How do you replace a control arm on a 1994 Mercury Topaz?

If you go to www.autozone.com , click on vehicle repair on the left, check the year, then mercury, then topaz. It will bring up repair guide for 84-94. Next click on suspension and steering, then front suspension, then lower control arm. Save this site, it's great for any repairs you have. You don't have to login, and there are detailed pics :)
