Changing fork internals on my Superlite means getting the front wheel off. Ran into a snag while trying to remove the axle. 14mm socket turns it from the right side, but it is turning the whole assembly with the speedo unit in the aluminum fork bottoms and then stops coming out after about 2mm. What gives? What's the trick?
The only thread on the axle is on the left side. You need to have the pinch bolts tight enough to stop the thread sleave from turning. If it still wants to turn, you may have some damaged or corroded threads.
Leave the two pinch bolts tight on the left (speedo) side and loosen the two pinch bolts on the right side of the fork. As 944SS said, it's a treaded sleeve that will turn with the axle if the pinch bolts are loose.
