So I've read all the tm and not much I can find about this problem under no load front drive shaft spins drives the front wheels .Today I wanted to make sure the front axle was engaging this is what is noted as you load up the drive line the front drive shaft starts to turn moves about a half an inch then slips back wheels are spinning in the back when I shift you can hear the air for the sprag as I believe it should I've tried it in high range and low range back off and start moving again the front drive line starts to load up moves about half an inch then slips the wheel does the same . Any ideas. There are no obnoxious noises .no grinding nothing
