So i am going to change the fluid in both diffs coming up here soon and i know i need friction modifier in the rear but what about the front?? Is it safe to add it just in case or is it not needed at all??

I have a 08 STX 4x4 4.6L with an all stock drive train

Thanks guys

I believe you need to add it only to your limited slip rear end

Its not needed in the front at all but it wont hurt it of you add it. Alot of gear lubes come with modifier in it already.

thats what i was thinking as well....do you know how many quarts is it 3 like the rear?

Should be the same amount, since you have the 8.8 inch in the rear, its also the same in the front.
