I'd already tried this previously and to be honest, now that I've done it once I wouldn't hesitate to change the seals again, it only took about an hour and a half in total.

Bear in mind you need to clean the dust wipers and the oil seal! Gently and uniformly lift up the dust wipers and clean the area where the oil seal retaining clip is with a powerful spray like contact cleaner. Next do the oil seal with the thin plastic (I use feeler gauges). Lastly or first it does not matter slide the dust wiper up the leg and use an old worn (slightly rounded off) small flat head screw driver and insert it into the grooves in the seal and slowly turn the dust wiper round and round to scrape crud out of the delicate lips. Be very careful to no dig in and damage the seal. I wrap a cloth around the top of the lower leg to stop dirt dropping into the area above the oil seal. If need be ease the circular spring of the seal and also blast out the seal with the contact cleaner (or air line) until it is totally clean.

Pop the dust wipers back down and uniformly tap home all around the leg. Use a piece of softwood on the seal and lightly tap this with a hammer until fully seated.

No bounce the fork up and down a few times. Wipe of oil from the leg and repeat until you get no more oil residue coming past the recently disturbed seals. If the oil is pretty mucky or milky think about a fork oil change.

I've never done fork seals but I do this cleaning every few months to keep the crud from building up in the seal.
