Steering Wheel Rotational Play
Check
1. Turn the front wheels to the straight ahead position.
2. Measure how far you can turn the steering wheel
left and right without moving the front wheels.
. lf the play is within the limit, the gearbox and
linkage are OK.. lf the playexceedsthe limit, adjustthe rack guide
{see page '17-13). lf the play is still excessive after
rack guide adjustment, inspect the steering
linkage and gearbox {see page 17-5).
BOTATIONAL PLAY: 0 10 mm (0-0.39 in.l
+:

Power Assist Check
Start the engine, and let it idle.
Attach a commercially available spring scale to the
steering wheel. With the engine idling and the
vehicle on a clean, dry floor, pull the scale as
shown, and read it as soon as the tires begin to turn.
\
1.
3. lf the scale reads no morethan 29 N (3.0 kgf,6.6 lbf),
the power assist is OK. lf it reads more, check these
items:
. Front tire pressure. Steering linkage (see page 17-5). Rack gulde adjustment (see page 17-13). EPS system (see page 17-18)

Steering Wheel Removal
SRS components are located in this area. Review the
SRS component locations (see page 23-13), and
precautions and procedures (see page 23-14) in the SRS
section before performing repairs or service.
1. Align the front wheels straight ahead, then remove
the driver's airbag from the steering wheel (see
page 23-113).
2. Disconnect the cruise control sevresume switch
connector (A), and loosen the steering wheel nut
{B).
i

3. Install a commercially available steering wheel
puller {A) on the steering wheel (B). Free the
steering wheel from the steering column shaft by
turning the pressure bolt (C) ofthe puller.
Note these items when removing the steering
wheel:. Do not tap on the steering wheel orthesteering
column shaft when removing the steering wheel.. lf you thread the puller bolts (D) intothewheel
hub more than 5 threads, the bolts will hit the
cable reel and damage it. To prevent this, install
a pair of jam nuts 5 threads up on each puller bolt.
D
Bemove the steering wheel puller, then remove the
steering wheel nut and steering wheel from the
sleerino column.
