Someone could have added oil not knowing what they were doing

Blow out the diff vents, if it is oil from diffs the vent is clogged

After I adjusted my swivels the ball seals started to leak a little, moves the slightly from where they are used to sitting

 

I got everything apart. It looks like I'll be replacing all the seals, wheel bearings and the swivel bearing. The CV joint as well.

 

My upper thrust washer was gone.. missing. The bushing that the locator pin rides in is also trashed.
