THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 21-05-98 DATED
MARCH 20, 1998 WHICH SHOULD BE REMOVED FROM YOUR FILES AND NOTED IN
THE BOUND TECHNICAL SERVICE BULLETIN BOOK, PUBLICATION NUMBER 81-

SUBJECT:
Auxiliary Differential Vent

OVERVIEW:
This bulletin involves installing an auxiliary differential vent and changing the differential fluid.

MODELS:
1993 -**2000** (LH) Concorde/Intrepid/LHS/New Yorker/Vision/300M
1997 -**2000** (PR) Prowler

DISCUSSION:
An auxiliary vent tube assembly has been released for service to provide improved differential case venting. In cold climate areas, under certain driving
conditions, pressure can build up in the differential case forcing fluid out through the primary vent tube at the top of the differential. Fluid can collect on
the top of the differential case and or drip to the ground.

SYMPTOM/CONDITION:
Differential fluid buildup near the differential vent and/or dripping on the ground.

DIAGNOSIS:
Inspect the top of the differential for fluid. Fluid may drip down the side to the ground.

PARTS REQUIRED:
