2020 Ram 1500 Differential fluids

SERVICING AND MAINTENANCE 515
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
The fluid level should be even with the bottom of the fill hole
(within 1/4 in (6.4 mm) of edge of hole) for the front axle and
rear axle.
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical Specifica-
tion” for further information.
NOTE:
The presence of water in the gear lubricant will result in
corrosion and possible failure of differential components.
Operation of the vehicle in water, as may be encountered in
some off-highway types of service, will require draining and
refilling the axle to avoid damage. Limited-Slip Differentials
Rear axles equipped with a Limited Slip Differential require
that 5 oz. (148 ml) Mopar Limited Slip Additive be added to
the gear lubricant. Refer to “Fluids And Lubricants” in
“Technical Specification” for further information. The
Mopar Limited Slip Additive should be added to the gear
lubricant whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
NOTE:
When refilling a limited slip differential axle which requires
a friction modification additive, the additive should be
added before the gear lubricant to ensure proper additive
fill.
Drain And Refill
Refer to the “Maintenance Plan” for the proper maintenance
intervals.
Transfer Case
Selection Of Lubricant
Use only the manufacturer's recommended fluid. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information.
