02' XLT Rear Diff

[02FoExplo]

I have 3.73 limited slip and want to know about how much gear oil really should be in the diff including the 4oz bottle of friction modifier.

fill it to the bottom of the hole in the rear. i would put the friction modifier in first tho. but fill it till the fluid starts to dribble and put the cap back on.

I have read on other threads that when they take the top plug out a few onces of oil comes out. So when they added oil back again they added some through the vent tube on the top. Is this necessary?

my manual says 1.5 liters, including the 4 oz.

And the guys above are right, fill to the bottom of the check level (upper) plug.

You have links to these threads?

I just got my 02 XLT like 2 weeks ago, I do hear a slight whine, but its not overwhelming. I know I'm going to have to repair it sooner or later. I should of researched more. I owned a 98 XLT which I miss, It was totaled in an accident. So I went ahead and purchased a 02, which I love.
I know the rule is to fill up to the fill hole just wanted to make sure Ford didnt do otherwise.
