I removed the freehub with the TL-FH10 removal tool. Damn that freehub was tight! The old freehub spun more quietly and easily than the new one, so I wondered whether that's because the pawls were not moving easily enough, which might also explain the skipping I sometimes have. I soaked the old freehub in rubbing alcohol and now it's a little noisier when I spin it. It still spins more easily than the new one.
I now have two possible courses of action:
1) Install the old freehub and observe whether there's any skipping.
1a) If there's no skipping, conclude that soaking the freehub freed its pawls and solved the original problem.
1b) If there's skipping, conclude that the old freehub is shot and install the new freehub.
2) Install the new freehub.
The second course of action is guaranteed to give me a better ride, but it won't let me learn whether or not I've solved the problem by soaking the old freehub.
I'm going with the first option because I will learn more, and I can always install the new freehub whenever I want to.
