I replaced the e-locker actuator with a cable actuator 3 years ago. Works great, way better, I’d do it again in a heart beat.
I found a complete Waggy Dana 44 about 8 years ago for $250 at a wrecker. I’ve considered selling the d44 and opting for a Toyota based axle housing like Trail Gear offers, but there is nothing wrong with the waggy axle and its relatively easy and slightly cheaper to build. The carrier will be a PITA to install, I need to find a housing spreader to fit the carrier shims. If I can’t do the install at work I’ll probably have a shop do the install.
