I posted this on the other site in response to a question, but figured it was good info to share with everyone here too.
After having 2 regulators replaced on my 2007 KJ, I asked the service manager if they could go ahead and replace the other 2 while it was there. He declined, but did tell me a hint to help keep them from breaking in the future, or at least extend the life of them. He said to make sure you regularly clean out the window tracks - especially after dust storms (here in TX) or any other dirty/sloppy weather. He also suggested spraying the window tracks from top to bottom on all 4 windows with a silicone lube spray. I have done this for a while, and it seems to help (knock on wood). If you pay attention, you can usually tell when the track is getting dirty and sticking. If the window hesitates or slows at all when raising, make sure you clean it out and re-lube it ASAP. I have caught mine a couple of times starting to stick. Then cleaned and re-lubed and it is all good again and did not break.
Just my .02. Hope it helps y'all in the future.
Make sure to clean all windows tracks out with a wet rag.

Rear: On this one, you can't fit a finger in there. Just wad up a corner of the rag and run it through the track.
Then after they have all been wiped clean, allow the excess water to dry. Then spray each of the tracks with a silicone lube spray as shown below.
, been doing it on the window tracks on my rigs for I don't know eighteen/twenty years now, just part of my regular monthly maintenance
