Inspection and Adjustment
Steering Operation
Steering Wheel Rotational Play
Place the front wheels in a straight ahead position andmeasure the distance the steering wheel can be turnedwithout moving the front wheels.
ROTATIONAL PLAY: 0 - 10 mm (0 - 0.4 in)
lf the play exceeds the service limit, perform rack guide
adjustment (see page lT-5).
lf the play is still excessive after rack guide adjustment,inspect the steering linkage and gearbox as descrjbed
Detow.

Rack Guide Adjustment
NOTE: Perform the rack guide adjustment with the
wheels in the straight ahead position.
1. Loosen the rack guide screw locknut with the spe-
cial tool, then loosen the rack guide screw.
LOCKNUT WRENCH, 40 mm07916 - SA5000r
Tighten the rack guide screw until it compresses the
spring and seats against the rack guide, then loosen
rt.
Retighten the rack guide screw to 4 N'm (0.4 kgf m,
2.9 lbf.ft), then back it off to specified angle.
Specilied Return Angle: 30' max.
Tighten the locknut while holding the rack guide
Check for tight or loose steering through the com-
plete turning travel.
Recheck steering effort (see page 17-4).

Removal
NOTE: Using solvent and a brush, to wash any oil and
dirt off the gearbox. Blow dry with compressed air.
1. Raise the front of vehicle, and support it on satety
stands in the proper locations (see section I ).
2. Remove the front wheels.
3. Remove the steering wheel (see page 17-35).
4. Remove the steering loint cover
Remove the steering joint lower bolt, and discon-
