• Install the new ball joint:
  • Press the new ball joint into the control arm using the ball joint press, ensuring it is seated properly.

5. Reassemble the Components

• Reinstall the control arm:
  • Bolt the control arm back to the chassis, using the manufacturer's torque specifications.
• Reconnect the sway bar link:
  • Reinstall the sway bar link to the control arm and tighten the nut to specification.
