Should front drive shaft turn when in 2HI on 1997 jeep wrangler?

Well, honey, if you’re in 2HI on a 1997 Jeep Wrangler, that front drive shaft shouldn’t be spinning like a disco ball at a '70s party. In 2HI, power is only going to the rear wheels, so that front drive shaft should be taking a nap and enjoying the ride. If it's doing the electric boogaloo when it shouldn't be, you might want to have a chat with a mechanic before it starts charging cover for its performance.
