Manual window problem
 

I have a '93 xj with manual windows, locks, etc. :icon_sad:
A couple of days ago my driver side window started skreeching like a banshee whenever I lower the window. It doesn't happen when I raise the window. One day it was fine, the next, it was like this. I seems obvious that some lube is required somewhere. Does anyone know an easy way to lube what needs to be lubed without disassembling the whole dang door?
