Rear Axle Breather Extension
AFFECTED VEHICLE RANGE:
Discovery Series II (LT)
Up to 2A755880
SITUATION:
WATER CONTAMINATION IN AXLE OIL
Constant water spray or wading may result in ingress of water through the rear axle breather tube, contaminating the axle oil. Rear axle oil may be
observed to be pale in color when checking oil levels at service intervals. This indicates that the rear axle oil is contaminated with water.
RESOLUTION:
INSTALLATION OF ALTERNATE BREATHER HOSE
Vehicles that are frequently waded or driven in extremely wet conditions and have verified axle oil contamination should have the revised rear axle
breather components installed. The new parts permit relocation of the breather vent to a high point in the body structure. Follow the instructions in this
TIB for installation.
