Draw out live axle shaft from axle housing.
NOTE:
At this time, lower kingpin bearing sometimes
falls off. So remove bearing while pulling off
knuckle gradually.

At differential housing, disconnect propeller
shaft by removing bolts securing flange yoke to
companion flange. Remove 8 bolts holding fast
differential carrier case to housing, and take
down carrier assembly.
For Rear Differential
After taking down rear wheels, remove brake
drums by using special tools.
NOTE:
Before removing brake drum, check to ensure
that parking brake lever is not pulled up.
To increase clearance between brake shoe and
brake drum, remove parking brake shoe lever

Disconnect brake pipe from wheel cylinder.
Have a small plug ready for use when disconnect-
ing pipe. As pipe comes off the wheel cylinder,
plug the pipe to prevent brake fluid from
leaking out.
And remove 4 brake backing plate securing
bolts.

Using special tools indicated below, draw out
each axle shaft with brake backing plate.
Disconnect propeller shaft as in the case of front
axle, and detach and take down differential

Side Bearings Caps
When putting on side bearing caps, be sure to
discriminate the right-hand cap from the left-
hand one by referring to match marks scribed
at the time of disassembly.
Then, after carrying out “Bevel gear backlash
adjustment” as described on p. 16-10 torque cap
bolts to specification.

Reverse removal procedure for installation,
noting the following.
Differential
Before installing differential ass’y to axle hous-
ing, clean mating surfaces of differential carrier
and housing and apply sealant to them.

this manual.
Differential Gear Oil
Refill differential housing with new specified
oil. Refer to “MAINTENANCE SERVICE” in
this section for refill.
Brake Circuit Air Purging
If brake pipe (right & left) was disconnected
from wheel cylinder as in Fig. 16-9-2, make sure
to purge air out of brake circuit. Refer to
section 19. BRAKES for “air purging" operation.
Then check to ensure that joint seam of pipe is
free from oil leak.

NOTE:
l All suspension fasteners are an important attaching part in that it could affect the
performance of vital parts and systems, and/or could result in major repair expense.
They must be replaced with one of the same part number or with an equivalent part if
replacement becomes necessary. Do not use a replacement part of lesser quality or
substitute design. Torque values must be used as specified during reassembly to assure
proper retention of this part.
l Never attempt to heat, quench or straighten any suspension part. Replace it with a new
part, or damage to the part may result.
l The leaf spring number or shape shown in this manual may differ from the car being
actually serviced, depending on specification.

17-1. FRONT SUSPENSION
GENERAL DESCRIPTION
The front suspension consists of the double-acting shock absorbers, stabilizer bar, semi-elliptical leaf
springs, axle housing, etc. as shown below.
The Barfield universal joints are used in the front axle to enable the axle shafts to drive the front wheels
while allowing the wheels to be steered. This type of joint provides for a larger steering angle range and,
what is more important, constant-velocity drive to the wheel.
If a single two-yoke (or Hooke’s) universal joint is used to connect the axle shaft to the wheel on each
side of the front end, the wheels will run with the same speed, but not with the same constant velocity, as
that of the axle shafts when the wheels are turned around their kingpins for steering action. The Barfield
joint transmits drive without varying the angular velocity of drive.
The Barfield joint is enclosed by the knuckle, which is shaped integral with the knuckle arm, and has a
two-piece kingpin, namely, upper and lower kingpins.
The end of the dead axle sleeve is in the shape of dish. This dish is rotatably fitted into the knuckle
structure to form a flexible connection, the sliding clearance between the two being sealed with a felt
packing (against road dust and mud) and also with an oil seal (against the oil inside). The upper and lower
kingpins, bolted to the knuckle extend into the knuckle and, inside, are held by the dish-like inner case
through tapered roller bearings.

BARFIELD JOINT CONSTRUCTION AND OPERATION
The major parts of the Barfield joint are the outer race (integral with wheel spindle, to which the wheel
disc is splined), inner race (splined to the live axle shaft), six steel balls disposed between the two races,
and cage (holding the steel balls in a single row lying in a plane).
Spindle shaft
IInner raceSteel ball
The balls are fitted in two groups of raceways; one group is on the outer race and the other group on the
inner race. Each ball is in its own raceways as if it were locked between the two races in the direction of
rotation. The outer race with its wheel spindle is capable of angling and, when it so angles with respect to
the axis of axle shaft, the row of steel balls angles just half as much, that is, the plane including this row
tilts by an angle equal to one-half of the spindle angle. This relationship is illustrated in Fig. 17-1-4.

REMOVAL
Shock Absorber
The shock absorber is non-adjustable, non-
refillable, and cannot be disassembled.
The only service the shock absorber requires is
replacement when it has lost its resistance, is
damaged, or leaking fluid.

2. Loosen lower and upper mounting nuts and
remove shock absorber.

Leaf Spring
1. Raise car. In this operation, garage jack or
hoist must not be positioned against front

2. Remove front wheel.
3. Remove stabilizer bolt.
4. Remove U-bolt nuts.
5. Remove shackle nuts and leaf spring nut.
NOTE:
Removal of leaf spring causes axle housing to
hang. Support it with safety stand to prevent it
from damaging universal joint of propeller shaft
and others.
