The 473229 is the correct seal. (I HOPE!) I got it in. the hardest part was getting the old seal out. I did not have to use a gear puller to remove the yoke, it pulled right off. to break the nut loose I put it in 4X4 so the yoke wouldnt spin and used an impact. Not sure if thats the best thing to do because I remember reading about a tool used to keep it from spinning. put RTV on all parts listed in the link above and put it back together. I also read to torque it to 250lbs, my torque wrench only goes to 150. so I hit it with impact and went a little tighter. took it for a test spin and didnt see any leaks. I will keep an eye on it and see if it holds.
