Macka, there's very little reason for swapping in a Ford 8.8 from a Explorer or Ranger, the gain in strength would be infinitesimally minuscule in contrast to the Dana 35. And, the Ford 8.8 would burden the installer with another disreputable C-clip shaft unequivocally debilitating any endeavor to build an axle of sufficient strength to handle the unsprung weight of a 36" tire, and, to only upgrade once. Too many times, four-wheelers build marginally which commonly results in frequent repairs and costly upgrades. Frankly, what is required to support larger tires and axles under the Cherokee's unibody should be the major discussion. Personally, I would not even consider upgrading a Cherokee for moderate and/or difficult trail use. The money the owner will spend upgrading the Cherokee, if done correctly, would be sufficient to purchase a new Wrangler.
