2019 Ram 4500 Chassis Cab torque

TECHNICAL SPECIFICATIONS 477
Torque Specifications
**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
NOTE:
Dual wheels are flat mounted, center piloted. The lug nuts
are a two-piece assembly. When the tires are being rotated or
replaced, clean these lug nuts and add two drops of oil at the
interface between the hex and the washer. Ensure that the
socket is fully engaged on the lug nut/bolt (do not insert it
half way). Oil Interface Location
Do not oil wheel studs. For chrome wheels, do not substitute
with chrome plated wheel nuts.

Wheel Mounting Surface
Retighten the wheel nuts in the same sequence to the torques
listed in the table. Go through the sequence a second time to
verify that specific torque has been achieved. Retighten to
specifications after 25 miles (40 km) and check the lug nut/
bolt torque to be sure that all the lug nuts/bolts are properly
seated against the wheel. 8/10 Lug Nuts/Bolts Torque Patterns
It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to specifi -
cations at each lubrication interval.
All wheel nuts should be tightened occasionally to eliminate
the possibility of wheel studs being sheared or the bolt holes
in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the wheel.

2 — 8 Bolt Pattern

TECHNICAL SPECIFICATIONS 479
The wheel nuts should then be tightened to recommended
torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut
opposite to the wheel nut just previously tightened until
final torque is achieved.
FUEL REQUIREMENTS
6.4L Engine
Do not use E-85 flex fuel or ethanol blends greater than 15%
in this engine.This engines is designed to meet all emissions regu -
lations and provide satisfactory fuel economy and
performance when using high quality unleaded
gasoline having a posted octane number range of 87 to 89 as
specified by the (R+M)/2 method. The use of 89 octane
“Plus” gasoline is recommended for optimum performance
and fuel economy. While operating on gasoline with an octane number of 87,
hearing a light knocking sound from the engine is not a cause
for concern. However, if the engine is heard making a heavy
knocking sound, see your dealer immediately. Use of gaso
-
line with an octane number lower than 87 can cause engine
failure and may void or not be covered by the New Vehicle
Limited Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before considering
service for the vehicle.
Reformulated Gasoline
Many areas of the country require the use of cleaner burning
gasoline referred to as “Reformulated Gasoline”. Reformu-
lated gasoline contains oxygenates and are specifically
blended to reduce vehicle emissions and improve air quality.
The use of reformulated gasoline is recommended. Properly
blended reformulated gasoline will provide improved
performance and durability of engine and fuel system
components.
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.
