Re: Rockwell t221 gear slop
Something I forgot to mention that you might find interesting. While I was doing all the above mentioned swapping and fixing etc, I ran the truck for quite a while without the x-fer case installed. Figured I'd check the gas mileage and then compare when the case went back in. Believe it or not it averaged 13mpg with or without that crazy inefficient counter shaft style case. Go figure.
