2005 subaru legacy 2.5.  What parts do I need to do this?  Are there crush washers that I need for any of the drain plugs/filler plugs?  Anyone know what sockets are needed for the front and rear?  I've seen videos online where its a square and the other is a torx?

loosen the fill plug on the rear BEFORE the drain. I used a floor jack on the handle of a 1/2" breaker bar.

 

some gear lube comes in squeeze bags now but, when I did the rear, I used a pump kinda like this;

 

Not what was asked, but here's a useful tool for oil-filling:

You can often find a Turkey Baster at low-cost at dollar-stores.

Useful for filling or topping-up of rear-differentials. And can help with adding oil down the dipstick-tube of some manual transmissions.

oh, the torx you may need would be a T-70, same crush washer as eng. oil (20mm ?)

local parts store or amazon, etc.
