So I found out the nice old man 'blasting the rear axle case somehow lost one of the outer flange studs (it must've shot out like a rocket when the sand stream hit it and now lives in a dark corner of his shop under an old some old pipes stacked behind a 55-gallon drum or something).
I was at O'Reilly Auto Parts last night after playing our Community Band concert getting something for the Ram, and one of the guys said he had come in looking for a replacement and was all upset about losing it. Man, I feel bad now: I dropped it off Monday afternoon and told him that I needed it by Friday - I also told him I realized it was short-notice and I know they're busy so if he couldn't get to it, let me know and no worries. He stayed late yesterday to get it done (Dang - I wasn't expecting it until Friday).
I called him this morning and told him not to worry about it, that I'll just get a new one. But wow - my axle case is done! Can't wait to get it all back together and stuff back under the car this weekend!
