IN-CAR ADJUSTMENT AND REPAIR
REAR AXLE SHAFT, WHEEL
BEARING, AND OIL SEAL
REPLACEMENT
The rear axle shafts, wheel bear-
ings and oil seals can be replaced
without removing the axle assembly
from the car.
1. Remove the wheel and tire from
the brake drum.
2. Remove the Tinnerman nuts
that secure the brake drum to the
axle shaft flange, and then remove
the drum from the flange.
3. Working through the hole pro-
vided in the axle shaft flange, re-
move the nuts that secure the wheel
bearing retainer to the axle housing
(Fig. 2).
4. Pull the axle shaft assembly out
of the axle housing (Fig. 3). InstaJI
one nut to hold the brake backing
plate in place after the axle shaft
is removed.
5. Check the bearing for smooth
free rotation. Check the axle shaft
splines for burrs, wear or damage.
Replace worn or damaged parts.
6. If the rear wheel bearing is to
be replaced, loosen the inner r~tainer
ring by nicking it deeply with a cold
chisel in several places (Fig. 4). It
will then slide off easily.
7. Press the bearing from the axle
shaft with the tool shown in Fig. 5.
8. Inspect the machined surface
of the axle shaft and the axle hous-
ing for rough spots or other irregu-
larities which would affect the seal-
ing action of the oil seal. Carefu11y
remove any burrs or rough spots.
9. Lightly coat the wheel bearing
bores with baH joint grease.
10. Place the retainer plate on the
axle shaft, and press the wheel bear-
ing on the shaft with tool 4621-A as
shown in Fig. 6.

11. Press on a new wheel bearing
retainer ring with tool 4621-A. Do
not attempt to press on both the
wheel bearing and retainer ring
at the same time.
12. Whenever a rear axle shaft
is removed, the oil seal must be
replaced. Remove the seal with the
tool shown in Fig. 13.
13. Soak new seals in SAE 10 oil
for 1/2 hour before use. Install the
new seal with tool 4245-B as shown
in Fig. 14. Wipe a small amount of
an oil resistant sealer on the outer
edge of the seal before it is installed.
Do not put sealer on the sealing
lip. Install the seal with its sealing
tips toward the axle housing.
14. Place a new gasket on each
side of the brake backing plate,
and then carefully slide the axle shaft
into the housing so that the rough
forging of the shaft will not damage
the oil seal. Start the axle splines
into the side gear, and push the
shaft in until the bearing bottoms in
the housing.
