Steel Wheel

WHEEL AND TIRE SYSTEM

3. Steel Wheel

A: REMOVAL

1) Apply the parking brake, and position select le-
ver or shift lever to “P” range (AT model) or “1st
gear” (MT model).
2) Set the shop jacks or a lift to the specified points,
and support the vehicle with its wheels slightly con-
tacting the floor.
3) Loosen the wheel nuts.
4) Raise the vehicle until its wheels are off the
ground using the jack or a lift.
5) Remove the wheel nuts and wheels.

NOTE:
• When removing the wheels, be careful not to
damage the hub bolts.
• Place the wheels with their outer sides facing up-
ward to prevent wheels from being damaged.

B: INSTALLATION

1) Remove dirt from the mating surface of the
wheel and brake rotor.
2) Attach the wheel to the hub by aligning the wheel
bolt holes with the hub bolts.
3) Temporarily attach the wheel nuts to the hub
bolts. (In the case of aluminum wheels, use SUBA-
RU genuine wheel nuts for aluminum wheels.)
4) Tighten the nuts by hand, making sure the wheel
hub hole is aligned correctly to the guide portion of
hub.
5) Tighten the wheel nuts in a diagonal selection to
the specified torque. Use a wheel nut wrench.

Wheel nut tightening torque:

120 N·m (12.2 kgf-m, 88.5 ft-lb)

CAUTION:
• Tighten the wheel nuts in two or three steps
by gradually increasing the torque on opposing
nuts, until they reach the specified torque.
• Do not push the wrench by foot. Always use
both hands when tightening the nuts.
• Make sure the bolt, nut and the nut seating
surface of the wheel are free from oil.
6) If a wheel is removed for replacement or for re-
pair of a puncture, retighten the wheel nuts to the
specified torque after driving 1,000 km (600 miles).

C: INSPECTION

1) Deformation or damage to the rim may cause air
leakage. Check the rim flange for deformation,
cracks or damage, and repair or replace as neces-
sary.
2) Jack-up the vehicle until wheels clear the floor.
3) Slowly rotate the wheel to check rim “runout” us-
ing a dial gauge.

Rim runout:

4) If the rim runout exceeds specifications, remove
the tire from the wheel and check runout with the
dial gauge attached to positions shown in the fig-
ure.

5) If the measured runout still exceeds specifica-
tions, replace the wheel.

A: REMOVAL

Refer to “Steel Wheels” for removal procedure of
aluminum wheels. <Ref. to WT-6, REMOVAL,
Steel Wheel.>

B: INSTALLATION

Refer to “Steel Wheels” for installation procedure of

D: CAUTION

Aluminum wheels are easily scratched. To main-
tain their appearance and safety, be careful of the
following:
1) Do not damage the aluminum wheels during re-
moval, installation, wheel balancing, etc. After re-
moving aluminum wheels, place them on a rubber
mat etc.
2) When washing the aluminum wheel, use neutral
synthetic detergent and water. Avoid using cleans-
ers containing abrasives, hard brushes or an auto-
matic car washer.

Wheel Balancing

WHEEL AND TIRE SYSTEM

5. Wheel Balancing

A: ADJUSTMENT

NOTE:
Because an adhesive type weight is adopted for
the outside balance weight of 17-inch and 18-inch
wheels, change the setting of the wheel balancer to
adhesive type weight.
1) Remove the balance weights.

CAUTION:
• Be careful not to damage the wheel.
• Completely remove the double-sided tape of
the adhesive weight from the wheel.
2) Using the wheel balancer, measure wheel bal-
ance.
3) Select a weight close to the value measured by
wheel balancer.

CAUTION:
Use SUBARU genuine balance weights.

Wheel Balancing

WHEEL AND TIRE SYSTEM

4) Install the selected weight to the point designat-
ed by the wheel balancer.

CAUTION:
• Degrease the wheel surface where the adhe-
sive type weight will be applied.
• Press the adhesive type weight by 25 N (2.5
kgf, 5.6 lb) or more per 5 g (0.18 oz) for 2 sec-
onds or more and attain full adhesion.
• Total application of the adhesive type weight
should be 100 g (3.53 oz) or less.
• The total weight of all adhesive weight on
models with transmitters (tire pressure sensor)
is to be 120 g (4.23 oz) or less.
5) Using the wheel balancer, measure the wheel
balance again. Check that wheel balance is cor-
rectly adjusted.

NOTE:
Knock-on type balance weights for aluminum
wheels can be used on any 15 to 18 inch aluminum
wheels.
