque settings (usually around 40-50 ft-lbs, check specific service manual).

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications (typically around 76 ft-lbs for RAV4).

7. Final Check

After reassembly, double-check the ball joint and surrounding components for any missed steps.
