ure 11. Drain the oil and replace with three pounds (or pints) of fresh oil
with season.
The wheel bearings are lubricated with wheel bearing grease. The bear-
ings should each be packed with one and one-half ounces of grease every
5,000 miles. In order to insert this grease the wheels and wheel bearing caps
must he removed.
The front axle is of the Elliott type, the center section being a drop
forging of high quality carbon steel. The axle has an "I" beam section
between the spring seats to give strength with light weight to sustain the
weight of the car. The axle ends—from the spring seats to the spindle pin
yoke—are elliptical in section, giving strength to resist both the load of the
car and the twisting action developed when the brakes are applied. This
forging is heat-treated for strength and elasticity to give maximum protec-
tion against distortion from load and shock.
The steering spindles, arms and pins are heat-treated molybdenum alloy
steel. The spindle pins are case-hardened to resist wear and are supported in
the axle by hardened steel bushings. The end thrust on the pin is carried by
five ball bearings running in a race machined directly in the end of the
spindle pin.
Each wheel is mounted on two taper roller bearings, while the tie rod end
sockets are each mounted on the steering arms with two annular thrust ball
bearings for rigid mounting and frictionless control.

Lubrication
An oil must be used that will with-
stand the pressures developed be-
tween the gear teeth and also flow
freely to enter the smaller clearances
and circulate through the passages to
the pinion bearings. These qualities
can be obtained in a heavy bodied
gear oil of S.A.E. 110 specification
for summer and S A.E. 90 for winter.
The oil should always be kept to
the level of the filler plug (A), Fig-
