Here's a nice dumb one:
I just wrapped up ball joints and axle joints on my 1999 4WD NP231 AW4. Everything seems to have gone smoothly. I reinstalled both axle shafts with very little trouble... being careful to mind the seals and engage the splines at the ends.
I just put the tires on (vehicle still on jack stands) and noticed something:
Each front wheel spins freely. There is NO diffential action (i.e. one forward; one backward). The tranfser case is in 2WD. If I turn the propeller shaft by hand, both wheels spin together (forward or back but the same direction)... the drivers side seems to spin just slightly more when I release the shaft.
When I put the TC into 4WD Hi, I cannot turn the prop shaft by hand and I get differential action when I spin the tires by hand. I *think* that's normal.
It's late and I'm tired and I just can't freakin' remember if both wheels are supposed to spin free in 2WD. This is awesome... I can change a ball joint but I can't remember how a diff works. I'm just freaked that somehow I did not engage the axle shafts into the differential properly although I have no idea how that's possible. I just always thought the Dana30 had differential action on the wheels even when the TC is in 2WD.
Did I screw up or am I just too tired?
