3-2 SEPARATION OF THE AXLE BRACKET AND THE

FRONT AXLE (4WD)

(1) DISASSEMBLY

Parts exposed for inspection by this operation:

(1) Pivot bushing

(2) Thrust collar

(3) O-ring

a) Hold the chassis with a chain block or a jack.

b) Drain the front axle oil. (The wheel should be removed

in advance.)

Oil capacity 3.7 qt. (3.5 liters) (3.0 Imp. qt.)

e) Remove the pivot mounting (F and R) and the front axle

can then be removed. (Fig. 7)

Fig. 7

c) Detach the drag rod assembly from the drag arm. (Fig. Note: As straight pins are installed in the pivot mountings, pull 5) the front axle straight out so as not to deform the pins.

Fig. 5 (1) Drag rod

(2) Drag arm

d) Remove the front wheel drive shaft and related parts.

(Fig. 6)

Fig. 6

The wheels which have been removed to drain the oil should be reinstalled before removing the front axle.

(2) REASSEMBLY

Reassemble the parts in reverse order of disassembly,

following these instructions:

a) Never fail to install straight pins when reassembling the

pivot mounting.

b) The pivot mounting tightening bolts should be tightened

to the specified torque. (Fig. 8)

2-5

Fig. 8

Bolt tightening torque on both sides

36-43 ft.-lb. (5.0-6.0 kg-m)

c) When reassembling the front wheel drive shaft, each

splined part should be lubricated with grease ahead of

time.
