MTBob,
Thanks for the great info on the jack motors. While I have the motor off the jack,I'll go ahead and check that clutch for any damage.
As for the jack itself, I wire brushed the whole screw thread and coated it with the white grease for GD openers. I ran it in and out a few times, each time wiping off the threads because first time when I backed it out the grease looked tan (rust?). I recoated it once more and ran it in and out. It is well lubed now and I can turn the acme rod with my fingers.
I thought about repainting the inner leg, but the finish is in pretty good shape, so I just waxed it good with Johnson's paste wax.
