Making My Mint XJ Roadworthy Again and 4X4!

I acquired this jeep years ago and now with my channel I have a reason to drag it out and fix up. Its a 1999 Jeep Cherokee limited edition, but has a bad engine and 2WD. I just so happen to know a guy with everything it would need to be a mint 4x4. Interior is a disaster so that's a job for another day. Hope you enjoy so I can rebuild more in the future!!
