Could that also be caused by the ball joints being worn-out from larger tires?

What would the alignment machine show? Camber out of spec?

Oh yes that is also very common but this particular jeep that's in the picture has a bent axle as I drove it just before it was bent. Typically ball joints that are wore out that bad similar to the picture are very high mileage units

Yes it sure will. It's really the only tried and true place to get a camber spec

The problem I have with using that to diagnose a bent axle is that I have taken multiple BRAND new JKURs to get an alignment, and ALL of them were out of camber spec from the factory. I am pretty convinced they weld the damn Cs on out of spec. I have seen it too many times.

And I have monitored the camber specs over the life of the JKURs with 37s and stock axles. The camber specs never changed more than one degree up and down. And these are JKURs that are wheeled all over CO and UT.

Agree . When I got my Jeep I immediately put it on our alignment rack and it was at the negative end of the camber spectrum . BRAND NEW ! Now after 3 years of moderate wheeling it's still in the same place . Figuring out what people consider to be excessive negative camber can be tricky without a baseline starting point. It can be bent c's , axle tubes, worn out ball joints or that's just the way it was built .

To tell you the truth unless something is radically worn out or wrong I don't sweat it too much.

So do installing sleeves and "C" gussets like the ones from Teraflex not help with running 37" on a dana 30 front end? Seems like cheap insurance if I'm already in there getting regeared or is it a waste of money?

I would buy those to put in the Dana 44 rubicon axles that you should swap into your jeep
