Front Diff Hex Key Size ?

[greasefingers]

Hey! I am changing all my fluids. My 2003 T4R has 30k miles on her. I am having problems figuring out what size hex key fits in the front differential plugs. The rear has lager bolts but the front has allen-key type. Today is a warm and perfect day in New Jerzey for maintenance. Anyone know this. Many thanks.

If I remember correctly it is 10mm key. For both fill and drain plugs.

Well that sounds about right because my 3/8” (0.375”) hex key was too sloppy and 10mm = 0.393”. I will run out and get one before it gets dark. Thanks again .
