I wrenched on replacing power window gears in the gearbox that hangs on the end of the drive motors in a 1990 Ford Pickup w/ power windows. Ford - in it's 90's wisdom made the main drive gear out of Nylon!!! Made to Crash!
You must have window glass up, speakers out, and all door panels off, then drill a 1/2 hole and dremel out two others to get to the three 8mm bolts that hold motor and drive to window regulator. Nice engineering!Then you get it loose, pull it thru speaker hole, clean-out ton of broken olastic in ancient grease from gear box and replace all gears and grease. Then stand on head to get it all into place, only dropping bolts a dozen times down into door bottom. (magnetic pick-up stick will save you there!) Then you put all the plastic covers and crap back together and hope it works.
They are FIXED! I don't know what it would have cost to have a shop do this and it is on an old truck that is just used as a fram truck, but Holy Crap - it is really hard to do!
Thanks Ford!
There went my whole yesterday...

Did this very repair to my 1986 TC two years ago. Nylon pieces (3 per motor) $4.29 delivered to my door. PITA of doing the job, just as you describe...PRICELESS!
Ford used these nylon parts to save the pot metal gearing they used in the event of a frozen window, as they allow for some cushion from the worm gear on the moter to the toothed gear that drives the window rack.
Hey... on the bright side, they worked well for 20+ years.
