Inspection and Adjustment
STEERING GEAR PRELOAD
Measure preload in worm gear.
1. Mount steering gear to Tool (KV48100301) and place it in a
vise, as shown in the illustration.
2. Turn worm gear several times by hand completely to the left
and right (full lock to lock).
3. Measure preload at  360É from straight-ahead position.
a. Turn worm gear counterclockwise until full lock position.
Then turn clockwise more than two turns until the straight-
ahead position.
Straight-ahead position is the position where the two mat-
ing marks are in line (approx. 765É from full lock position).
b. Turn worm gear one full turn (360É) clockwise and measure
total preload at this position.
c. Turn worm gear two full turns (720É) counterclockwise and
measure total preload.
Total preload at  360É from straight-ahead position:
: 0.4 - 1.2 N×m (0.04 - 0.12 kg-m, in-lb)
4. Measure total preload at straight-ahead position.
a. Place worm gear in straight-ahead position. See step 3.a.
b. Measure total preload in straight-ahead position.
Total preload at straight-ahead position:
: 0.6 - 1.6 N×m (0.06 - 0.16 kg-m,5-14in-lb)
5. If either one of the above measured values are not within
specifications, adjust total preload by turning sector shaft
adjusting screw. Tighten adjusting screw lock nut with tools.
Lock nut:
:30N×m (3 kg-m, 22 ft-lb)
