Just adding to the consensus, your 'issue' isn't and normal. Some trucks worse than others but they all do or can bind up to a degree. Your method to relieve the tension SOP.
Mine is manual Xfer case and hubs, usually just driving off the blocks enough to release the tension, if not rolling a few feet or pulling back forward.
Using 4WD to climb blocks a lot more effective- climbs instead of front tires pushing, Low range just slower more control. Just easier on the truck.
Im of the opinion 4WD should be exercised.
Curious about the lubing of front drive shaft with every oil change, are the Dodges front axles engaged full time?
