2018 DODGE DURANGO wheel torque

with all four wheels turning against engine compression
drag. This will permit you to control the vehicle speed and
direction.
When descending mountains or hills, repeated braking can
cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
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 sus-
pension. 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.
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.
364 STARTING AND OPERATING

CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.
8. Lower the vehicle by turning the jack screw counter- clockwise, and remove the jack and wheel blocks.
9. Finish tightening the lug nuts. Push down on the wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each nut has been tightened twice. Refer to “Torque Specifi-
cations” in “Technical Specifications” for proper lug nut
torque. If in doubt about the correct tightness, have
them checked with a torque wrench by an authorized
dealer or at a service station.
10. Push out the small center cap using the jack tool from inside the aluminum road wheel and position the
wheel behind the rear bumper with the protective plate
facing outward.
NOTE: The plastic plate will prevent the road wheel from
being scratched when sliding it under the vehicle.

13. Lower the jack to the fully closed position. Return thetools to the proper positions in the tool bag. Fold the
flap on the tool bag under the tools and roll the tools in
the bag underneath the others. Use the hook and loop
fasteners to secure the tool bag to the jack with the lug
wrench on the forward side of the jack. Expand the jack
on the bracket by turning the thumb screw clockwise
until it is tight to prevent rattles.
14. Reinstall the plastic plug into the floor of the cargo area. Roll up and store the Jack, Tool Kit and Tire
Changing Instructions. Reinstall the cover for the jack
in the rear storage bin.
15. Have the aluminum road wheel and tire repaired as soon as possible and properly secure the spare tire, jack
and tool kit.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped endof the nut toward the wheel. Lightly tighten the lug
nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the wheel nuts fully until the vehicle has
been lowered. Failure to follow this warning may
result in serious injury.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Refer to “Torque Specifications” in “Technical Specifica- tions” for proper lug nut torque.
5. After 25 miles (40 km), check the lug nut torque with a torque wrench to ensure that all lug nuts are properly
seated against the wheel.

BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake sys-
tems. If either of the two hydraulic systems loses normal
capability, the remaining system will still function. How-
ever, there will be some loss of overall braking effective-
ness. You may notice increased pedal travel during appli-
cation, greater pedal force required to slow or stop, and
potential activation of the Brake Warning Light. In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the brakes
will still function. However, the effort required to brake the
vehicle will be much greater than that required with the
power system operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure that
the wheel is properly mounted to the vehicle. Any time a
wheel has been removed and reinstalled on the vehicle, the
lug nuts/bolts should be torqued using a properly cali-
brated torque wrench using a high quality six sided (hex)
deep wall socket.

TECHNICAL SPECIFICATIONS 471

Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each
nut/bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it half
way).
NOTE:If in doubt about the correct tightness, have them
checked with a torque wrench by your authorized dealer or
service station. After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly seated against
the wheel.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may
result in personal injury.
