Re: differential fill/drain bolts

i seem to remember that it is a 17mm hex.  I have both an Allen wrench
and a 1/2" drive allen head socket in that size (as I remember, couldn't get
at the differential drain with the socket, needed the wrench).  Both are 

Might try ordering it through a friendly local car repair shop, if you are
friendly with one.  I believe snap-on will sell to general public if you
can find an outlet.

Other possibliity is Sears; they might have one.  Also LARGE auto parts

Might help if you told us what vehicle this is for.  Book sez Quattro 80 and 
90 models take 3.0 US quarts.

Also, CHANGE THE REAR DIFFERENTIAL FLUID.  did mine at approx.
90,000 miles; stuff that came out looked like molasses.  This takes 0.79 qt.

Tranny and rear differential oils are not the same, by the way.  Tranny sez
to use tranny oil G50, SAE 75W90.  diff uses GL 5 (MIL-L-2105B), SAE 90.

 Subject: differential fill/drain bolts
        Hey netsters,
            I want to change my gear oil out again, and I am wondering what
 hex-wrench I need to get the drain/fill bolts off.  I have done this before,
 t I borrowed someone else's tool last time, and I don't remember what size
it w
 as.  I also don't remember how much I gear oil I used.  Does anyone know
 how much I would need to buy to fill both the front and rear diffs?  Also,
if a
 nyone knows where I could get that large hex-wrench (allen wrench)?
             I changed the gear oil in the gearbox and front differential
 a year ago with Amsoil synthetic, but I would rather use Redline MTL and I
 r changed the fluid in the rear differential.  Well, any help would be
 ted.  Thanks in advance.
