You all are right! I did not realize the ball joint was integrated with the control arm. I had assumed it was all one piece. However, after everyone's replies, I checked on Fastlane and closely examined the replacement parts and did see that they are two separate pieces. I will squirt some WD-40 on the ball joint later to be 100% positive it is the source of the noise but I'm sure that it is now. Thanks again for your helpful replies. You kept me from ordering the wrong part and saved me many $$.

How difficult are ball joints to replace? I just purchased the chassis manuals for my car but have never done this repair.
