Just recently did my front mains as well. I highly reccomend this Lisle seal puller tool to help remove the shaft seals without gouging the mating surfaces: More Information for LISLE 58430
I was also a bit worried about not driving the seals in totally true and having leaks once reassembled, so I ordered a shaft seal driver kit which worked perfectly. But others have used just a socket and a block of wood although you may need to modify a socket to fit around the crank. Thefe are a few options but the one I ordered was from Alibaba.

Good luck man, you got this!
