As far as I know it is a regular axle. I do not know how to tell if it is Limited Slip. I bought the truck used so I do not have an invoice with a list of options.
As far as fluid, I started to take the rubber fill hole plug out, and fluid came running out, so I think it is full. I bought the truck at 44k and it is now at 86 K and I have never changed the fluid.
The sound seems to get higher pitched as the speed of the wheels increases.
