All the terms are interchangeable to the best of my knowledge. 32-300 is the correct job, sections 21-25 cover the bushings at the control arm. Section 26 is the sway bar mount bushing. Hopefully I don't have to replace that.
While checking things out the other day, I found I could grab the torsion bar at the control arm and while gently rocking the car I could "feel" the groan. Usually I only hear it when navigating speed bumps at slow speed, or once and a while after exiting the interstate and driving slow on surface streets.
Typically any front end work requires an alignment afterward, but not too sure whether or not installing new bushing at these points would.
