87Warrior Posted November 1, 2015 Posted November 1, 2015 I want to upgrade to a 231 tcase in my 86 MJ that has a 207. I currently have a good 231 tcase from a 91 with the electric speedometer sending unit that I would like to convert to a cable driven sender. I need the gear driven parts that bolt on the t-case tail cone and the tail cone from an early 231. Willing to buy a whole parts 231 if you are relatively close to Kansas. Thanks!
mvusse Posted November 1, 2015 Posted November 1, 2015 Get a cable drive unit from any older 231. You don't have to swap out tail shaft or tail housing, it will be a direct swap involving 1 single bolt. Even one out of a 2wd AW4 should work, exactly the same. I wouldn't be surprised if your old one from your 207 would fit as well.
87Warrior Posted November 2, 2015 Author Posted November 2, 2015 I did not realize the tail housings were the same for the cable/electronic 231, thanks for the tip. I will check to see if the 207 cable unit will mesh with 231. I was under the impression the two were not the same length based on some limited research. But hey, I will try the easy way first!
