151. GENERAL DESCRIPTION
These automobiles, covered in this manual are four-wheel drive machines and, as such, use three propeller
shafts designated as No. 1, No. 2 and No. 3.
No, 1 propeller shaft transmits drive from the transmission to the transfer gear box. No. 2 shaft and No. 3
shaft extend from the transfer gear box, the former driving the front axle and the latter the rear axle.
The cross spider in each universal joint is fitted with four needle roller bearings.

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.
16-6. INSTALLATION
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.

Front Axle Shaft and Steering Knuckle
For installation them, refer to “Front Suspen-
sion Installation” in SECTION 17 of this manual.
Rear Brake Drum
For installation of rear brake drum, refer to
“Rear Brake Installation” in SECTION 19 of
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.

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.
