Nope, worm gears are in torque sensing differentials. There are 4 spider gears per differential, and they are different between open differentials, and limited slip ones. Two of the gears are splined to take your axles. The other two gears rotate on the cross shaft. If your rear end is stock, you need 28 spline axles. They can be had from many vehicles, such as any MN12, some Rangers, and F150s. I have some from my old diff, if you want them.
