Answer
Hi Larry,
The tire pressure is a good step in the right direction, but also check the tires for wear.
If the rear are more worn than the front, or vice versa, then the difference in circumferrence will generate a torque on the driveshafts and gearing that will tend to hold it engaged.
Try stopping, and changing direction when you shift from 4X to 2X. Back up a ways, and see if it disengages.
