Thanks a bunch for the replacement process of the bushings! Yep, it sounds very simple. The repair manual described how to access the idler arm by removing the drag link which, by the way, has a lot of play and might have to be replaced. I thought I had to remove the ball joints to get at the idler arm. I wasn't sure how to remove the ball joints without a puller. BTW, does your drag link have any play while the car's on the ground? Mine does. I'm aware of the "wandering rear" syndrome but it hasn't happened to my car...yet.
Thanks again for your help,
