So I'm going to be replacing the Diff covers this weekend with riddlers and I wanted to double check how much Gear oil people are using up front for the D30 and rear 44. I have the 2010 Sport

 

You will need 4 quarts to do the job. Front 1.5, Rear 2.5
The front d30 Riddle cover has the drain hole low enough to fill the fluid until it
comes out. Should be around 1.5. The Rear should be around 2.5-2.8. Fluid level should be at center line of axle. Mine was good at 2.5. Do not fill the rear until it comes out or you will have fluid coming out the breather hose.

 

Thanks guys.

 

I used 2.5 in the rear and all was well.

I used 1.5 in the front and it ended up puking a little out of the vent. Made a hell of a mess.

next time I'll use a little less in the front.
