2008 Mid-Model Intermediate Drive Shaft (IDS) Seal Update

The IDS seal design was updated in the mid-model year 2008 Getrag 760/790 Transfer Cases.

Replacing the IDS seal with the correct seal requires identification between first and second design transfer cases. Refer to the table below.






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.
