Here you can see the axle shaft seal along with the copper washer and smaller spindle bearing seal. You can get the kit by Spicer. I'll post the part number later. You can also see the oil slinger/deflector that goes pressed into the axle shaft. It is on the left. You don't need to replace these if yours are in good shape. Mine looked really good so I just cleaned them up.
This is what your axle housing should look like if your inner axle shaft seals are in good shape and working properly...
There should be no signs of oil or grease around that part of the axle housing. The left side was another story, you'll see shortly.
Then I removed the lower ball joint nut and the upper ball joint cotter pin and castle nut. I sprayed good ol' PB Blaster in there just to loosen things up.
Here is a view of the spanner nut that you will see once you remove the upper ball joint castle nut. The new ball joint comes with a replacement spanner nut so go ahead and remove it. You need the correct spanner socket. I got mine from RockAuto.
