I've seen on this forum where guys have paid ~ $400-500 for rear gear installation from their dealer and thought well hell, that's not bad think I'll get it done. So, I went to the dealer yesterday and talked to the service dept and they quoted me $800 just for install, that doesn't include the gears or shims or any other parts! You wouldn't think there would be such a discrepancy for the same work at different dealers. Called another dealer to get a price and was quoted the same thing. That's a lot to pay when they don't even warrant the gears when its done. So I decided to ask my local mechanic that does all the work on our other cars, a guy I've known and trusted for 9 years now, and even he quoted me $650. Maybe its just geography or something, seems like a lot of the guys on here that said it cost them $400 or so are from up north.
