We toyed with the idea of rebuilding the AX-15 and the Dana 300, but in the end, time constraints and budget limitations forced us to roll the dice. We knew the transfer case was fine, and the AX-15 proved to be flawless. We swapped the funky Torx external hardware on the bellhousing for normal Grade 8 stuff, but were careful to torque the bolts to factory specs since the AX-15 bellhousings have a reputation for cracking. It’s also a good idea to leave the crank position sensor out until the drivetrain is installed to avoid damaging it. We stabbed the whole assembly into the Jeep as one unit.
