I use Poly Liquid Grease on everything, door hinges, hood hinges, and yes window lifts. It sprays on like heavy WD40, then firms up into a red grease. It penetrates into the part, then acts as a grease-lasts quite a while.

Another thing about windows-if you use silicone grease on the window channels, it will greatly ease the motors chore.

And see to it that there is no "cocking" of the window as it transitions from down to up, etc. The Drivers door gets the most wear. If there is cocking, you might be able to use the mechanisms from the left rear door-perhaps they are the same, I don't know. There would hardly be any wear on that window lift.
