I’m overhauling my Fox F125 open-bath fork, and I got the damper cartridge out and the new seals in. However, I put the damper cartridge back in and I’m having trouble. On the left side, the nut on the bottom of the fork leg screws onto the threads just fine. However, the threads on the right side are turning as I try to turn the nut. The bottom part of the damper cartridge turns independently of the top part, so the threads turn, and the nut doesn’t go on. How can I keep this part of the cartridge from turning?
