Gear Oil...how much is too much?
 

On my donor 1/2 ton rear, there is no filler hole. I slowly re-filled the rear end through the side mounted drain hole until the oil starting coming back out. Is that enough??? Does any one know the capacity?

350 4-bolt with goodies.

believe it or not, that is the way it is done, just fill it up till it comes out the filler hole.

Yup , thats the way I have always done it.

Thanks fellas....I can rest easier now!!!
