Front/Rear Axle Fluid - Jeep Gladiator 2020 Owner's Manual

WARNING! (Continued)
• To avoid contamination from foreign matter or mois-
ture, use only new brake fluid or fluid that has been in
a tightly closed container. Keep the master cylinder
reservoir cap secured at all times. Brake fluid in a open
container absorbs moisture from the air resulting in a
lower boiling point. This may cause it to boil unexpect-
edly during hard or prolonged braking, resulting in
sudden brake failure. This could result in a collision.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing the
brake fluid to catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should be taken to
avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contaminate the
brake fluid. Brake seal components could be damaged,
causing partial or complete brake failure. This could
result in a collision.
SERVICING AND MAINTENANCE

Front/Rear Axle Fluid

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.
Fluid Level Check
Lubricant should be approximately 1/8 inch (3 mm) below
the bottom edge of the oil fill hole.
NOTE:
Make sure that the vehicle is level and supported by the
axles.
Adding Fluid
Add lubricant only at the fill hole and only to the level spec-
ified above.
Selection Of Lubricant
Use only the manufacturer's recommended fluid. Refer to
"Fluids And Lubricants" in "Technical Specifications" for
further information.
