Press a new wheel bearing (A) into the knuckle (B)
using the old bearing (C), a steel plate {D). the
special tool, and a press. Place the wheel bearing
on the knuckle with the pack seal side facing (metal
color) toward the inside. Be careful not to damage
the sleeve of the pack seal.

. Be careful notto damagethe balljoint bootwhen
installing the knuckle.. Tighten all mounting hardware to the specified
lOrque values.. Torque the castle nut to the lower torque
specification, then tighten it only far enough to
align the slot with the ball joint pin hole. Do not
align the castle nut by loosening it.
. Install a new look pin on the castle nut after
torquing.. Use a new spindle nut on reassembly.. Before installing the spindle nut, apply a small
amount of engine oil to the seating surface of the
nut. After tightening, use a drift to stake the
spindle nut shoulder against the driveshaft.
. Before installlng the brake disc, clean the mating
surface of the front hub and the inside of the
brake disc.. Before installing the wheel, clean the mating
su rface of the brake disc and the inside of the
wneet.. Check the front wheel alignment, and adjust it if
necessary (see page 18-4).

Does the blower motor run on all speeds?
YES Go to step 3.
NO Troubleshoot the blower motor circuit (see
page 21-20).
3. Turn the ignition switch OFF.
4. Disconnect heater control panel connectorA ('14P).

Compressor Replacement
1. lf the compressor is marginally operable, run the
engine at idle speed, and let the air conditioning
work for a few minutes, then shut the engine off.
2. Make sure you have the anti-theft code for the radio,
then write down the frequencies for the radio's
preset buttons.
3. Disconnect the negative cable from the battery.
4. Recover the refrigerant with a recovery/recycling/
charging station (see page 21-53).
5. Remove the alternator (see page 4-29).
6. Remove the Ay'C condenser fan assembly (see page
10-10).
7. Disconnectthe compressor clutch connector (A),
remove the bolts, then disconnect the suction line(B) and the discharge line (C)from the compressor.
Plug or cap the lines immediately after
disconnecting them to avoid moisture and dust
contamination.

9. Installthe compressor in the reverse order of
removal, and note these items:
. Before installing the new compressor, check for
metal or other contamination in the line. Replace
any contaminated parts.. lf you're installing a newcompressor, you must
calculate the amount of refrigerant oil to be
removed from it (see page 21-6).. Replace the O-rings with new ones at each fitting,
and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings
for HFC-134a {R-134a) to avoid leakage,. Use refrigerant oil (KElHlN SP-'10) for HFC-134a
KEIHIN spiral type compressor only.. To avoid contaminatlon, do not return the oilto
the container once dispensed, and never mix it
with other refrigerant oils.. lmmediately after using the oil, reinstallthe cap
on the container, and seal it to avoid moisture
absorption.. Do not spill the refrigerant oil on the vehicle; it
may damage the paint. lf the refrlgerant oil
contacts the paint, wash it off immediately.. Charge the system (see page 21-55).. Do the engine control module (ECM) idle learn
procedure (see page 11-'139).. Enter the antitheft code for the radio, then enter
the customer's radio station presets.
