I am sure some rebuilds are good, I just don't trust people sometimes.
New drive axles run a bit over $200 each. I think rebuild kits go for about $100 for both sides, so it's cheaper to rebuild, but if the axles are quite worn, I would just buy new ones (money conerns also need to be taken into account!).
Where are you getting the tools from? Sears sells a 36mm 1/2" drive socket, but 1/2 drive is a little small to break torque on that nut. I used a 3/4" drive breaker bar, 3/4" drive extension, and a 3/4" to 1/2" adapter to get the nut off. You will have to drop the car back onto the ground to keep the wheel from turning when you try to break torque on the nut.
