After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage. That way you can get any
problems taken care of right away and have your vehicle
ready when you need it.
• Completely inspect the underbody of your vehicle. Check
tires, body structure, steering, suspension, and exhaust
system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering, and suspension.
Retighten them, if required, and torque to the values spec-
ified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.
NOTE:
Inspect the clutch vent holes in the manual transmission bell
housing for mud and debris and clean as required.
WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might not
have full braking power when you need it to prevent a
collision. If you have been operating your vehicle in
dirty conditions, get your brakes checked and cleaned as
necessary.
• If you experience unusual vibration after driving in mud,
slush or similar conditions, check the wheels for impacted
material. Impacted material can cause a wheel imbalance
and freeing the wheels of it will correct the situation.
