You will need to remove the tire and wheel from your 2005 Dodge Durango. Remove the brake pad Springs and calipers. Tap the rotors with a hammer to loosen them. Slide the rotors off. Reverse the process to install the new rotors and brake pads.

Rotors on the front drums on the rear.
Remove caliper, pull rotor off hub, push new one on.
Rotors are easy. I am assumong that you have disc brakes... so you have to remove the calipur and the rotor will slide straight at you. If it is seized then I always do the redneck thig by tapping the center with a hammer to break it free, and/or around the edges. When you are putting the new one on don't forget to use never seize on the inside of ithe rotor to prevent it from seixing up again.
Any local brake shop will be able to turn the rotors for you Dodge Ram 1500. Depending on what is located near you Midas, Sears, and Tires Plus are all places that will turn a set of rotors.
take it to a qualified dodge mechanic
