Default I am unsure/confused

So I want to change the rear diferential fluid in my Mazda B3000 4x4. I was not sure if I had a limited slip diff or an open diff... I looked at the tag on the diff and it said 4 10 & 8.8 which means 4.10 ratio and 8.8in gears. According to my owners book, that means I should have a limited slip but according to the tag, there is NO "L" between the 4 and 10 so it is an open diff...

I then proceeded to lift the truck up and spin the tires and here is the video and what I got from it...


What do you guys think??????

Thanks

Thanks! I hate the uncertainty and a mechanic said it could damage if I put the limited slip additive in anyhow so I wanted to make sure!

I don't see how putting additive in an open diff. would hurt anything other than your wallet for the added, unnecessary expense.

The above test is a good way to check if the previous owner did an upgrade or kept it stock though.
