Moving on to the back, you can easily see that this truck had a long-standing problem with leaking rearend fluid. You may also notice this one sports a heavy-duty rear axle package, so it's equipped with a Dana rear, even though it's only a 10-Series truck. On either side of the center section there's a factory weld that mates the actual center housing to the axle tubes. Somehow (like abuse maybe?), both welds were cracked, and gear oil leaked like crazy. Speaking of crazy, somebody tried to epoxy the welds-didn't work too well, though.
