Installed this on the back of my 2004 Nissan Titan in less than an hour. Simply pull the wheels off, remove the caliper, and then remove the old brake disc. There are no screws holding the rotor. If it doesn't come off easily, take a large hammer and hit the old rotor right next to the wheel studs. But don't hit the studs! After installation, the truck stops very quickly, the brake pedal is firm, there are no jerks.
