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.

COMPONENT PARTS REPLACEMENT

(Chevrolet, Cheveile, Chevy II and Camaro)

AXLE ASSEMBLY

Removal

1.
Raise vehicle to a height that will permit axle as-

sembly to hang freely and position supports under

both frame side rails.

2.
Disconnect wheel cylinder inlet lines. Disconnect and

remove brake hose and brake line retaining bracket

by removing retaining bolt from carrier cover.

3.
Loosen parking brake equalizer adjusting nut and

disconnect both rear cables at frame bracket and at

control arms. See Section 5 for detail of parking

brake cable removal.

4.
Remove two trunnion bearing "U" bolts from the

rear yoke and separate rear universal joint. Wire

propeller shaft to frame side rail and tape trunnion

bearing cups.

5. Support arid secure axle assembly with an adjustable

lifting device. On Chevrolet and Cheveile models,

loosen upper and lower control arm attaching bolts

at axle housing. (On Chevrolet models, disconnect

tie rod at axle bracket.)

6. Disconnect shock absorbers at axle brackets. Refer

to Shock Absorber Removal procedures outlined in

this section.

7. On Chevrolet and Cheveile models, lower axle as-

sembly until suspension reaches end of travel, then

disconnect spring retainers and withdraw springs

from vehicle.

8. On Chevy II and Camaro models, remove four nuts

securing lower spring seat to axle housing, then

remove spring front eye bolts or spring attaching

bracket and swing spring to rear so that it does not

interfere with axle.

9. On Chevrolet and Cheveile models, disconnect upper

and lower control arm attaching bolts at axle housing*
10.
Lower axle assembly and remove from under vehicle.

Installation

1.
Place axle assembly under vehicle and raise into

position.

2.
On Chevrolet and Cheveile models, install, but do not

tighten, upper and lower control arm attaching bolts

at axle housing.

3.
On Chevrolet models, position coil springs in upper

seats so that end of spring is indexed in seat.

4.
On Chevrolet models, install lower end of spring on

axle bracket or control arm and secure by installing

retainer and bolt. Install lock washer and retainer

nut.

5. On Cheveile pry lower pigtail of spring over vertical

flange of the axle bracket spring seat.

6. On Chevy II and Camaro models, install spring seat

pads and swing springs up into spring seats on axle

housing, making sure upper seat pads are aligned in

axle housing bracket.

7. Install spring front eye bolt and tighten, then install

spring seat lower mounting bracket and retaining

nuts.

8. Raise axle assembly to allow shock absorber and tie

rod installation. Position shock absorber in axle

bracket. Torque nut as outlined in Shock Absorber

Installation procedures.

9. Install brake hose and brake line retaining bracket

to carrier and connect wheel cylinder inlet lines.

at control arm. Adjust parking brake and bleed

brakes as outlined in Section 5.

10.
Reassemble rear universal joint to companion flange.

11.

4.
Install brake components on flange and connect

hydraulic line to wheel cylinder inlet. See Section 5

for brake assembly procedure.

5. Install axle shaft, brake drum and wheel and tire

assembly.

6. Bleed and. adjust brakes as outlined in Section 5.

Installation

1.
Slide axle shaft into place.

CAUTION: Exercise care that splines on end

of shaft do not damage oil seal and that they

engage with splines of differential side gear/

2.
Install axle shaft "C" lock on button end of axle-

shaft and push shaft outward so that shaft lock seats

in counterbore of differential side gear.

3.
Position differential pinion shaft through case and

pinions, aligning hole in shaft with lock screw hole.

Install lock screw and torque to specifications.

4.
Using a new gasket, install carrier cover and torque

bolts to specifications.

CAUTION: Make sure both gasket surfaces on

carrier and cover are clean before installing

new gasket. Torque carrier cover bolts in a

crosswise pattern to ensure uniform draw on

cover gasket.

5. Fill axle with lubricant to a level even with bottom

of filler hole. See Section 0 for proper lubricant.

6. Install brake drum and wheel and tire assembly.

7. Lower vehicle and test operation of axle.

PINION FLANGE, DUST DEFLECTOR

AND/OR OIL SEAL

Replacement

1.
Raise rear of vehicle and place stand jacks under

frame side rails so that axle hangs freely to allow

sufficient working room.

2.
Check wheels for freedom of rotation.

3.
Separate rear universal joint, tape trunnion bearings

to joint, position propeller shaft to one side and tie

it to frame side rail.

4.
Using Tool J-5853 with Adapter J-5810 and a suitable

socket on the pinion flange nut, rotate the pinion

through several complete revolutions and record the

torque required to keep the pinion turning (fig. 82).

If flange is to be reused, mark pinion and flange for

reassembly in the same relative position.

5. Install Tool J-8614-1 on pinion flange and remove

pinion flange nut and washer (fig. 83). (Position
Fig. 82—Measuring Drive Pinion Bearing Preload

J-8614-1 on flange so that the four notches are

toward flange.) Discard nut and use a new one

upon reassembly.

6. Thread pilot end of Tool J-8614-3 into small O.D.

end of J-8614-2. Then with J-8614-1 installed as

in Step 4, insert J-8614-2 into J-8614-1 and turn

it 45 degrees to locked position. Remove flange by

turning J-8614-3 while holding J-8614-1 (fig. 84).

7. Pry old seal out of bore, using a screw driver or a

hammer and chisel.

8. Inspect pinion flange for smooth oil seal surface,

worn drive splines, damaged ears, and for smooth-

ness of bearing contact surface. Replace if

necessary.

9. If deflector requires replacement, remove by tapping

from flange, clean up stake points; install new de-

flector, and stake deflector at three new equally

spaced positions.

NOTE:
Staking operation must be performed

in such a manner that the seal operating surface

is not damaged.

flange oil seal with a lithium-base extreme pressure

lubricant, position seal in bore, then using Tools

J-21468 and J-9458, for light-duty axle and Tool
