Yes, I have the Baum tool.

I've decided to replace only the front bushings, not the rear. The front bushings are clearly shot, while the rear bushings look very good on inspection. As the front bushings appear to be 99% responsible for the problem, in my opinion it's not worth the time and cost to replace the rear. I could be wrong, but I'm willing to take the chance. I'll post later with the results.
