.Four‐wheel drive only: Transfer case fluid change
(normal 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.
