REMOVAL OF FRONT LEAF SPRINGS

1. BE SURE TO BLOCK THE REAR WHEELS.

Fig. 2 SM17-087A
2. USING A SOCKET WRENCH, LOOSEN THE WHEEL
NUTS A LITTLE.
Clean off any rust or dirt on the hub bolts with a wire
brush, before loosening the wheel nuts.
NOTE: ● Do not remove the wheel nuts, but leave
them loosened.
● Hub bolts and wheel nuts on the right side
of the truck have right-hand threads, and
hub bolts and wheel nuts on the left side

FRAME WITH STANDS.

WARNING
When jacking up the front axle, make sure that the
jack is correctly placed to the axle, and then lift up
the axle. Do not get under the vehicle when it is
supported by a jack only. It is very dangerous be-
cause the jack might slip. Use safety stands which
Fig. 4 SM17-280 have sufficient strength and stability to support the
truck whenever you need to work under it.

4. REMOVE THE WHEEL NUTS AND REMOVE THE TIRE.

NOTE: When removing the wheels, do not damage
the hub bolt threads.

Fig. 5 SM17-394
5. REMOVE THE SHOCK ABSORBER.

safety glasses to protect your eyes.
Fig. 8 SM17-398
NOTE: Insufficient spread of the staked part will
cause damage to the threads of spring pin,
when loosening the nut.
3. Remove the front spring pin and thrust washers from
the spring bracket with a copper bar and hammer.
NOTE: ● When removing the left spring pin, discon-
nect the drag link from the pitman arm in
accordance with CHAPTER 12, STEERING.
● Do not damage the drag link dust cover.

Fig. 10 SM17-400
2. INSPECT THE U-BOLTS AND SHACKLE FOR WEAR
OR DAMAGE.
3. INSPECT THE SPRING BUMPER FOR DAMAGE.

Fig. 11 SM17-978

4. MEASURE THE WEAR OF THE THRUST WASHER.
