Things you will need

Seal I used from Advance Auto--part #470331N (Federal-Mogul)

1 1/8" socket for pinion nut

3/8 socket for u-joint

Tape to tape up caps on u-joint (don't want to lose the innards)

Drain pan to catch gear oil.

Breaker bar, torque wrench, impact wrench if you can round one up.

Paint or something to matchmark before removal.

Your starting point will probably look something like mine did

You'll want to clean up a little under there, and then mark what you've got so it goes back in the right place. I used yellow paint because I had yellow paint.

Next, remove the u-joint and tape the caps so you don't end up crawling around under the bird looking for that last little piece. If I'd had the money, this would have been a great time to replace the u-joints.

Now for the fun part. You SHOULD use the torque wrench to check the torque it takes to break the nut loose, and then re-torque to that spec+5. Wasn't happening for me. I couldn't even break it loose with a breaker bar and my legs. Borrowed an impact wrench and socket (1 1/8") and had to really lean on it, let compressor catch up, and lean on it again.

Finally got it.

Removed the yoke by gently tapping it out, alternating side to side.
