The seal stays stationary in the housing where the pinion enters the rear differential. Its sealing lip rides on the rotating pinion yoke to hold lubricant in and keep contaminants out.
SKF invented the first integrated shaft seal in 1928 and has continued to develop new designs and bonding techniques since then. Its seals are built to specific designs with premium materials chosen for each application and its operating environment.
Signs this part may need replacing include gear oil seeping where the driveshaft meets the differential and an oily, grimy film building up on the housing. Diagnose the source of the leak before replacing the seal.
