I did it with the rear still on the car, using the HRPartsNStuff tool.
It went smoothly, but make sure that you stop half way and back the tool out and reposition it.(Mentioned in the directions.)
I bent the threaded rod on my tool by getting too greedy and trying to pull the second old bushing out with just one shot. (Since the first one came out so easily using the pull halfway, then reposition method.) Live and learn!!
I was able to use the tool to install the new bushings, even with the threaded rod slightly bent.
Lube up the inside of the ears with Anti-Seize and they went in like butter!
Good Luck & ENJOY !!!
