My motor was fine after being lubricated. Here is the motor after being removed from the mechanism.
1) Unplug the electrical connection, and pull it through the metal between the air inlet and the engine compartment.
2) Remove the 10 mm nut on the drive shaft, and loosen the arm.
3) Remove the 3 10 mm bolts holding the motor to the wiper mechanism. The front two bolts are easy. The rear bolt you'll have to get by alternating the open end wrench from one side to the other. I was only able to get 1/8 turn on each side. Slow, but not all that difficult. Save the bolts and star lock washers.
4) Lift out the motor. Carefully wiggle off the plastic cover.
5) Remove the 4 screws holding the driver gear cover in place. Carefully lift the cover to add a couple of dabs of grease to the worm gear. I added a couple of drops of engine oil too. Replace the cover. Be sure that the gasket seats correctly. There are a couple of plastic alignment pins. Be sure to get the ground wire under the correct screw.
6) Loosen but do not remove the two Phillips head screws holding the motor case.
7) Remove each screw and it's associated anchor, but do not allow the case to wiggle.
