How do I replace the right side lower control.

Standard or automatic? 4 cylinder or 6?

Here are a couple of clips from a 1.8L Standard:

This one focuses on wheel bearing, but it shows the ball joint being loosened:

It might be esier if you remove the 3 bolts that secure the ball joint to the control arm and leave the ball joint attached to the
steering knuckle.

You will need to loosen either the inner CV bolts or the outer nut, so that the strut and steering knuckle can swing out so that the
control arm can swing down.

Make sure to lift and support the vehicle correctly / safely!!!!
