Using this tool is easy. First, grab your 1/2' drive ratcheting socket wrench. With it, you can smoothly remove and install the transmission and differential bearing carriers. You can also use it for tasks like replacing differentials and axle seals, and setting bearing preload. Remember, this tool is not for use with an impact wrench. Using an impact wrench to rotate the bearing carriers can cause problems, so always avoid it. To keep your tool in good shape, after each use, clean it to remove any dirt or debris. Store it in a dry place to prevent rust. Since it's made from high - grade carbon steel and hand - welded, it's built to last. But following these simple steps will help it serve you well for a long time.
