set from service stock. Inspect the housing vent;
a closed vent will cause pinion seal or axle oil
seal failure. The vent is a small drilled hole,
located on a horizontal center line at the rear
side of the left axle tube, adjacent to the spring
mounting.
REAR AXLE INSTALLATION
"Hornet" and "Wasp" Series
Install the propeller shaft torque tube and truss
rods on the rear axle. The propeller shaft
companion flange bolts should be tightened 30-35
foot pounds torque on the "Hornet" Series and the
Hydra-Matic equipped "Wasp"
The "Wasp" Series equipped with standard and
overdrive transmissions has the "slip" type
coupling. The propeller shaft with the coupling
can now be installed on the pinion shaft.
Lubricate the ground surface on the coupling and
the torque tube rear oil seal with rear axle
lubricant. Do not crimp the lip of the oil seal.
The torque tube oil seal should seal and contact
the coupling on the ground surface of the coupling.
Slide the propeller shaft front universal joint
onto the transmission main shaft, raise the rear
axle into position, and reassemble the torque
tube to the transmission.
Install the rear springs, brake line, hand brake
cables, and bleed the brake lines.
"Rambler" Series 100" Wheelbase
and 108" With Hydra-Matic
Transmission
Slide the propeller shaft onto the transmission
main shaft until it is bottomed on the shaft. Then
mark the front universal joint at the rear of the
transmission oil seal and again remove the
propeller shaft.
Install the propeller shaft on the rear axle
pinion, and install the rear springs on the axle
tubes.
The axle assembly is then installed on the car.
Install the brake lines, shock absorbers,
springs, brake cables, and the wheel hubs.
With the body supported at the body side sills,
permit the rear axle assembly to hang freely
with the shock absorbers fully extended. Adjust
the propeller shaft so the scribe mark is %2"
to the rear of the transmission oil seal.
Tighten the coupling to 300 foot pounds torque.
Bleed the brake lines.
108" Wheelbase With Standard and
Overdrive Transmission
Install the rear springs on the axle tubes.
Install the axle assembly on the car and connect
the rear propeller shaft to the pinion shaft.
Then install the brake lines, shock absorbers,
springs, brake cables, and wheel hubs.
Bleed the brake lines.
Final Inspection
The rear axle should then be road tested to
determine if all the adjustments and correc-
tions are satisfactory.
AXLE DIAGNOSIS
Test No. 1
With the engine warmed up and the overdrive
locked in conventional gear position, drive at
ten miles per hour. Listen carefully and keep
driving at this speed until thoroughly familiar
with all car noises.
Now gradually increase the speed until the car
reaches forty-five miles an hour. As the car is
gaining speed, notice any changes in the
running gear noises; notice the speed at which
each noise comes in and goes out.
Then release the accelerator, and without using
the brakes, allow the car to slow down. Again
make a note of every change in sound and the
speed at which each change takes place.
It will probably be found that every sound comes
in and leaves at the same speeds on both
acceleration and deceleration.
Test No. 2
Step the car up to fifty miles per hour, shift
into neutral, turn off the ignition, and allow
the car to coast until it comes to a stop.
Listen again to all the running noises. Notice
at very low speeds a low pitched sound will come
in; this is tire noise, not axle noise.
While making this test, note again all the
changes in running noise and the speeds at which
they come in and go out. Any of the noises noted
in Test No. 1 which also appear in Test No. 2
can be eliminated as axle noise because, on this
test, the axle is not under
