$55 each at Autozone! Even cheaper at NAPA (believe it or not). And the Autozone's come with lifetime warranty.

You will need a 37mm socket and a breaker bar to brake the hub nut loose. After that, the only special tool you'll need is a ball joint separator. You might wanna have a good wedge handy (although I suggest rebuilding the driver side axle into the old cv joint housing if it's as much a biitch to remove as mine was).
