1078A1 Drivetrain

[Awesomeness]

Wow never seen a LMTV with the block cracked back there. Does it run? Very definitely a lemon. More like humpty dumpty.

That block crack is the EXACT same block crack on every one of the trucks with driveshaft vibration problems. It goes from the oil pan bolt up, turns 90°, and then to the bellhousing bolt. It was identical on mine, as well as several other posts here over the years. (PSA: Read my common problems doc here in my signature.)
