My Dad and I changed my Mom's Lincoln Navigators Pads in less than 12 minutes,, including removing the tires.
It's very similar to doing the front pads on a Dodge. They Pads clip in, and the calipers are unbolted from the axle, and you can use a C-Clamp to make 'em fit back on the disc.
Our Dealer wanted $250 + Parts. We bought El Cheapo's at our Auto store, and had a little Friendly competition in our driveway (who could change 'em faster w/o screwin' up)
