Need some help here. I want to change out the differential fluid. I know that the middle bolt on the bottom of the differential will allow me to drain the fluid. What I need to know is this. What do I use to get the fill plug out. I tried a 1/4 inch and a 3/8 wrench but neither fit right.

It is a fairly large allen wrench, I forget the size, maybe 7mm, maybe larger.........just bust out your allen wrench set.......

Thanks

Me being the smart shade tree mechanic that I am, I already drained the fluid. Oops!! Here's to the learning curve.

Turns out it is an 8mm hex. Which is good since my wrench set doesn't have a 7mm.
