Wow tbear, that sounds like a worst case scenario with a U joint breaking.
Well, I did the U joints, I didn't have to buy a new axle, I was able to do it with the U joints alone. They took a long time to do since the needle bearings kept falling towards the center of the cup, but I got in in eventually.
I didn't even need any sort of "kit". I called snapon and they had no idea what was meant about stakes. They wanted to sell the 12 mm 12 point socket to me for $40!
