Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, ball joint separator, grease gun.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the battery to avoid any electrical issues while working.

2. Remove Wheel

Loosen the lug nuts of the wheel you are working on.
Remove the wheel and set it aside.

3. Remove Ball Joint

Remove the cotter pin and nut from the ball joint.
Use a ball joint separator to disconnect the ball joint from the control arm.
If necessary, remove any components obstructing access to the ball joint, such as brake lines or dust shields.

4. Install New Ball Joint

Clean the area where the new ball joint will be installed.
Position the new ball joint into the control arm and secure it with the appropriate nut.
Torque the nut to the manufacturer's specifications (typically around 50-70 ft-lbs, but verify for your specific RAV4 model).

5. Reassemble

Reinstall any components that were removed for access.
Reattach the wheel and tighten the lug nuts in a criss-cross pattern to the manufacturer's specification.
Lower the vehicle back to the ground.

6. Lubricate

Use a grease gun to apply grease to the new ball joint through the grease fitting.
