dana 44 HYDRA-LOK ?????

off topic for sure but curious if anyone has any experience with this set up. we are putting new bearings on the pinion and carrier in the rear differential of an 01 jeep grand cherokee. i tore it down yesterday and noticed a wierd tin plate on the driver side of the carrier with a couple of small ears and a small wing on it. i was cleaning it in the parts washer when i noticed the plate would rotate. i flipped it over and saw the words HYDRA-LOK cast into it. there is a series of holes in the carrier under the plate and i assume it acts as a hydraulic locking device???? the differential is an aluminum center dana 44. anyone know how it works or if it would work in the front 44 in our trucks??? first one i've ever seen.
