anyone know how to replace a 1/2 axle on a 1992 subie?

The wheel bearing finally went on my scoobie. I have never been afraid to drive any one of my crap cars but this takes the cake. So I need to replace the 1/2 axle because the cv is going and you need to press out the wheel bearing to get the stupid axle off, so I might as well kill 2 birds with 1 stone. However I don’t have a garage and my usual mechanic is booked for the next two weeks. Little help? I have the parts already, and keep in mind I am in the poor college student catagory.
