So my service manual and royal purple said my diffs take 2.45 qts. i got to about 2.10 and it started coming out the fill hole. whats the deal? i dont want to over fill and right now it is literally at its max, right level with the base of the fill hole

 

You just fill it up to right below the full hole. Ovefilling will cause gear oil to come pouring out everywherreand overrun your seals

 

so if it is sitting level and not coming out the fill hole its ok? or should i suck some out? so i was adding the .45 when it started coming out of the fill hole so it stopped leaking right when it got just a hair below the hole obviously. that too much in there?

 

JUst below the fiill hole. like once it start barely coming out of the fill hole youre good. Stop. Put the plug back in.

 

ok thank you, i didnt want to drive it if it was at all off

 

Drive is a LITTLE BIT, then recheck the fluid. Sometimes it takes a bit for it all to go where it wants. Driving it with low fluid gets expensive quick.

 

yup just fill her till she drools then plug it back up. also add some rtv to the plug lip so u dont have that ugly leaky plug
