Drive Shaft seized on the final drive splines

[Grumpy Goat]

With the weather starting to warm up I decided to start into this project today. Temp is about 43F and sunny. I ignored the advice to look in the front boot before dropping the back end and the rear did not want to drop easily. Soon figured out that it was the spline not disengaging that was the hold up. So a little encouragement got that fixed up. Some observations:
- No water in there at all but there is dirt!
- No lube in there at all and there is some corrosion.
- No snap ring in evidence at the front end.
...

I like the bit about the "little encouragement"

Thanks for the excellent photos (as usual) ... you did have some rust in there. Do you think that you'd put some rust remover on first before greasing up?
