An Inner Axle Seal is pressed in the inboard end of each axle tube, right next to the differential side bearings. These seals contact the inner axle shafts to prevent gear oil from running out of the differential and down the axle tubes. Old age, blown axle u-joints, and/or grit that works it's way into the axle tubes and cuts the seal are the usual causes of failure. A bad Inner Axle Shaft Seal can be detected by oil coming out the end of the axle tubes next to the axle shaft u-joint. Usually when these Seals start to fail, they will seep oil so the leakage may go undetected for quite some time. Many a ring and pinion set has been burned up from axles that lost all their lube when long term seepage was not noticed.
