Hey guys
I have a question. The last two times I have used 4 wheel, when I disengage it, I am hearing a whining noise from the front of the truck. It seems like it goes away after several miles, but never did this before this winter. Seems like it isn't releasing completely. Is this vacuum controlled?

I wasn't sure if it was vacuum or electric. Both times it has happened, it has been extremely cold. Just don't want to screw up transfer case.
Mechanic suggested backing about 20 feet when disengaging.
Thanks for the help gator

No, for 4wd Low, it shouldn't matter, either will work. For 4wd High, stopped in neutral.

Switching from 2WD to '4 high' can be done when stopped or while driving. If done while driving, the shift will be done when you let off the gas pedal.
Switching from '4 high' to '4 low', or vice versa, you can be either rolling at 2-3 mph AND in neutral, or completely stopped, again in neutral.
It's all explained more thoroughly in the owners manual of course.
