Chris,
There are two screws that hold the motor to the firewall. There is a little rubber grommet on the rotating arm which reduces/eliminates any vibration noise from the unit. Just pull the rubber hoses, unhook the wiper control cable, remove the two screws and you are good.
If the rubber grommet is wrecked do not worry, I put the finger of a rubber glove in there, no noise yet.
