DETAIL

Experience has shown that the differential pinion seals in 1994-96 Discovery vehicles can leak. The following procedure will replace the seals with an
improved seal kit. If one seal is leaking, both pinion seals should be replaced.

The diagnostic steps and repair procedures detailed in this bulletin were developed as an element of the Land Rover Way Operation PRIDE. This TIB
provides a library location for PRIDE information within the Land Rover North America technical literature system.

ACTION REQUIRED

Upon customer complaint for the symptoms outlined, perform the specified repairs.
