I havn't done the rear oil seal, yet, but the bushings weren't too bad. On the rear I dropped the entire spring, which made punching the forward bushings out easy. While I was at it I replaced my ubots (they were worn from being loose). The front was a little more challenging, but with the right tools, air tools that is, it was dooable (is that a word?). Using the 5" bolts to release the main spring was a must, saw that in the Haynes manual.
I should have most of it, minus the wheels and tires, done by this weekend.
Come to think of it, I will be doing the rear seals this weekend when I replace the bearings. I'll let you know how it goes.
