2002 Chevy Silverado 1500 4WD sometimes stick not disengage from 4wd back to 2wd on 2002 Chevrolet Silverado 1500

My 2002 Chevrolet Silverado 1500 extended cab V8 1/2 Ton 4WD with Floor Mounted 4wd shifter, will sometimes stick and not disengage from 4wd back to 2wd. Also makes noise.

Improper shift sequence from high to low range, see owners manual for procedure! DON'T push the lockout button, just shift the lever from 2 hi to 4 hi and back, anything else you have to be stopped, engine off!

could also need linkage adjustment
Could possibly be just needing service. Have had a few with hard shifting and sticking with minor noises and tried servicing with fresh fluid and conditioner, seemed to help. Hope that's all you need.
