Front Diff

[IndyNova]

So my nightmare summer with my truck continues, after going through a transfer case, new brakes all the way around, new rear drive shaft, new suspension..And multiple tows home.. I lost the front U joints on my front driveshaft and consequentially bent the drive shaft and broke the header..New driveshaft made and installed and drive it to check it out.. Everything is fine, get it back home and shut it off.. then suddenly the front differential starts pissing fluid on the ground ?.. Haven't looked at it since, but I'm guessing there's a hairline crack that expands when it gets warm and leaks fluid. What front diffs swap over? I know I'll need to switch the gear set to a 4.10, but hoping I can go to the yard and pull a diff from another silverado/sierra/escalade etc. Any help is appreciated.

Found the crack on the passenger tube, swapped it out with a front diff from a denali..Back on the road
