This problem started about a month ago. Just got back from traveling for the holidays and have to resolve this problem ASAP. Sometimes, but not always, the truck will clunk or thud hard when going from almost stopped to a complete stop. Often it's just one thunk, but sometimes it almost feels like two distinct thunks. Check out this video (sound may be helpful).
This problem happens in neutral, first, or reverse. Clutch can be pressed in or let out (when in neutral). I'm noticing it when the stop is gradual, probably most often when going down a slight decline.
