chassis components for damaged, loose, or
missing parts or signs of wear at least once
ayear.
Inspect power steering for proper
attachment, connections, binding, leaks,

axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
liftgate hinges, and the steel fuel door hinges,

water to flush any corrosive materials from the
underbody. Take care to thoroughly clean any
areas where mud and other debris can collect.
Do not directly power wash the transfer case
and/or front/rear axle output seals. High
pressure water can overcome the seals and
contaminate the fluid. Contaminated fluid will
decrease the life of the transfer case and/or
axles and should be replaced.
