Why do you think it needs rebuilt any way. I think it's more likely you have a wheel bearing going out or need to replace brake pads. Before you spend the money on a rebuild think about buying a used diff. 410's should be less then 100 for a front diff. And avys lock right is like new. Bet he'd sell for about 150
