This is what I get for thread pimping!! No shiloh i'm using valvoline full synthetic w/the ls additive already in, per the web site. ( the bottle didn't say shlt!!)I previously mentioned it btw.

 

Dude, I'm 17 do you think I listen to the wise ol' farts? lol

 

the sludge you seen along with small metal "shiny" particles is completely normal for the rear diff. Gray, slimy sludge more than shiny particles, but at any rate....completely normal. it's when you see chunks that you can physically hold you need to worry about.
The shiny particles are wear from the bearings...gray sludge is wear from the gears.

 

Shiloh you ought too! you will be here, mark my words. But at any rate thanks for the posts.
Ddog what can I say you make my heart go pitter patter, What a relief.yeah I could tell it was virgin ground,(easy ramhunter)When i tore into it lol

If I remember correctly every 30k for synthetic and 15k for conventional
