Bought a Dana 30 to build for my '69 Bronco. Yes, I know they're weak; it's just a stopgap measure until I build a D44.
Anyway, I pulled the front cover yesterday after work and found some carnage. Fook.
There were a few smallish chunks of metal in the oil when I drained it; some were just a tad larger than coarse ground salt bits.
Several of the ring gear teeth are chipped on the end.
The cover showed signs of internal violence.
Several ring gear bolts showed evidence of a meeting engagement, and a bunch were loose! Not even finger tight. Whoever reassembled this sucker needs a class on torque specs and Loctite, I think.
I don't think the seller knew anything about this, and it's not a huge deal, since I only paid $75 for it, and I still have the complete Dana 30 that's installed in the Bronco now. Should be able to make 1 good diff out of the 2.
Anyone want to take a guess as to what happened? The loose ring gear bolts could have caused all kinds of problems, I guess.
