Phil, 2.6 pints in front diff not enough...

[tomp]

I did try the old finger in hole trick, but didn't fell anything

MM, I would go ahead and get an extra quart just in case you have same problem. I ordered 6 as well and can use more, so now I have to go buy another in the morning and hope that works. Plus, you will have some if you detect a leak or need to add etc.
