Yeah, it probably has full-time 4WD with a viscous clutch at center - when you turn, your axles lock, and 3 out of 4 wheels will have to slip to let you get anywhere. This will cause jumping and tire noise. Engine torque won't change much.

LSD's front and rear makes this worse, but center is the most important when it comes to on-road maneuverability.
