Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect and Remove the Ball Joints

Locate the ball joint assembly on the control arm.
Remove the cotter pin (if present) from the castle nut using needle-nose pliers.
Use a socket wrench to remove the castle nut from the ball joint.
If necessary, use a ball joint separator tool to free the ball joint from the steering knuckle.

4. Install the New Ball Joints

Position the new ball joint into the control arm.
Reattach the steering knuckle to the ball joint and secure with the castle nut.
Insert a new cotter pin to secure the castle nut.

5. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (typically around 76 lb-ft for Toyota RAV4).
Reconnect the battery.
