Allwheel drive only: Transfer case fluid change
(severe service) for vehicles mainly driven when
frequently towing a trailer, or used for taxi, police,
or delivery service. Check vent hose at transfer
case for kinks and proper installation. Check to be
sure vent hose is unobstructed, clear, and free of
debris. During any maintenance, if a power washer
is used to clean mud and dirt from the underbody,
care should be taken to not directly spray the
transfer case output seals. High pressure water
can overcome the seals and contaminate the
transfer case fluid. Contaminated fluid will
decrease the life of the transfer case and
should be replaced.
