The light turned off, and i'm now in 2wd. The truck still feels really ...um. heavy?

You know how a truck feels more controlled/heavy/sturdy in 4wd. I still have that feeling but it's definately in 2WD. I even sloshed around in an empty snowy parking lot to be sure 4WD was disengaged. Could underneath the cause this? It's still really crappy weather, so i'm hoping this goes away.
