1.
Rear A
xle.
Check lubricant level twice
a year, preferably in the Spring and Fall. When
checking lubricant level, clean around filler
plug before removal and use care to avoid in-
troducing dirt and abrasive material into the
lubricant.
If
level is low, fill axle housing to
filler plug opening with approved lubricant as
specified in paragraph
1-9.
2. Steering
Gear.
Check level of lubricant
in housing. Add lubricant specified below to
level of filler opening. Do not use pressure fit-
.
ting in filler opening, as this will force lubri-
cant up the steering column.
If
lubricant level is very low, check for ex-
cessive leakage at pitman shaft seal in lower
end of
housing.
The steering gear is filled at the factory with
a special all-season gear lubricant. Seasonal
change of lubricant is unnecessary.
When necessary to add lubricant or to fill a
steering gear that has been rebuilt, use
"Sagi-
naw All-Season Steering Gear Lubricant". This
lubricant is marketed through United Motors
Service in 5, 10
and 25 pound
containers.

"Saginaw
All-Season Steering
Gear Lubri-
cant" is not av
ailable, "
