Axle Splines a Little Rough??

Going by the pics of the axles I have to say that's an odd one. I've pulled numerous rearends apart and haven't seen axles do that. I wonder if it was ran low on gear lube at some time in it's life which caused overheating and pulled metal chunks off?

Can you get a pic of the side gear splines? If there as bad as the axle splines I don't think I'd put $500 axles in it as the side gears may break and ruin the new axles.

Are both sides like that?
