Default front differential top up

Hey guys. I was checking the differential fluid level today and I know the owners manual says the level should be half inch below the bottom of the fill plug when cold. If I put my baby finger in there, I cannot put it in far enough to get to the level. Should I just fill till fluid starts to come out the hole that way I will know it is full? Does it matter what fluid I use just for a top up as long as it is 75-90 synthetic? Thanks in advance.

While tonight I topped up the front diff. with castrol syntec 75-90. Would anyone have a manual that would show the torque for the fill plug on the diff? For now I torqued it at 25ft/lbs. Thanks

Just snug the plug up.... tight is tight... it really doesn't need to be torqued.

I fill mine until it comes out the hole.... about 2 quarts for the back.... and about 1 3/4 for the front. (from empty)

One small piece of advice.... always make sure you can get the fill plug out before you remove the drain plug.

every diff is about the same,fill it up till it comes out the hole,then just give the wrench a good grunt,like muddy said,tight is tight,theres no load on this so torque shouldnt really applyas long as its tight
