Hey guys, a couple of edits to my thrust arm DIY article, post #29 above. Thanks to CHIVAS for the suggestions.
Regarding the ball joint removal tool: There are a number of different styles of tools, and depending on the one you get, you'll be doing a little bit of trial and error to figure out how best to position it for maximum effect. With some of them, the fit is better if you pry the ball joint boot up and out of the way. I simply used a hammer to lightly tap the bottom of the tool into position over the boot.
It takes a lot of force from the tool to break the ball joint loose. Towards the end, I had a rag wrapped around the wrench to pad it, I was torquing so hard on the tool. Just about the time you're thinking "this is not going to work", it breaks loose. Now here's a "heads-up" - when it finally does, it's with an explosive report like a pistol shot, so be ready for it. I thought I'd broken something when I heard it the first time.
Regarding removal of the large bolts that hold the bushing side of the thrust arm to the frame: The ones on my car slid out very easily, but I've had other guys tell me that theirs took a little more work to remove, and that they had to use pliers. This may be due to water or some other fluid having seeped in and seizing the bolt.
