Maintenance After Off-Road Driving - Jeep Commander Owner's Manual

To prevent dirt and water from entering the transmission
after checking or replenishing fluid, make certain that the
dipstick cap is properly reseated. It is normal for the
dipstick cap to spring back slightly from its fully seated
position, as long as its seal remains engaged in the
dipstick tube.

Maintenance After Off-Road Driving

After extended operation in mud, sand or water, or
similar dirty conditions, have your brake discs, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
After driving off-road, completely inspect the underbody
of your vehicle. Check the tires, body structure, steering,
suspension and exhaust system for damage. Check

threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
Service Manual. Also check for accumulations of vegeta-
tion or brush that could become a fire hazard, or conceal
damage to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants, and lubricate body compo-
nents, all driveline joints and steering linkage more
often than in normal service, to prevent excessive
wear.
