c. Axle Removal
The front and rear axle assemblies differ in that the front
axle assembly is equipped with a parking brake
mechanism and a 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 Tags.”)
3. Unlock and open the engine compartment cover.
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.
5. Models 10042 and 10054, Front Axle Only:
Remove outrigger assembly. Refer to Section 5.3.6,
a. “Outrigger Removal (10042, 10054 Only).”
6. If the axle will be disassembled after removal, place
a suitable receptacle under the axle drain plug (1).
Remove the drain plug and allow the axle oil to drain
into the receptacle. Transfer the used axle oil into a
suitable covered container, and label the container
as “Used Oil.” Dispose of used oil at an approved
recycling facility.
7. Label, disconnect and cap the steering and brake
lines at the axle. Wipe up any spilled oil.
8. Block the front and rear of both tires on the axle that
is not being removed. Ensure that the vehicle will
remain in place during axle removal before
proceeding.
9. Raise the vehicle using a suitable jack or hoist.
Place suitable supports under both sides of the
frame and lower the vehicle onto the supports.
Ensure that the vehicle will remain in place during
axle removal.
10. Support the axle that is being removed with a suitable
jack, hoist or overhead crane and sling. DO NOT
raise the axle or the vehicle.
11. Mark and remove both wheel and tire assemblies
from the axle that is being removed. (Refer to
Section 5.5.1, “Removing Wheel and Tire Assembly
from Vehicle.”)
Note: The wheel and tire assemblies must be re-installed
later with the directional tread pattern “arrows” facing in
the direction of forward travel.
12. Remove the drive shaft assemblies (2-Front or 3-Rear).
(Refer to Section 5.4.3, “Drive Shaft Removal.”)
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.
