Geeze on my Ford 2120, it was $1700 for a set of front differential gears installed when I (my ex wife) loaned my tractor out over 10 years ago and the guy beat up the front end. $400 is a bargin in my book /forums/images/graemlins/confused.gif
Also as far as the front drive shaft spinning, when you are out of 4WD, the drive shaft has no connection to the transmission, and is also not "hard" connected to the front end. I suspect it spins due to friction in the front differential.
