Hello everyone! I was looking on Craigslist and I found an engine from a wrecked GC with the 4.0l, and was interested in it because my motor isn't exactly up-to-par(208,600 miles). I would love to just swap in a replacement for now so I can work on stroking my tired engine over the winter. I'm not an ace mechanic by any means but I do know how to turn a wrench. Just weighing my options. From what I know this 2000 GC has the 4.0, 4x4, w/ 58,000 miles on the clock...my TJ has the 4.0l, Ax-15, np231j, and 4.88 gears with 35x12.50r15 tires. Do you all think this is a straight forward swap(out and in). Any help would be greatly appreciated. Have a great day!
