Use a ball joint separator tool to disconnect the ball joint from the control arm.
If necessary, remove any components blocking access, such as the brake caliper or rotor.

5. Install the New Ball Joint

Position the new ball joint in the control arm.
Tighten the ball joint nut to the manufacturer's specified torque (usually around 50-70 ft-lbs).
Reinsert the cotter pin if applicable.

6. Reassemble Components

Reattach any components that were removed (brake caliper, rotor).
