I've done it just recently when I replaced my passenger door (i bought my teg with the big dent on it), I found a door with the same exact color from a dismantler and replaced it myself (saved me a couple hundred bucks). I could tell you, removing the door handle was the most challenging part of it, but it's doable with a lot of patience. The most tricky part was taking off the 2 rods shown on the pic below. Actually once you've taken off the rod that is encircled, you can pull the door handle outward a little bit and you should be able to easily work on removing the other rod. Be careful not to break that plastic lock the holds the rod, it's a little stubborn to remove it. After removing the 2 rods, you have to remove the key lock mechanism as well, then you should be able to take off the door handle and replace it with the new one.
Just follow everything from the link posted above and you should be fine. Good luck!:thumbs up
