Nope. They are "open," meaning that the tire with the least traction will receive the most power. Same for the front. Lift a tire and the planted tire will receive no power.
If you want locking diffs you need to install them.

this one i drove the wheels sounded like one was skipping while cornering but only in 4wd

I'm not sure what a skipping sound is
But what you're probably hearing is driveline binding. Whenever the front and rear axles are tied mechanically together there is no flex, so normally in a turn the rear wheels drive a shorter distance (cheating it's called), but since they are mechanically locked to the front wheels, they HAVE to go at the same speed, so either the rear has to make itself slip, slightly spin one tire (to make up the speed difference since the front will be spinning faster), or the front must drag. Depending on how much traction each has will determine which of those occurs. Normally the rear does something since the rear on a truck has little weight.
With open diffs this happens pretty easily because only one tire of the rear needs to spin at all, since the two rear tires aren't mechanically locked together, just the front and rear axles, or better said the driveshafts are locked together.
On a vehicle with locked diffs front and rear this becomes more of a problem, since with EVERYTHING mechanically locked you can't just spin one tire and have the driveline binding relieved, you have to spin both back tires slightly...much more force on components...on dirt roads not a big deal, but on pavement, bad things can happen...
Good Luck...
