While pulling outer socket slowly in 

±

11.5 mm (

±

0.453 in) range

from neutral position, make sure rack sliding force is within
specification.

d.

If rack sliding force is not within specification, overhaul steering
gear assembly.

CHECKING FRONT WHEEL TURNING ANGLE

●

Check front wheel turning angle after toe-in inspection. Place
front wheels on turning radius gauges and rear wheels on
stands. Check the maximum inner and outer wheel turning
angles for LH and RH road wheels.

●

With the engine at idle, turn steering wheel from full left stop to
full right stop and measure the turning angles.

●

Measure rack stroke if angles are outside the specified value.

●

Disassemble steering gear assembly to check the cause that
rack stroke is outside of the standard.

●

Steering angles are not adjustable. Check steering gear assem-
bly, steering column assembly and front suspension compo-
nents for wear or damage if any of the turning angles are
different from the specified value. Replace any of them, if any
non-standard condition exists.

REMOVAL

NOTE:
When reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned. This
will omit neutral position alignment procedure during spiral cable installation.

1.

Set vehicle to the straight-ahead position.

2.

Remove driver air bag module. Refer to 

SRS-42, "DRIVER AIR BAG MODULE"

 .

3.

Remove steering wheel lock nut after steering is locked.

4.

Remove steering wheel with the steering wheel puller [SST].

INSTALLATION

Installation is the reverse order of removal. For tightening torque, refer to 

PS-13, "COMPONENTS"

 .

NOTE:
Check the spiral cable neutral position after replacing or rotating spiral cable. Refer to 

SRS-44, "INSTALLA-

TION"

 .

CAUTION:

Do not twist spiral cable freely on excessively after it becomes tight (doing so may cause the cable to
be turn off).

–

Set rack of steering gear in the neutral position.
NOTE:
To get the neutral position of rack, turn gear-sub assembly and
measure the distance of inner socket, and then measure the
intermediate position of the distance.
