IDS Seal Identification

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

Second design, post-breakpoint seals were built with IDS seals that have green shaftguides-(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 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.

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 toFront Drive Axle Inner Shaft Seal Replacement.
