I have a 1989 2.5l 2WD swb Comanche that has nearly 300,000 miles on it. The motor and transmission both need to be rebuilt. I have found an 1986 Cherokee that also has the 2.5L inline 4 but is 4wd with a 5 speed manual. Would there be any major problems i might encounter when it comes to swapping the entire drive train (Engine, transmission, transfer case, & front axle) from the Cherokee to my Comanche?
