P0305 is a misfire on cylinder # 5
C0305 is an ABS sensor out and so on.
The reason I was asking for the whole code #
none of the two codes has any thing to do with the 4x4
if it is a used transfer case that they used
chance is the encoder motor is bad
very common problem
they are so common GM but out a TSB on it
good luck !
