So my truck has been making a goofy rattling noise whenever I have the clutch in and I give it some gas, so I brought it in to the shop this morning to have them take a look at it. They said it's probably the clutch release bearing ($300) but as long as they're doing the 5 hours of labor to get at it, I might consider replacing the entire clutch ($800) which, to the best of my knowledge, has never been done to this truck. So that's sort of a bummer, but I knew that it was coming; the clutch has always been a little iffy on this thing.
