In the parking lot of the tool store, I started to load the Craftsman mechanic's tool set into the back of my truck. Ironically, the handle broke and the tailgate wouldn't open. Ha.
So the first fix I got to do with my brand new tools was to replace the tailgate handle. I used a Doorman brand from the local AutoZone.
I wasn't sure how to get the handle off or get into the assembly so I Googled and found the step by step how to video below. It's great and shows you exactly what to do, step by step. In comments, some suggested not using the WD40 that he uses but a real "grease" instead. Just a tip I picked up. Take a look at the video below and the photos from my repair.
