Hey everyone, I have a 2016 mustang GT 36k miles with a Performance package. I have the torsen differential with 3.73 gears. Today I was changing the diff fluid and when I pulled the plug there was this piece of metal stuck to the magnet. Anyone have any ideas as to what this is?
It appears suspiciously like a "turning" produced by a cutting tool, like a drill bit. Likely a manufacturing chip which did not get removed during final cleaning. BTW, such a piece of metal is capable of breaking teeth off a ring gear.
