I had a hard time getting one of the bushings on also, when I did the other one I put a BUNCH of wheel bearing grease on the bearing and control arm and it slide on with a moderate amount of force. The second one went on by hand in about 2 min, no prying needed. The first one (with a small amount of grease) had to be forced on and took over 30 min. For those who are going to try this just remember to use LOTS of grease and it should be no problem, I basically filled almost the entire inside of the bushing with grease, most of it gets pushed out.
Hope that helps.
