The front driveshaft will spin even in 2WD on anything 2000 or better. With live axles it spins the differential which spins the driveshaft. Does the light go out and how does it feel when you turn? You should feel a big difference in a hard turn either direction especially on pavement between 4 hi and 2 hi.
I like your thinking-that my truck is already v8 swapped hahaha. I'm spinning the input shaft on my bench and can't stop spinning the front flange without stopping the input shaft.
