GENUINE SPICER SER VICE PARTS
Should an axle assembly require replacement component
parts, it is recommended that Spicer Heavy Axle Service
Parts be used. Spicer Heavy Axle Service Parts are
manufactured under the same rigid specification as are
original equipment axle components. This assures the
customer who uses genuine Spicer service parts, maximum reliability for a Spicer Heavy Axle assembly. They
may be obtained through your vehicle manufacturer.
The use of non-original Spicer service parts may cause
premature component failure and may void the warranty.
The items included in this book are currently being offered
as service parts at the time of printing. The part numbers
and illustrations are provided specifically for reference
purposes only. Therefore, Spicer reserves the right to
update this manual without notice or liability.
i
All axle assemblies are identified with two tags. One
located on the differential carrier, and the other located
on the right hand side of the axle housing.
The differential carrier tag contains the following:
Dana part number, julian date code, and ratio. Optional
items include customer part number, line set number, and
the last six digits of the vehicle serial number.

AXLE LUBRICANT RECOMMENDATIONS
To ensure proper lubrication and operating temperature,
correct lubricants and lubricant levels must be obtained.
RECOMMENDED LUBRICANTS
Mineral or Synthetic based hypoid gear lubricants that
meet or exceed military specification MIL-L-2105D, and
API service classification GL-5, are the minimum requirements for use in Spicer Medium and Heavy Duty Drive
Axles.
The table below indicates which SAE viscosities are
recommended for various temperature ranges the vehicle
will encounter.
Ambient Air Temperature
APPLICATION
On Highway 100,000 1 Year 250,000 3 Year
* Severe Service
and 50,000 1 Year 100,000 1 Year
On-Off Highway
PETROLEUM BASED SYNTHETIC BASED**
MILES INTERVAL MILES INTERVAL
*Severe service includes any applications operating at
or near maximum GVW or GCW ratings. This
includes normally wet or dusty environments, or
consistent heavy load and low speed applications.
** Includes Semi-Synthetic blends that meet
MIL-L-2105D specifications.
AFTER OVERHAUL OR CHANGE INTERVALS
Fill the axle assembly to the bottom of housing fill hole
as shown in the illustration below. It is recommended
that following an overhaul, each side of the axle be
jacked up seperately to approximately six inches and held
into position for one minute. This procedure will allow
adequate lubricant to flow into the wheel ends and help
eliminate the possibility of premature damage to wheel
bearings and seals. Lower the vehicle to the floor and
allow ten minutes for lube to return to normal level.
Check and refill assembly to bottom of fill hole to replace
the lubricant that was directed into the wheel ends.
SERVICE
Recommended lubricant change intervals are dependent
on the application and operating environment. The
following chart should be used to establish proper
change intervals.
SUBMERSION OR DEEP WATER FORDING
In the event the axle assembly should become
submerged in water, particularly if over the vent or
breather, it is recommended that the lubricant be
drained and all parts be inspected for water damage
and/or contamination. Reassemble the carrier to the
housing and refill with specifed gear lubricant.
NOTE: Lubricant close enough to the bottom of the fill hole to be seen or touched
is not sufficient. Lubricant must be level with the fill hole.

GENERAL PRECAUTIONS
READ THIS SECTION BEFORE STARTING
GENERAL AXLE DESCRIPTION
IMPORTANT
ANY SERVICE PROCEDURES
This manual covers maintenance and rebuild procedures for the Spicer F155-S and F170-S rear drive axle
assemblies.
The Spicer Heavy Duty Single Reduction rear drive axle
is a full floating axle assembly, with a hypoid gear carrier
assembly, using a High Strength Low Alloy (HSLA) steel
axle housing. The hypoid pinion is straddle mounted
with two tapered roller bearings behind the pinion teeth
for thrust and radial loads. A pilot bearing is located on
the nose of the pinion for radial load. The differential
itself uses four precision forged pinion mate gears, a
forged cross, and precision forged side gears.
Safety glasses should be worn
at all times when assembling
or disassembling axles.
Accordingly, anyone who uses a service procedure or
tool different than shown must insure that their safety,
and the vehicle's safety, will not be jeopardized by the
service method selected.
END YOKES AND FLANGES
CAUTION: Hammering on end yokes can close
in the bearing bores or misalign yoke lugs and result
in early failures of journal needle bearings or other
driveline components. Serious damage can also be
done internally to the ring and pinion set or pinion
bearings by hammering on external parts. End yokes
or companion flanges should be removed or installed
using the recommended methods outlined in this
manual.
SAFTEY PRECAUTIONS
Proper service and repair of vehicle components is
important to the safe and reliable operation of all motor
vehicles. This applies particularly to driving axles such as
the ones described in this manual. The procedures
recommended and described in this manual are tested,
effective methods for performing service operations.
Follow each procedure closely, making use of both the
text and illustrations. Some of these service procedures
show the use of certain tools designed specifically for
the operation being performed. They are shown as a
preferred means of performing the operation. It is not
practical to anticipate and advise the service trade of all
possible alternative methods, and of all possible hazardous consequences that could occur.
CLEANLINESS
Axle components should be steam cleaned prior to
removal from the vehicle. Dirt is abrasive and will cause
premature wear of otherwise serviceable parts.
Service personnel should use a wash tank for thorough
cleaning of parts just prior to reassembly.
CAUTION
BRAKE LININGS CONTAIN NON-ASBESTOS FIBERS
BREATHING BRAKE DUST MAY BE HAZARDOUS TO YOUR HEALTH AND
MAY CAUSE SERIOUS RESPIRATORY OR OTHER BODILY HARM.
AVOID CREATING DUST
DO NOT REMOVE BRAKE DRUM WITHOUT PROPER PROTECTIVE EQUIPMENT.
DO NOT WORK ON LININGS WITHOUT PROPER PROTECTIVE EQUIPMENT.
DO NOT REPLACE LININGS WITHOUT PROPER PROTECTIVE EQUIPMENT.
DO NOT ATTEMPT TO SAND, GRIND, CHISEL, FILE, HAMMER OR ALTER BRAKE
LININGS IN ANY MANNER WITHOUT PROPER PROTECTIVE EQUIPMENT.
FOLLOW 0.S.H.A. STANDARDS FOR PROPER PROTECTIVE DEVICES TO BE USED
WHEN WORKING WITH BRAKE MATERIALS.

REMOVAL OF DIFFERENTIAL
CARRIER FROM AXLE HOUSING
NOTE: Steam clean axle assembly.
1. Block wheels.
2. Remove axle housing drain plug and drain lubricant.
3. Disconnect drive shafts at the rear U-joint.
NOTE: If end yoke and/or seal is to be replaced,
loosen yoke nut at this time.
4. Remove axle shaft flange nuts.
5. Hold a large brass drift or a brass hammer against
the center of the axle shaft flange. Strike the drift
with sharp blows from a large hammer or sledge
until the axle shaft separates from the hub.
CAUTION: Do not strike the flange directly
with a steel hammer or sledge. This may crack and
splinter material, possibly causing serious or fatal
injury. Do not pry or chisel axle flange away from
hub or damage to sealing surfaces could occur.
6. Remove axle shafts.
7.Support the differential carrier assembly on a roller
jack. Secure as necessary to prevent it from
falling off the jack when removed from the housing.
8. Use a breaker bar to loosen the differential carrier-
to-housing mounting bolts. Remove all bolts except
top two. These two bolts will prevent the carrier
assembly from falling.
9. Separate differential carrier from the housing. Be
certain carrier is balanced properly on jack, and
remove top two carrier-to-housing mounting bolts.
Remove differential carrier assembly from the axle
housing.
Mount carrier assembly in a suitable rebuild stand.
(Refer to Recommended Service Tools, pg. 22).

REMOVAL OF DIFFERENTIAL FROM CARRIER
1. Remove adjusting ring locks from bearing caps.
2. Match mark one differential bearing cap and leg withcenter punch or chisel for correct reassembly. See
Figure 1.
