Hear me out. I've seen dirt cheap prices on T cases, D 44's etc. from Craig's list and salvage yards around me. My question to you guys is this.... Is it a cost effective approach to buy these parts, rebuild them on a bench while I happily cruise in my TJ, then swap out and sell my old parts? Seems like a no brainer. My ultimate goal is to bump my 04's D 30 and D 35 to 44's, w/ a regear. I know I'm going sac some money upfront, but I'll recoup on the back end, and my "down time" with my baby will be limited. All the surprises will happen on the work bench, not the driveway. Thoughts???
