My 95 F-150 called for 75-90w if I remember right for both axles. Since it’s my hauler and I built it to be able to plow snow, I put I think it was 80-140w in. Front is an open diff and rear has a lunchbox locker so no friction modifier. FYI, some of the new synthetic oils don’t require an additional friction modifier. My green Ranger is getting a limited slip rear and I’m going with a full synthetic that doesn’t require extra friction modifier, says it has it in it

Ok sweet. Thank you. I appreciate the input. And yes the amount of information that's so quickly accessable here is incredible. Here's a picture of my project.

Me and dad rebuilt this thing from the ground up,we did the body work and all, welded new panels in, did the paint job ourselves, re-wired the whole thing, and its finally all coming together.

That is my favorite truck body style.

Same here! It's definitely one of the best truck body styles Ford ever made in my opinion.

I have in the past drained a differential (or manual transmission), refilled with cheap synthetic automatic transmission fluid, driven a few miles and drained again. This was to help clean out that original lube and goop before refilling with synthetic. The synthetics are so much better in my experience.

If nothing else, they pour easier than standard gear oil does. And stinks a lot less.
