Diff Oil change?

[Finsdad]

I figured while Im doing everything else might as well change the diff oil on my 05 QuadKing 700. I looked in the manual thanks to AJMBOY. Im wondering what  you are using? I would like to use Amsoil since all the other fluids are that. If not just something good. I pulled the plug on the rear and its a little dirty but not bad. I just want to start from scratch so I know what I have.

Will Royal Purple Max Gear 75/90 work? It says it will in both front and rear?

My 2008 calls for gear lube in the front and GL-4/Wet brake fluid in the rear.  Being new to the forum and Suzuki ATVs, I don't know if your 2005 uses enclosed rear brakes as my 2008 does.

I have used Mobil 1 75W-140 synthetic for years in my trucks.  I chnaged the front diff lube in my 2008 to that.  For the rear, I went online and checked major auto parts stores until I found GL-4 and "wet clutch" specified.

Although my trucks have been here a year, the ATV will experience its first interior Alaska winter with the new lubes (and 0W-40 Mobil ! in the engine).  -30 degrees F and below will be the ultimate test.
