- 2). Remove the sway bar end link from the lower control arm using the 3/8-inch ratchet and socket and an open-end wrench. Unbolt the ball joint on the steering knuckle using the 3/8-inch ratchet and socket, then remove the knuckle from the ball joint with the ball joint separator.
- 3). Unbolt the lower control arm from the support assembly using an open-end wrench and the 3/8-inch ratchet and socket. Pull the lower control arm out of the support assembly with a firm pull.
