when in park you can turn the output shaft ?

are the splined stripped out on the end of the output shaft that spline into the transfer case ?

Customer: replied 7 months ago.
they are
Expert:  Gary replied 7 months ago.

if the splines where stripped out on the output shaft the transmissions output shaft was the wrong spline or the transfer case was the wrong one with a different spline

they had 2 or 3 different plied output shafts

at this point both the output shaft and the splines on the input of the transfer case should be damaged and i would pick up a matched transfer case and transmission complete and swap them out so this does not happen again
