"All-Purpose" Gear Lubricant-
Gear lubricants that will satisfactorily lubricate both passenger
car and truck hypoid rear axles, have been developed. These
lubricants are known as "All-Purpose" Gear Lubricants.
"All-Purpose" Gear Lubricants may also be used in passenger
car and truck transmission, steering gears, and in universal joints
requiring a fluid lubricant.
" All-Purpose" Gear Lubricants must be manufactured under
carefully controlled conditions and the Lubricant Manufacturer
must be responsible for the satisfactory performance of his
product. His reputation is your best indication of quality.
Lubricant Additions-
The lubricant
level in the housing should be checked periodically.
It is recommended that any additions, required to bring up
the lubricant level, qe made using the same type of lubricant as
in the housing.
Lubricant Changes-While
seasonal
changes of the lubricant are not required, it is recommended that
you have the housing drained and refilled with the recommended
lubricant at least twice a year, or every 6,000 to 10,000 miles.
CAUTION, Use a light
flu~ing
oil to
flu~
out the hausings when drain-
ing. Do not use water, steam, kerosene, gasoline, alcohol, etc.
UNIVERSAL JOINT
The universal joint receives its lubrication from the
transmission.
STEERING GEAR

lubricant. Seasonal change of this lubricant is unnecessary and
