Do I have a ADD diff? Which diff fluid do i use?
Hey guys, getting ready to change out all my fluids on a 92 manual 3VZE pickup.
Reading the FSM is says to use Toyota Gear Oil Super if I have a diff with ADD? If I don't have and ADD, I can use regular GL-5 gear oil.
Is there an easy way to know if I have an ADD diff? And if I do have an ADD do I use the special toyota gear oil in both the front and back diffs - or just the front?
Thanks very much if anyone can shed some light on this for me.

You dont have Auto-Hubs. You have ADD. Auto Hubs were only available on Toyota p/us from '84-'88 and 4runners '84-'89. To know if you diff is ADD or not, look at the front of the front diff. If it has a little actuator thing on it, then its ADD.
