ok is the shaft going from the front diff to the transfer case supposed to be slightly loose? i was underneath messing around the other night and i when i grab it and shake (dont laugh) it has play in it - i can move it back and forth about a quarter inch or so - i thought at first that the bolts might be loose that hold the two pieces together closesest to the tcase, but it wasnt the bolts its the entire shaft moving inside there
