Im looking at this 97, 4 banger wrang, its got a engine from a different jeep and (120,000miles on it) and rebuilt transmission clutch and t case 2 years ago. The jeep itself has 180,000 miles on it. I didn’t get to test drive it yet but 1 of the first things I noticed is when I turned the driveshaft by hand it moves freely and turns easily about little more then quarter of a turn and then stops and then I can move it back. Same for the back one also. What can be the problem? What should I look out for in this jeep? Thanks!
