Forks leaking oil

You may resort to actually having to "Rip them out"
Taking them out in chunks because the Seal is stuck to its seat in the tube.

If this is the case, you can make a tool that helps by grinding a blade-end on a big nail and tapping the nail down in between the outside of the seal and the seat of the tube.

If you do it that way ... put some heat shrink on the shank of the nail and a protective layer of Duct Tape around the top of the tube to prevent sctatching and marring while you pry-out the old seal.

It helps keep the damage to a minimum.

 

I have found it's tough to get enough snap with fork tubes mounted in the bike. For me, it was earier to mount the fork horizontally in a vise, clamping the caliper mounting points in the vise, and pulling horizintally. My first attempt I neglected to remove the damper rod retaining bolt that's recessed in the bottom end of the fork. It was a lot easier after discovering that bolt. Next time's a cake walk.
