ahhh ok i think i get it for the most part, i just looked at the exploded view on my manual. and wow it looks super crazy and confusing. im definitely not gonna open the diff case. just the outer case to clean the bearings. thanks for everybodys help.

If you find water inside, I'd open the diff and make sure its not contaminated with water also. Water can thin diff fluid and your diff action will goes away.

They are not that complicated and you've done 90% of the work already just to get there. I never pass on a chance to make sure the guts in a diff is ok.
