6. Install the pinion shaft grommet (A). Align the slotin the pinion shaft grommet with the lug portion (B)
on the torque sensor. The grommet must not have
a gap at the mating surface of the grommet and the
torque sensor.

(C), the EPS motor angle sensor 6P connector (D)
on the right side of the gearbox mounting bracket. 8. Install the harness clips (A) to the harness clamp

then loosely install the new front subframe
mounting bolts.
NOTE: Be sure that the pinion shaft grommet is in
place securely. Check whether the pinion shaft
grommet is not turning up. Incorrect installation
can cause leakage of water, mud, and noise.

34. Install the steering wheel (see page 17-8).
35. With the tires raised off the ground (vehicle on a
lift), check for the following symptoms by turning
the steering wheel fully to the right and left several
times.
Rubbing sound
coming from the
lower steering
column area. Steering column joint
is contacting the cover.
Grating sound from
the lower steering
column area, or a
rough feeling during
steering. Poor engagement of
the pinion shaft
serrations.
Noise from around
the steering wheel
during steering. Poor engagement of
the SRS cable reel with
the steering wheel, or a
damaged cable reel.
36. Install the air cleaner housing (see page 11- 345).
37. Install the under cowl panel and cowl cover (see page 20-163). 38. Do the battery terminal reconnection procedure
(see page 22-68), and do these tasks:
 Turn the ignition switch to ON (II) and check that the SRS indicator comes on for about 6 seconds
and then goes off.
 Make sure the horn and turn signal switches work properly.
 Make sure the steering wheel switches work properly.
39. After installation, do the following checks:  Check the steering wheel spoke angle. If steeringspoke angles to the right and left are not equal
(steering wheel and rack are not centered),
correct the engagement of the joint/pinion shaft
splines.
 Set the steering column to the center tilt position, and to the center telescopic position, then check
the wheel alignment and adjust (see page 18-5).
 Make sure the steering wheel spokes are centered.
 Start the engine, and let it idle. Turn the steering wheel from lock-to-lock several times. Check that
the EPS indicator does not come on.
 Do the memorizing for the torque sensor neutral position (see page 17-22).
