Here are the tools that we will use to change out the U-joint. You’ll need a hammer, some tongue-and-groove pliers, a couple of flat-blade screwdrivers, a file (preferably a round file), rags, a great big socket that a U-joint cap will fit inside of (we used a 11⁄8-inch), a small socket that matches the outside diameter of the U-joint cap (we used a cracked 15mm), and a new U-joint. Note the large rock to the right. That’s our anvil. You could bring along a small board or use a rigid front bumper, but you’ll probably chip the paint.
