Starting and operating

After Driving Off-Road

~1min read

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 specified 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.

• 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.
