Like someone said, basic hand tools.
For a 2007 Ram 1500 Crew Cab w 4WAL brakes, I found a USA-made replacement hub at NAPA. $205 includes new ABS Sensor.
Offshore built are available substantially cheaper.

-Remove tire/wheel
-Remove caliper with 10mm socket, 17 mm backup wrench
-Remove brake pads
-Remove caliper bracket with 22mm socket and breaker bar
-Remove disc rotor
-Disconnect ABS sensor wire.
-Remove hub unit with 18mm socket and breaker bar
-Install new hub, torque to 120 ft-lbs.
-Re-connect ABS Sensor wire
-Re-install disc rotor
-Re-install caliper bracket, torque to 130 ft-lbs
-Re-install brake pads
-Re-install caliper, torque to 24 ft-lbs
-Re-install tire/wheel

Not only did this fix the disc rotor grinding on the caliper, the cruise control works again too.
