6. Install chain fall or come-a-long to the loop on the
body just behind the hoist brackets. Attach the other
end of the lifting device to the eye previously installed
in the differential assembly.
7. Lift the differential assembly and carefully position it
on the studs of the banjo housing.
8. Secure the differential assembly to the banjo with
the self locking nuts removed at removal. Tighten the
nuts evenly to a torque of 380 Nm (280 lbf ft).
9. Replace the rear driveline, aligning marks made
during disassembly. Refer to Section 130-0020, REAR
DRIVELINE.
10. Install the axle shafts, then replace and secure the
driving flange cover to the wheels. Refer to Section
160-0030, AXLE GROUP.
11. Fill the drive axle, planetary reservoirs and
differential with the proper grade and quantity of
lubricant specified in Section 300-0020,LUBRICATION
SYSTEM.
MAINTENANCE
Periodic Inspection
Inspect regularly the flange yoke mounting bolts,
pinion shaft nut, pinion cage and seal retainer bolts,
and differential stud nuts for tightness. Tighten the
stud nuts and flange bolts weekly until they 'set' or
show that they no longer need tightening. Keep the
nuts tight to reduce the possibility of differential or
driveline failure due to excessive vibration or wear.

Replace any mounting studs which have become
SM - 2420
stripped or broken.
LOCTITE
SEALANT
Jack up the drive axle to 'test run' the differential and
listen for noises which may indicate the need for
adjustment or replacement of worn parts. When doing
this, lift BOTH wheels off the ground. Both wheel
brakes should be free to allow both wheels to rotate at
approximately the same speed.
Note: Do not operate with only one wheel jacked up.
Excessive operation in this manner will overheat the
differential spider and cause galling or shearing of the
spider trunnions and bearings.
If the differential is excessively noisy, it should be
removed from the banjo and disassembled for
inspection.
Lubrication
The differential is splash lubricated with an extreme
pressure lubricant. The fill level plug is located in the
centre rear of the banjo housing.
The differential should be checked and periodically
drained and filled to the bottom of the fill-level hole, or
to no more than 13 mm (0.5 in) below the fill level, with
new lubricant as recommended. Refer to Section
300-0020, LUBRICATION SYSTEM. When the
lubricant is drained, remove any chips of steel
particles that may be attached to the magnetic drain
plug located in the bottom of the banjo housing.
After draining and refilling an axle, the planetary
gearing should be checked after 10 hours of operation.
1. Check the level in planetaries at oil level plug. If the
oil level is low, add oil. This check point is a minimum
check point only. If the oil level is above the check
point, do not drain off oil.
2. Add oil if needed. The oil level is correct when oil
flows from the lube level check plug in the banjo.
These checks should be made every 10 hours until oil
level in the differential is maintained.
SPECIAL TOOLS
The spider bearing spreader tool can be fabricated as
shown in Fig. 19. Refer to Section 300-0070,
SERVICE TOOLS for part numbers of measuring tools
referenced in this section and general service tools
and adhesives required. These tools and adhesives
are available from your dealer.
