Change Differential Oil, and found a surprise
I decided to change my differential oil because I'm trouble shooting a slight howling/rotating sound that almost sounds like a vacuum leak when I drive from a dead stop. I read on here and a few other places that it could be the diff causing it, oh and the fact that I'm pretty sure the oil has never been changed.
Sweet damn does the oil in the Differential STICK! I Finally got the old stripped bolts out today to change the fluid and found a not so unexpected surprise. Not only was the oil completely black, but there was a piece of metal stuck to the magnet along with a ton of gunk.
My concern now is whether or not I have enough fresh oil in there. I could not figure out how to fit the bottle at an angle to fill it so I used a hand pump. For those of you that used of them you know what I mean when I say they suck. I would have to say I put a whole bottle in the the diff, but I think it needs more and I'm really not sure. How do you guys fill it up?
Here some pictures of my drain plug.
Now this is the plug with the metal piece on it and honestly there is 1/3" of gunk on there
Here is a picture of the piece that was stuck on the magnet
Oh and changing the oil helped with my howling issue, it no where near as loud, but still there.

Make sure the car is level and then fill it up to the bottom of the fill hole...if it starts flowing out, it's full. Put the fill plug back in and you're done. Since it's never been changed before, change it again after 5-10K miles and you should be good to go for awhile.

I'm concerned about where that piece of metal came from attach to the magnet, on the upside there was no metal shavings in the oil itself so hopefully that is the only broken piece..........................which I doubt

Its a 10mm allen key, if you purchase a new one from Toyota the drain plug is not allen head its a 3/4" socket.
Spitfire86, I checked a few places and all they have for filling or anything of the sort is a break bleeding kit
NOTE: Here are the part number for new drain and fill plugs from Toyota. Also there are crush washers that need to be replaced when changing the fluids
90341-18044 Plug Drain
90341-18032 Plug, Fill
12157-10010 Gasket
