10. 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:
ITighten 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 tight-
ening of wheel nuts may cause wheels to ªjud-
derº.
IDo not depress the wrench with a foot;
Always use both hands when tightening.
IMake 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).
11. Tire Rotation
If tires are maintained at the same positions for a
long period of time, uneven wear results.
Therefore, they should be periodically rotated.
This lengthens service life of tires.
CAUTION:
When rotating tires, replace unevenly worn or
damaged tires with new ones.

5. Measure steering effort. Adjust or replace.
*1 If tires and/or rims are wider, the load to power steering system is the more. Accordingly, in a condition, for example
before fluid warms-up, relief valve may work before maximum turning angle. In this case, steering effort may be heavy.
When measured hydraulic pressure is normal, there is no abnormal thing.
*2 In cold weather, steering effort may be heavy due to increased flow resistance of cold fluid. After warming up engine,
turn steering wheel from stop to stop several times to warm up fluid. Then if steering effort reduces normally, there is no
abnormal thing.
*3 In cold weather or with insufficient warm-up of engine, steering effort may be heavy due to excessive drop of idling
when turning steering wheel. In this case, it is recommended to start the vehicle with increasing engine speed than usual.
Then if steering effort reduces normally, there is no abnormal thing.
