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

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.
