Changes the thermal actuator to a mechanical setup. It's on my list for both my trucks this Fall when I have some time.
This has been my plan for quite some time as well. Just haven't gotten to it yet. Thankfully, I've never had a problem with my actuator in the 14 years I've owned the Tahoe.... knock on wood... but it's bound to leave me without 4X4 one of these days.
