Steel Wheel - Subaru 2002 IMPREZA Service Manual

3. Steel Wheel

A: REMOVAL
1) Apply parking brake, and position the select le-
ver to "P" or "LOW".
2) Set shop jacks or a lift to the specified point, and
support the vehicle with its wheels slightly contact-
ing the floor.
3) Loosen the wheel nuts.
4) Raise the vehicle until its wheels take off the
ground using a jack or a lift.
5) Remove the wheel nuts and wheels.
NOTE:
• While removing the wheels, prevent hub bolts
from damage.
NOTE:
• Place the wheels with their outer sides facing up-
ward to prevent wheels from damage.
B: INSTALLATION
1) Attach the wheel to hub by aligning the wheel
bolt hole with hub bolt.
2) Temporarily attach the wheel nuts to hub bolts.
(In the case of aluminum wheel, use SUBARU gen-
uine wheel nut for aluminum wheel.)
3) Manually tighten the nuts making sure the wheel
hub hole is aligned correctly to guide portion of hub.
4) Tighten the wheel nuts in a diagonal selection to
specified torque. Use a wheel nut wrench.
Wheel nut tightening torque:
90 N·m (9.1 kgf-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 tight-
ening of wheel nuts may cause wheels to "jud-
der".
• Do not depress the wrench with foot; Always
use both hands when tightening.
• Make sure the bolt, nut and nut seating sur-
face of the wheel are free from oils.
5) If a wheel is removed for replacement or for re-
pair of a puncture, retighten the wheel nuts to the
specified torque after running 1,000 km (600
miles).

3) Slowly rotate the wheel to check rim "runout" us-
ing a dial gauge.
Axial runout limit
4) If the rim runout exceeds specifications, remove
the tire from rim and check runout while attaching
dial gauge to positions shown in the figure.
5) If measured runout still exceeds specifications,
replace the wheel.
