It could be the shift motor. Also are you putting it in neutral and putting your foot on the brake when you're shifting into 4wd low? I'd try pulling the shift motor off and seeing if you can shift the t-case into 4lo with a pair of pliers and also check and much sure the shift motor is functioning properly while you have it off.

Also try flushing the fluid in there and replacing it with some synthetic ATF like Mobil 1.

ok i figured out what it was... my neutral saftey switch is not aligned correctly.... was at work last night looking the tranny over... and i locked the hubs, put it in neutral, put it in 4wd high, then tryied low... didnt work, moved the shifter towards reverse... and BAM 4W low now where the hell is this switch.... in the colum? or on the tranny?

That happens in my 99 sometimes too. When the shift motor is going out, I think it shifts partially into 4Low, and dropping into a gear decreases the resistance on the spindle breifly, so the motor finishes the shift. Anyways, mabey I wrong...
