COMPLETE AXLE REMOVAL/INSTALLATION
I t is n o t necessary to remove t h e complete
axle
from the vehicle for routine service. However, i f t h e
differential housing or the axle shaft tubes are dam-
aged, t h e complete axle can be removed and i n s t a l l e d
d a t h e f o l l o w i n g procedures.
REMOVAL
(1) Raise t h e vehicle to a comfortable w o r k i n g
leight t h a t w i l l also enable support stands to be i n -
stalled a t the f r o n t o f the rear springs.

(3) Remove t h e rear wheels/tires.
(4) Disconnect t h e brake f l u i d tube f i t t i n g s f r o m
t h e wheel cylinders and cap t h e fittings t o prevent

(7) Remove t h e shock absorber lower a t t a c h i n g
bolts a n d t h e rear s p r i n g U-bolt nuts and t h e U -
bolts.
(8) Remove the complete axle from the vehicle.
(9) W a s h and clean t h e outer surface o f the axle
w i t h a n appropriate cleaning solution and d r y t h e
surface w i t h compressed air.
INSTALLATION
(1) W i t h the vehicle supported a t the f r o n t o f the
rear springs, position the rear axle spring pads over
the s p r i n g center bolts.
(2) I n s t a l l t h e s p r i n g U-bolts and nuts, and t h e
shock absorber lower bolts. T i g h t e n the nuts w i t h the
specified torque (Refer to Group 17—Springs a n d
Shock Absorbers).
(3) Connect the p a r k i n g b r a k e cables.
(4) Connect t h e brake f l u i d tube f i t t i n g s to t h e
wheel cylinders, and "bleed" and adjust the brakes.
(5) A l i g n the i n s t a l l a t i o n reference m a r k s and a t -

shaft (axle) yoke. T i g h t e n t h e U-joint clamp bolts
w i t h 19 t o 23 N-m (170 to 200 in-lbs) torque.
(6) I n s t a l l t h e rear wheels/tires and t i g h t e n t h e
nuts i n t h e correct t i g h t e n i n g sequence (Fig. 12) w i t h
the specified torque (Refer to Group 22—Tires A n d
Wheels f o r the specification).
STANDARD DIFFERENTIAL SERVICE
CAUTION: When rear axle service is necessary, or
when the axle is being rotated either via the engine
or by other means, both rear wheels must be raised
off the surface so that they are free to rotate.

Y
I t is not n e c e s s a r y to r e m o v e the complete axle
to s e r v i c e a s t a n d a r d differential.
(1) Raise the vehicle on a hoist, position supports
under t h e vehicle frame a t t h e front of t h e rear
springs a n d t h e n lower the rear of the hoist.
(2) Remove t h e rear wheels/tires and t h e brake
drums.
