Installation (cont'dl
Center the cable reel by first rotating it clockwise
until it stops. Then rotate it counterclockwise(approximately two turns) until the arrow mark on
the label points straight up. Reinstall the steering
wheel (see page 17-35).
Install the steering joint cov€r with the clamps and
clrps.

Troubleshooting
Noise and Vibration
NOTE; Pump noise in first 2 - 3 minutes after starting in cold weather is normal.
Humming
Rattle or chattering
Humming due to pulsation of fluid is normal, particularlv when the wheel isturned with the vehicle stooDed.
lf equipped with automatic trans-mission, the hum could be thetorque conveater or pump noise.
Confirm by temporarily removingthe pump belt.
High-pressure line touching theframe.Reposition the line.
Loose steering shaft connector,tie-rod. or balljoint.Check and tighten, or replacepaats as necessary.
Column shaft wobbling.Replace the column assembly.
Check the rack guide tor properadjustment (see page 17,33).Adiusi, if necess€ry.
Rattling sound and feeling when turning the steering wheel raght and left with theengine OFF is normal.
Pump noise, though not loud. trom the valve body unit can be heard whon turn-ing the steering wheel right or left. This is normat.
CAUTION: When imp€sting, do not hold the steering wheet a[ the way tothe right or the left.

IRack Guide Adjustment
NOTE: Perform rack guide adjustment with the wheels
in the straight ahead Position.
1. Loosen the rack guide screw locknut with the
cialtool.
'96 - '97 models:
Loosen the rack guide screw
'98 - '00 models:
Remove the rack guide screw and remove the old
sealant off of the threaded section.
Apply new sealant all around the threads. Loosely
installthe rack guide screw
Tighten the rack guide screw to 25 N'm (2.5 kgf'm.
18 lbf.ft), then loosen it.
Retighten the rack guide screw to 3 9 N'm (0.4 kgim,
2.9 lbf.ft), then back it off to specified angle.
Specified Return Angle: 20" max.
Tighten the locknut while holding the rack guide
screw.
Check for tight or loose steering through the com-
plete turning travel.
Perform following insPections:
. Steering operation (see page 17-30).
. Power assist with vehicle parked.

Fluid Replacement
Check the reservoir at regular intervals, and add fluid as
necessary.
CAUTION: Always us€ Genuine Honda Power Stearing
Fluid-V or S. Using any other type of power sto€ring

1. Raise the reservoir, then disconnect the return nose.
2. Connect a hose of suitable diameter to the discon-
nected return hose, and put the hose end in a suit-
able container.
CAUTION: Take care not to spill tho fluid on the
body and parts. Wipe off any spill€d fluid at oncs'
3. Start the engine, let it run at idle, and turn the steer-
ing wheel from lock-to-lock several times When
fluid stops running out of the hose, shut off the
engine, Discard the fluid.
4. Reinstall the return hose on the reservoir'
5. Fill the reservoir to the upper level line.
6. Start the engine and run it at fast idle, then turn the
steering trom lock-to-lock several times to bleed air
trom the system.
7. Recheck the fluid level and add some it necessary.
CAUTION: Do not fill the reservoir beYond the

CAUTION: Do not tap on the steering wheel or steering
column shaft when installing the stsering wheel.
NOTE: Before installing the steering wheel, align the
front wheels straight ahead.
1. Before installing the steering wheel, center the
cable reel, Do this by first rotating the cable reel
clockwise until it stops. Then rotate it counterclock-
wise approximately two turns The arrow mark on
the cable reel label should points straight up.
Install the steering wheel with the steering wheel
nut.
NOTE: Be sure the steering wheel shaft engages
the cable reel and canceling sleeve.
Attach the cruise control switches connector io the

Connect the horn connector.
Install the driver's airbag assembly, and confirm
proper system operation (see section 24).
Check the horn and cruise control switches for
proper operatrons.
