I checked the end play in the final drive axle and it was greater than the specs in the manual. The castle nut was also loose but still had the cotter pin in place, so I decided to pull it apart to inspect and clean the housing up.
When I was checking the end play I noticed the large final drive gear would slide on the axle shaft about 1/2" to 3/4" back and forth.
The Service Manual shows three parts that I do not have on my final drive axle:

- Part 9a Snap Ring, definitely not installed
- Part 9b Spacer, definitely not installed
The parts manual only shows part 4 (spacer) and 9 (Snap Ring), but no 9b-spacer.
