My Dana 44 came with Trac Loc and as someone pointed out its probably shot after 81k miles. I'm trying for now to keep this Jeep simple, frugal and effective. It already came with a Dana 44, a blutooth stereo and an aftermarket amp. I'm cutting down the bumper and adding a winch plate, and I'm part sourcing a 2" lift so I don't have to pay $1000 for a kit with shocks I don't want. So the question is, rebuild, replace, or simply buy something like a true locker?
