Pre-checking

• Make surethatwheel alignment iscorrect.

Wheel alignment:
Refer toSOS inFA section.

• Verify thatthesteering geariscentered beforeremoving
the steering wheel.

Checking
SST490BA
1.Check thatthesteering wheelisin the neutral position when
driving straight ahead.
2. Ifit is not inthe neutral position, removethesteering wheel
and reinstall itcorrectly.
3. Ifthe neutral position isbetween twoteeth,. loosen tie-rod
lock nuts. Turnthetie-rods bythe same amount inopposite
directions onboth leftand right sides.

Front Wheel Turning Angle •

1. Rotate steering wheelallthe way right andleft;measure
turning angle.

Turning angleoffull turns:
Refer toSOS inFA section.

2. Ifit is not within specification, checkrackstroke.

Refer toSOS (ST-35).
SMA127 Checking GearHousing Movement

1. Check themovement ofsteering gearhousing duringsta-
tionary steering onadry paved surface.
• Apply aforce of49 N(5 kg, 11Ib) tosteering wheeltocheck
the gear housing movement.
Turn offignition keywhile checking.

Movement ofgear housing:

:I:
2 mm
(:I:
0.08 in)orless

2. Ifmovement exceedsthelimit, replace mountinsulator after
confirming properinstallation ofgear housing clamps.
