While breaking down my forks to replace the seals I ran into a issue that concerned me. 1st fork came apart easy but when I tried taking the bottom rebound nut off trouble followed. When compressing the fork the rebound nut would not come out of the fork leg. It seems to be retracting into the fork leg. I finally got it off and noticed the rod on the inner chamber was retracted in. I can pull it out and it retracts back in everytime. Anybody know whats happening here? I assume it's time to break the inner chamber down and refill it.
