I recently inherited a 1/2 snap on ratchet from my grandfather that is probably close to 50 years old. I notice the gears in the head of the ratchet are really worn. When i use it gets to the particular worn spot and won't ratchet. I want the tool to work as intended but i don't want to get it swapped for a new one because it has sentimental value to me. Can i get a rebuild kit? Will they give it to me for free? Will they rebuild it? I have heard it's hard to get tools replaced or repaired by a snap on truck unless your a regular customer of theirs at a shop. Any advice or personal experiences would be great. Thanks
