‐
wheel 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.
