When I'm in 4wd, turning the wheel/taking a corner without stepping on the gas is like stepping on the brakes...the truck just stops. I've only had the car for about 6 weeks, so
I'm not familar with this...is it normal? It makes parking a hell of an experience. At first it didn't concern me, but tonight I did a 360 in 4wd and the car lugged and pulsated. It certainly seemed incorrect. Any ideas?

When I first got the car, something with the 4wd was broken (I believe they said a washer was cracked) that caused the car to not engage/disengage 4wd properly, and loud noises and lots of lugging resulted. Not sure if it's at all related...
