Does it not come out using the inner leg as a slide hammer, the bushes inside pushing it out?
Yep, getting them out is simple. A plastic bag to get the new seals over the fork leg and a piece or drainpipe to use as a seal driver are the only specialist "tools" needed to refit them.
It's a messy but easy job.
Yup, left fork was simple, 2 min job to get the seal out. Other one won't budge.
