Rear Axle And 4x4 Front Driving Axle Fluid Level
For models with 9.25 in Front Axles and 11.5 in Rear
Axles, refer to “Fluids, Lubricants, and Genuine Parts” in
this section for the correct fluid type. 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.
When checking the fluid level (4500/5500 only), the
vehicle should be in a level position. The fluid level
should be 1/4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the
fill hole on the front axle. The fluid level should be level
with the bottom of the fill hole on the rear axle.
Drain And Refill
On 4500/5500 vehicles, remove the lower bolt to drain
the axle fluid.
Refer to the “Maintenance Schedule” in Section 8 of this
manual for the proper maintenance intervals.
