Relatively simply job with the right tool. Luckily I had it. Removed old door hinge retained the plastic bushings reinstalled new hinge and hung the door. It took a few attempts to get the bushings to line up, but the job went well . Took approximately 15 minutes. The self tapping screws that came with the hinge were a little too big. I used the old ones because I didn't want to stress out any material.
