What are the differences between good Evo's and bad Evo's??
Not untrue. The transfer cases are stronger because they have the limited slip and do not contain the weak spider gears that break so often on the 03-04s. Also, there were many TSB updates to the transmission which were completed on the 2005s while many of the 03-04s still dont have them done. Mitsubishi fixes a lot of little things they dont always mention to the public, paticularly because they dont want it to seem like they sold things that were not reliable. (Ironic).
