### IDS Seal Identification

First design, pre-breakpoint seals were built with IDS seals that have yellow or blue shaft guides and are replaced with unique, short neck seals (1) with a green shaft guide.

Second design, post-breakpoint seals were built with IDS seals that have green shaft guides (1) and are serviced with unique, long neck seals (2) with green shaft guides.

### Seal Design

Second design IDS seals have sealing lips extended about 5 mm (0.20 in) from the first design sealing location.

Second design IDS seals are not compatible with first design transfer cases. Installing a second design seal in a first design transfer case will create a transmission fluid leak due to interference with the input shaft.

### Seal Installation

Installing the replacement seal to the proper depth is critical. Use DT-48078 Inner Drive Shaft Seal installer with J 8092 Driver Handle to install the seal 2.8 mm (0.11 in) (a) from the end of the input shaft. Refer to Front Drive Axle Inner Shaft Seal Replacement .
