Use a ball joint separator to detach the ball joint from the control arm.
If necessary, remove any bolts securing the ball joint to the steering knuckle.

4. Inspect and Replace

Inspect the ball joint for wear; replace if there is play or damage.
Install the new ball joint by reversing the removal steps; ensure it is seated properly.
Torque the ball joint nut to manufacturer specifications (usually around 50-70 ft-lbs).
