Front seal position checks
The front output shaft seal sits where the front driveshaft exits the transfer case, so it keeps lubricant in the case and keeps dirt out of the front output area. Leaks at this location often show up as fluid on the front driveshaft yoke or on the inside of the front axle area. Check the seal and the yoke together, because a grooved yoke can wear a new seal quickly.
Before installing, remove the old seal without scratching the bore and clean the seating area. Inspect the yoke or shaft surface for grooves, rust or pitting. Drive the new seal in square and evenly, then refill and check the fluid after a short drive. Compare the output position on your transfer case with the seal before final assembly.
