There aren't 'pawls' in the new Shimano free hubs. It's a different system.intermittent skipping of Shimano freehub points to broken pawls doesn't it? It's a pretty simple swap as I recall? (though this happened so frequently to me back in the day that I decided to "invest" in a system with no pawls... haven't had any skipping issues since then, and it's been at least 10 years...)
