I think the area that looks cracked in that picture is actually the parting line from casting the housing. I inspected it pretty closely and didn't find evidence of cracking in the areas that are gouged.Looks like the case is cracked. Good thing that you bought a new diff. Too bad it is the wrong gear. 285 with open R180 seems to not work. I need to get that lokka locked diff installed
Did this guy ever come through?
Nice! I hope you're able to get them installed soon. You'll have to let me know how you like the gearing. I've definitely heard more positive things than negative.I have 4:10 gears and a Lokka to be installed. I have strong axles (300C) but stock CV’s. Just had not been well enough to install. Plus I need to make a pinion depth tool.

Yep, it's just the parting line from the sand casting. It definitely worried me at first.To the left of the pinon that isn't a crack? OK.
Mojave to SLO that is a long drive. I think I would have pulled the driveshaft and CVs for the drive home.
Yes the CVs would then be the weak point but they are cheap and easy to replace. Diffs not so.
