well the reason is $ I guess I bought well after I sold some stuff that I got also like the s10, 400 and a few other things I have 100 dollars into the tranny, transfer case, front axle, engine(before rebuild), some other misc stuff from the s10, and my tires which have 85% tread left. I guess I never considered changing my x-fer case I was just thinking bombproof I guess but it does weigh a ton so it wouldnt be a bad thought.
