I've been hard on my DD lately so it came as no suprise to me when the rear axle started making funny noises. I pulled the cover two days ago to see what was wrong. One of the bearings was totally blown apart, leaving metal shavings and remnants of rollers all over the inside of the diff. I laughed, thanked my lucky stars it was ONLY a 10 bolt, and proceeded to jack the truck up and pull it out. I figured it'd be easier and cheaper to just put a new one in than to have somebody rebuild the current one. I got done pulling it last night and figured I'd go call some junkyards today, pick one up, and have it back together and running by suppertime. I start making calls this morning and can't believe what I hear. Out of 10 yards I called, the cheapest anyone would go on a 10 bolt with 3.73's (we're talking without brakes and axleshafts here) was $450!!!!!!!!!!!! I about **** my pants. When I started laughing, the guys on the phone seemed insulted. I then remembered the 12 bolt I'd pulled out of my project truck and given to a certain yard because I couldn't sell it for anything and I didn't have the space to store it. The guy said yeah, he remembered me, but it'd cost me $500 to get my axle back. Wow, I'm furious. What do these piles go for in yards around you? I would hate to ask what they want for a 14 bolt, that might run upwards of $1k.
