Seal DesignSecond design IDS seals have sealing lips extended about 5-mm (0.20-in) from the firstdesign sealing location.
Second design IDS seals are not compatible with first design transfer cases. Installinga second design seal in a first design transfer case will create a transmission fluidleak due to interference with the input shaft.
