Thank you Chris,

I'll follow your advice and compress springs.....but I'm not clear on how to remove the arms. After compressing spring and releasing bottom of shock, will I have to drop the subframe by undoing the subframe bushing connections and then the four bolts above the differential? I don't see how to get at the outside trailing arm bolts otherwise.

I used a "c" clamp to press in bushings on front suspension after applying sly-glide. That worked fine. Your home made tool idea is creative and I'll go that route if I can't get the clamps to work.
