Got a little more work done last night. Unfortunately I can only work ~1 hour during the weeknights with my current schedule so progress is slow. Got the rack/pinion completely diassembled:
Followed TTT's how-to thread and cut off the seal on the rack, and removed the bearing to get to the snap ring holding the seals on the pinion. I also pulled the spring out of the seal on the rack support.
There's still a seal (or two?) inside the rack housing that I need to figure out how to remove so I can pull their springs as well. Next step: weld up the pinion to remove the "slop:"
