E. If necessary, remove nuts and flat washers and install tapered dowels, lock washers and stud nuts. Tighten to
the correct torque.
F. Connect universal at pinion shaft.
G. Install axle shafts.
Preparation For Storage.
In the event the carrier is a spare and may not be immediately installed, all gears and bearings should be thoroughly
oiled and the carrier placed in a dustproof container.
LUBRICATION.
Proper lubrication of the drive units is extremely important. Our "Standard" recommended lubricant is Rockwell-Standard
Specification 0-76, 0-76-A, 0-76-B or 0-76-D SAE 140 viscosity, multipurpose gear lubricant. Unusual operating
conditions such as extremes in climatic temperatures may require lubricants of "Optional" viscosities. However,
experience has shown that the use of an SAE 140 viscosity grade lubricant will result in longer gear life. Refer to Field
Maintenance Manual No. 1, "Lubrication", for detailed information.
Since Rockwell-Standard lubricant specifications are periodically revised, always refer to Field Maintenance Manual No.
1 for current complete lubricant specifications and applications.
A. Fill axle housing to the correct level with specified lubricant.
B. Lubricate universal joint.
C. Jack up both rear wheels and operate vehicle in high transmission gear at approximately 25 to 30 miles per hour
for five minutes to assure satisfactory lubrication of all parts of the carrier assembly.
Do not operate with one wheel jacked up. Operation in this manner will result in overheating the differential
spider with resultant galling or shearing of the spider pins.
Both wheel brakes should be free to allow both wheels to rotate at approximately the same speed.
New and Reconditioned Axle Service.
The original rear axle lubricant should be drained at the end of the drive-away or before the maximum of 3,000 miles
prior to placing the vehicle in regular service. Drain the lubricant initially used in the assembly following reconditioning at
the same interval. Completely drain the lubricant while the unit is warm.
Fill axle housings to bottom of level hole with specified lubricant with the vehicle level.
Regular Axle Service.
Refer to Field Maintenance Manual No. 1, "Lubrication", for recommended service interval.
