I don't think that lubrication is the issue, it is the stress that the "worm" places on the plastic threaded holder that it screws into in the carrier. Look closely at the picture on the first page, and you'll notice that the aluminum window bracket is curved. Picture the window glass itself laying on top of it, as it connects to the carrier in that oval hole with a ball stud and retaining clip. As the carrier travels up and down on it, the place where the "worm" attaches to the carrier bears the weight of the window glass as it shifts forward and back on the curvature of the bracket. That will eventually seperate the cheap plastic - but then again it doesn't take much, I only raised and lowered each of my rear windows maybe 12 - 15 times in the time I've had the Jeep. In the Louisiana heat, you don't lower the windows - you use the A/C. In fact, another user suspected that the heat itself may have been the issue.
