Axles, Drive Shafts, Wheels and Tires

CLEANING: Clean parts with machined or ground

surfaces (such as gears, bearings and shafts) with

emulsion cleaners or petroleum-based cleaners. DO

NOT steam clean internal components, and the interior of

the planetary hub and axle housing. Water can cause

corrosion of critical parts. Rust contamination in the

lubricant can cause gear and bearing failure. Remove old

gasket material from all surfaces.

DRYING: Use clean, lintless towels to dry components

after cleaning. DO NOT dry bearings by spinning them

with compressed air. This can damage mating surfaces

due to lack of lubrication. After drying, lightly coat

components with oil or a rust-preventive chemical to help

protect them from corrosion. If storing components for a

prolonged period, wrap them in wax paper.

PERIODIC OPERATION REQUIREMENT: Every two

weeks, drive the vehicle far enough to cause the drive-

train components to make several complete revolutions.

This will help assure that internal components receive

lubrication to minimize deterioration caused by

environmental factors such as high humidity.

SUBMERSION: If the vehicle has been exposed to water

deep enough to cover the hubs, disassemble the wheel

ends, and inspect for water damage and contamination.

If the carrier housing was submerged in water, and

especially if the water level was above the vent tube

(breather), drain the axle, and inspect internal parts for

water damage and contamination. Before assembling

and refilling the unit with the specified lubricant(s), clean,

examine and replace damaged parts as necessary.

Note: Use a suitable puller for bearing removal. Clean,

inspect and lubricate all bearings just prior to

reassembly. If replacement of a damaged bearing cup or

cone is necessary, replace the cup and cone as a set.

5.3.6 Axle Replacement

a. Removal

The front and rear axle assemblies differ in that the front

axle assembly is equipped with a parking brake

mechanism and limited-slip feature; the rear axle has

neither. The following steps outline a typical axle removal

procedure, suitable for either the front or the rear axle

assembly.

Cleanliness is extremely important. Before attempting to

remove the axle, thoroughly clean the vehicle. Avoid

spraying water or cleaning solution on the stabilizer

solenoids and other electrical components. If using a

steam cleaner, seal all openings before steam cleaning.

IMPORTANT: Clear the work area of all debris,

unnecessary personnel, etc. Allow sufficient space to

raise the vehicle and to remove the axle.

1. Park the vehicle on a firm, level surface, level the

vehicle, ground the attachment, place the travel select

lever in the (N) NEUTRAL position, place the neutral

lock lever in the (N) NEUTRAL LOCK position, engage

the parking brake switch, straighten all wheels and

shut the engine OFF.

2. Place an Accident Prevention Tag on both the

ignition key switch and steering wheel, stating that

the vehicle should not be operated. (Refer to Section

1.5, “Accident Prevention Tag Usage.”)

3. Unlock and open the rear door. Allow the engine,

transmission and hydraulic fluid to cool.

4. Disconnect the battery negative (-) cable at the

battery negative (-) terminal, to prevent the engine

from starting accidentally.

WARNING: An improperly supported

vehicle can fall, causing death or severe

personal injury. Safely raise and adequately

support the vehicle, so that it will remain stable

and in place before attempting to remove an axle.

WARNING: Hot hydraulic fluid can cause

severe burns. Wait for the hydraulic fluid to cool

before servicing any hydraulic component.

WARNING: Relieve hydraulic pressure

before servicing any hydraulic component.

Escaping hydraulic fluid under pressure can

penetrate the skin, causing death or serious

injury.
