Tech Note 2: Input/Output Seals
The original Rockwell T221 Transfer Case Seal was a low temp rated, opposed Double Lip/Double Spring Seal that was 3/4" wide and it protruded out from the bearing retainer about 1/4". QU30300 is a high-temp single lip seal that is 5/16" wide so 2 seals can be stacked in each bearing retainer. For maximum oil sealing, I recommend you stack the two seals consecutively with the open side of the seals towards the inside of the transfer case and both seal faces toward the outside. Installed this way, you will get double the sealing effect compared to a single seal which is especially important if you have worn yokes or loose bearings. If road splash is a problem, you can install the 2 seals face to face to mimic the original Rockwell seal. When installed face to face, the inner seal keeps oil in the transfer case and the outer seal seals out road splash and debris.

The Rockwell T221 design is from the 1950's. Its 4 shaft design was not designed for constant modern highway speeds. When operated at higher speeds for any length of time, the T221 runs hot enough so conventional 250 degree rated nitrile oil seals often fail. QU30300 is a 300 degree rated, premium polyacrylate seal that is compatible with both conventional and synthetic oils or Extreme Pressure gear lubricants.

This kit includes one seal per yoke. If you wish to double up on the seals, order additional QU30300 seals.
