A: INSPECTION OF WHEEL RUNOUT
1) Jack-up vehicle until wheels clear the floor.
2) Slowly rotate wheel to check rim“runout”using a dial
gauge.
G4M0299
Axial runout limit Radial runout limit
Steel wheel 1.5 mm (0.059 in)
Aluminum wheel 1.0 mm (0.039 in)
3) If rim runout exceeds specifications, remove tire from
rim and check runout while attaching dial gauge to posi-
tions shown in figure.
4) If measured runout still exceeds specifications, replace
the wheel.
9. Aluminum Wheel
A: INSPECTION
Inspection for aluminum wheels is basically the same as
the one for steel wheels. However, check the rim flange for
cracks or damage, and replace (not repair) aluminum
wheel if air leakage is found.
B: PRECAUTIONS
Aluminum wheels are easily scratched. To maintain their
appearance and safety, do the following:
1) Do not damage aluminum wheels during removal,
disassembly, installation, wheel balancing, etc. After
removing aluminum wheels, place them on a rubber mat,
etc.
2) While vehicle is being driven, be careful not to ride over
sharp obstacles or allow aluminum wheels to contact the
shoulder of the road.
3) When installing tire chain, be sure to install it properly
not to have a slack; otherwise it may hit wheel while driv-
ing.
4) When washing aluminum wheel, use neutral synthetic
detergent and water. Avoid using the cleanser including
abrasive, hard brushes or an automatic car washer.

10. Wheel Balancing
1) Proper wheel balance may be lost if the tire is repaired
or if it wears. Check the tire for dynamic balance, and repair
as necessary.
2) To check for dynamic balance, use a dynamic balancer.
Drive in the balance weight on both the top and rear sides
of the rim.
3) Some types of balancer can cause damage to the
wheel. Use an appropriate balancer when adjusting the
wheel balance.
4) Use genuine balance weights.
Service limit: A
Weight for steel wheel;
1.6—2.0 mm (0.063—0.079 in)
Weight for aluminum wheel;
4.6—5.4 mm (0.181—0.213 in)
CAUTION:
55 g (1.94 oz) weight used with aluminum wheel is
not available.
Balance weights are available for use with any of 14-
to 15-inch wheels.
11. Installation of Wheel Assembly to
Vehicle
1) Attach the wheel to the hub by aligning the wheel bolt
hole with the hub bolt.
2) Temporarily attach the wheel nuts to the hub bolts. (In
the case of aluminum wheel, use SUBARU genuine wheel
nut for aluminum wheel.)
3) Manually tighten the nuts making sure the wheel hub
hole is aligned correctly to the guide portion of hub.
4) Tighten the wheel nuts in a diagonal selection to the
specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
88±10 N⋅m (9±1 kg-m, 65±7 ft-lb)
CAUTION:
Tighten the wheel nuts in two or three steps by
gradually increasing the torque and working
diagonally, until the specified torque is reached. For
drum brake models, excess tightening of wheel nuts
may cause wheels to “judder”.
Do not depress the wrench with a foot; Always use
both hands when tightening.
Make sure the bolt, nut and the nut seating surface
of the wheel are free from oils.
5) If a wheel is removed for replacement or for repair of a
puncture, retighten the wheel nuts to the specified torque
after running 1,000 km (600 miles).
