Should I Preemptively Change Window Regulators?

[ChiefRider]

My '04 with 200k miles is on all but one of its original window regulators. Last year, the right rear door glass dropped to bottom and required a new regulator assembly.


I am expecting to arrive at the airport, etc. for long term parking only to lose a window and be screwed. What sayeth the board? Do I replace all the remaining regulators (and door handle carriers) or do I replace the various plastic clips and lubricate the existing regulators?


If I replace, what brand is currently reputable?


Anyway, thanks for the consult!
