d. Rear Wheef Bearing Seals
Greased and sealed rear wheel bearings are
used on all 60, 62, and Seventy-Five series cars.
The bearings are sealed on the outer side by a
rubber grease seal that is integral with the bear-
ing. The inner oil seal, however, can be serviced
separate from the bearing. The rear wheel bear-
ings require no adjustment or periodic lubrica-
tion. Sealing between the outer diameter of the
bearing and inner diameter of the axle housing is
accomplished by an O-ring seal that should be re-
placed whenever the axle shaft is removed. The
procedure for replacing this O-ring is described
in Section 7, Note 6d.
Rear wheel bearings on commercial chassis
are sealed on both sides by grease seals that are
lubricated by an initial grease packing. An addi-
tional inner shaft seal prevents differential lu-
bricant from entering the bearings and brake
assembly. Whenever a rear axle shaft oil seal is
removed, a new oil seal must be installed as ex-
plained in Section 7, Note 8.
6. Checking Standing Height
Before checking standing (spring) height, make
sure that trunk is empty, except for spare tire
and jack, and that there is a full tank of gasoline
as all specifications are based on this curb weight.
Normalize position of springs by working bumper
up and down; release bumper and permit car to
assume its normal position.
a. Front Springs
Measure distance from top of rear flange on
lower suspension arm to center of hole on frame
side rail, Fig. 4-21. Standing heights should be
equal on both sides of car within 3/8 inch. If
heights are unequal, low side may be adjusted by
addition of a shim between top of spring and
spring seat inside frame tower. Shims are avail-
able from factory Parts Warehouses. No more
than one shim per side should be used.
See Page 4-32 for specifications for each series.
