99 runner 4wd front diff fluid.

API - GL-5 SAE 90w

Wth A.D.D
75W90
Install under cover

What does A.D.D. mean ?
What if I can't find GL-5?

I'm replacing the CV shaft seal on the pass side and the fluid leaking out is pretty nasty so I figured I drain and fill.

Thanks Guys, Kenny S>

ADD is Automatic Disconnecting Differential.

If you read your owners manual, it will tell you.

GL-5 is merely a spec rating for gear oil. Its listed on the back of the bottle, and almost every bottle of standard gear oil out there is GL5 spec.

So I'm assuming that without manual hubs, I have automatic disconnect.
and I'll be going with the 75W90.

Thanks, Kenny S
