MrSimon Posted November 29, 2015 Posted November 29, 2015 Will a 231 transfer case from an 87 MJ with the 2.5L 4speed be a direct swap into an 89 MJ with the 4.0 AW4? Both trucks are 4x4.
88whitemanche Posted November 29, 2015 Posted November 29, 2015 Aslong as the spline counts are the same....
Crash Posted November 29, 2015 Posted November 29, 2015 Should be plug n pray, ax4/5 are 21-spline, same as renix AW4. The only potential issue would be the input shaft length of the T-case. If it's too long, could be as simple as cutting down the input on the T-case though.
