Power steering leak

I had to replace that same seal on a B body once. The hardest part is pulling the column out. I drove a very small flat screwdriver between the outer edge of the seal, and the seat, and pryed it right out. Taped up the splines on the input shaft to keep from boogering up the new seal, cleaned the shaft, and tapped the new seal in place with a similar sized deep well socket. Then....worked my *** of getting the column back in and lined up by myself....lol. Good luck to you!
