bent my differential cover -- plus fix
Bigger images are here. Bent the bottom of the differential flange. Without a rock guard, it was bound to happen eventually on some of the 'roads' I drive. Very minor leak though. Old vs...

...nice job Cal! Those massive 10.5 and 11.5 GM Corporate (later, made by AAM) diffs are freaking awesome. I think that the Allison 1000 tranny with Duramax comes with the 11.5 inch rear end in the 3500?
The only thing with these big 14 bolters is: ....you know a GM Corp axle has been down the trail when you see plow furrows down the middle of the offroading trail LOL...
I think the only way to get that pumpkin higher off the trail is with very large diameter tires (and a change of ratio to ~4.56 with ~41-9 teeth...and fly-cut that big housing down an inch or more-ish).
The gear oil quantity is very well known for those diffs...after you put in the correct quantity, you bench-mark the level through the filler hole with a 90deg bent white wire tie..marked with indelible black marker..and throw that new tool in your glove box :D
