After researching a bit more, I found that I may have been expecting too much from my puller. It really won't pull the steering arm off, it is best used to put pressure on the connection so that when you tap the side of the steering arm it "pops" right off. This morning I went out to try this technique and one side came right off. The other side took a bit of work, but it also came off. The steering arms are in the parts washer soaking a bit.
