GENERAL DESCRIPTION
CHEVROLET, CHEVELLE, CHEVY
I! AND
CAMARO
The rear axle
(fig. 72) is a
semifloating, fabricated
construction type consisting
of a
cast carrier with large
bosses
on
each
end
into which
two
welded steel tubes
are fitted.
The
carrier contains
an
overhung hypoid
pinion
and
ring gear.
The
differential
is a
two pinion
arrangement.
The axle housing
is
made up
of
two steel welded tubes
pressed into
the
crossbore
of the
cast carrier
-
each
tube
is
puddle welded
at
three places
to the
carrier.
Welded-on brackets provide attachment points
for
Chevelle springs,; shock absorbers,
and
lower control
arms.
Chevrolet models have welded-on brackets
for
control arms,
tie
rod, and shock absorbers. The housing
on Chevy II and Camaro has welded brackets
for
mounting
lower spring
pad
and shock absorber.
A
welded flange
is
provided
for
brake flange plate attachment.
The overhung hypoid drive pinion
is
supported
by
two
preloaded tapered roller bearings.
The
pinion shaft
is
sealed
by
means
of a
molded, spring loaded, rubber seal.
The seal
is
mounted
on the
pinion shaft flange which
is
splined and bolted
to
the hypoid pinion shaft.
The hypoid ring gear
is
bolted
to a
one-piece differen-
tial case which
is
supported
by two
preloaded tapered
roller bearings.
CORVETTE
The Corvette rear axle
is of the
type where
the dif-
ferential carrier housing enclosing
the
differential
and
hypoid gears
is
supported
on a
crossmember mounted
to
the chassis frame.
The
differential
is
connected through
universal joints
to the
drive shafts
and
wheels
(fig. 73).
The internal components
of the
carrier
are of
conven-
tional design, incorporating
a
hypoid gear
set
with
an
overhung pinion supported
on two
pre-loaded, tapered
roller bearing assemblies,
and a
two-pinion differential
assembly supported
on
tapered roller bearings. Pinion
mounting distance adjustments
are
made through the
use
of shims,
as are the
differential bearing pre-load
and
backlash adjustments.
The
differential side gears drive
two splined yokes which
are
retained laterally
by
snap
rings located on the yoke splined end. The yokes
are
sup-
ported on caged needle bearings pressed into
the
carrier,
adjacent
to the
differential bearings.
A
lip seal, pressed
in outboard
of
the bearings, prevents
oil
leakage and dirt
entry.
The
carrier cover
is
bolted
to the
carrier and
provides accessibility
to the
internal parts.
The
cover
incorporates two integral, reinforced mounting pads which
serve
as the
carrier attaching point
to the
suspension
crossmember,
and an
attaching point
for the
spring
center section. The filler plug
is
located on the right side
of the cover near the bolting flange.
All service operations allow carrier removal without
removing
the
carrier cover. Cover removal
is
not nec-
essary
in any of the
service procedures except
in
the
case
of
complete carrier housing replacement,
as the
carrier and cover
are
serviced
as
an assembly.

MAINTENANCE AND ADJUSTMENTS
The lubricant level should be periodically checked and
maintained at level of filler plug with a warm axle. See
the lubrication section of this manual for lubricant
recommendations.
Lubricant Leaks
Lubricant leaks should be checked for at the pinion
flange oil seal, axle wheel bearing seals, lubricant-filler
plug, and carrier cover. Correction of these leaks con-
sists of replacing the defective seals or gaskets involved
as described in this section.
AXLE BOLTS AND WHEEL NUTS
From a safety standpoint, axle housing to rear spring
bolts,
wheel nuts and control arm attaching bolts should
be periodically inspected for secure installation.

REAR AXLE NOISE DIAGNOSIS
Mechanical failures of the rear axle are relatively
simple to locate and correct. Noise in a rear axle is a
little more difficult to diagnose and repair. One of the
most essential parts of rear axle service is proper
diagnosis.
Ail rear axles are noisy to a certain degree. The
action of transmitting the high engine torque through a
90° turn reducing propeller shaft speed produces noise
in rear axles. This point establishes the need for a line
between normal and abnormal or unacceptable axle
noises.
Slight axle noise heard only at a certain speed or under
remote conditions must be considered normal. Axle noise
tends to "peak" at varying speeds and the noise is in no
way indicative of trouble in the axle.
If noise is present in an objectionable form, loud or at
all speeds, an effort should be made to isolate the noise
as being in one particular unit of the vehicle. Axle noise
is often confused with other noises such as tire noise,
transmission noise, propeller shaft vibration and uni-
versal joint noise. Isolation of the noise as in any one
unit requires skill and experience. An attempt to elimini-
ate a slight noise may baffle even the best of diagnos-
ticians. Such practices as raising tire pressure to
eliminate tire noise, listening for the noise at varying
speeds and on drive, float and coast, and under proper
highway conditions, turning the steering wheel from left
to right to detect wheel bearing noise, will aid even the
beginner in detecting alleged axle noises. Axle noises
fall into two categories: gear noise and bearing noise.
GEAR NOISE
Abnormal gear noise can be recognized since it pro-
duces a cycling pitch and will be very pronounced in the
speed range at which it occurs, appearing under either
"drive," "float" or "coast" conditions. Gear noise
tends to peak in a narrow speed range or ranges, while
bearing noise will tend to remain constant in pitch. Ab-
normal gear noise is rare and usually originates from
the scoring of the ring gear and pinion teeth as a result
of insufficient or improper lubrication in new assemblies.
Side gears seldom give trouble as they are used only
when the rear wheels travel at different speeds.
BEARING NOISE
Defective bearings will always produce a whine that is
constant in pitch and varies with vehicle speed. This fact
will allow you to distinguish between bearing noise and
gear noise.
1.
Pinion bearing noise resulting from a bearing failure
can be identified by a constant rough sound. Pinion
bearings are rotating at a higher speed than differen-
tial side bearings or axle shaft bearings. This
particular noise can be picked up best by testing the
car on a smooth road (black top). However, care
should be taken not to confuse tire noise with bear-
ing or gear noise. If any doubt exists, tire treads
should be examined for irregularities that would
produce such noise.
2.
Wheel bearing noise may be confused with rear axle
noise. To differentiate between wheel bearings and
rear axle, drive the vehicle on a smooth road at
medium-low speed. With traffic permitting, turn
Fig.
74—Scored Hypoid Ring Gear
the vehicle sharply right and left. If noise is caused
by wheel bearings, it will increase in the turns be-
cause of the side loading. If noise cannot be isolated
to front or rear wheel bearings, inspection will be
necessary.
3.
Side bearings will produce a constant rough noise of
a slower nature than pinion bearings. Side bearing
noise will not fluctuate in the above wheel bearing
test.
Failure Analysis
The most common types of rear axle failures are
hypoid gear tooth scoring and fracture, differential gear
fracture. and/or differential bearing failure, and axle
shaft bearing failure.
Fig.
75-Cracked Hypoid Ring Gear
CHEVROLET CHASSIS SERVICE MANUAL
Page 220 of 659
REAR SUSPENSION AND DRIVE LINE 4-30
Fig.
76—Differential Gear Failure
Hypoid Gears
Hypoid gear tooth scoring (fig. 74) is caused generally
by improper break-in, incorrect lube, insufficient gear
backlash or improper 'ring/pinion gear alignment. The
scoring will progressively lead to complete erosion of
the gear tooth, or gear tooth pitting and eventual fracture
with possible attendant damage to bearings, if the initial
scoring condition is not diagnosed in time and corrected.
Hypoid gear scoring is easily recognized by its char-
acteristic loud whine in either drive, coast or under both
conditions. Another cause of hypoid tooth fracture (fig.
75) is extended overloading of the gear set which will
produce fatigue fracture, or shock loading which will
result in sudden failure.
Differential Gears
Common causes of differential gear failure are shock
loading, extended overloading leading to fatigue failure,
and overheating of gear thrust surfaces resulting from
excessive wheel spin and consequent lubrication break-
down. Overheating will lead to seizing of thrust surfaces
or tooth failure (fig. 76).
Bearings
• Failure of axle tapered roller bearings is due pri-
marily to excessive wear caused by long service or
foreign materials in the oil. The second most common
cause of bearing failure is too tight or too loose pre-
load adjustment leading to spalling and eventual failure.
This failure may also lead to hypoid gear scoring due to
the resultant misalignment of the hypoid gear set.
