REMOVAL &INSTALLATION
# See Figures 1, 2, 3, and 4
1. Park the vehicle on a level surface.
2. Remove the jack, tire iron and, if necessary,
the spare tire from their storage compartments.
3. Check the owners manual, or refer to Section
1 of this manual for the jacking points on your vehi-
cle. Then, place the jack in the proper position,
4. If equipped with lug nut trim caps, remove
them by either unscrewing or pulling them off the lug
nuts, as appropriate. Consult the owners manual, if
necessary.
5. If equipped with a wheel cover or hub cap,
insert the tapered end of the tire iron in the groove
and pry off the cover.
6. Apply the parking brake and block the diago-
nally opposite wheel with a wheel chock or two.
*Wheel chocks may be purchased at your
local auto parts store, or a block of wood cut
into wedges may be used. If possible, keep
one or two of the chocks in your tire storage
compartment, in case any of the tires has to
be removed on the side of the road. 7. If equipped with an automatic
transmission/transaxle, place the selector lever in P
or Park; with a manual transmission/transaxle, place
the shifter in Reverse.
8. With the tires still on the ground, use the tire
iron/wrench to break the lug nuts loose.
*If a nut is stuck, never use heat to loosen it
or damage to the wheel and bearings may
occur. If the nuts are seized, one or two
heavy hammer blows directly on the end of
the bolt usually loosens the rust. Be careful,
as continued pounding will likely damage the
brake drum or rotor.
9. Using the jack, raise the vehicle until the tire
is clear of the ground. Support the vehicle safely us-
ing jackstands.
10. Remove the lug nuts, then remove the tire
and wheel assembly.
To install:
11. Make sure the wheel and hub mating sur-
faces, as well as the wheel lug studs, are clean and
free of all foreign material. Always remove rust from
the wheel mounting surface and the brake rotor or
drum. Failure to do so may cause the lug nuts to
loosen in service.
12. Install the tire and wheel assembly and hand-
tighten the lug nuts. 13. Using the tire wrench, tighten all the lug nuts,
in a crisscross pattern, until they are snug.
14. Raise the vehicle and withdraw the jackstand,
then lower the vehicle.
15. Using a torque wrench, tighten the lug nuts in
a crisscross pattern to 65-80 ft. lbs. ( 90-l 10 Nm).
Check your owners manual or refer to Section 1 of
this manual for the proper tightening sequence.
Do not overtighten the lug nuts, as this may
cause the wheel studs to stretch or the brake
disc (rotor) to warp.
16. If so equipped, install the wheel cover or hub
cap. Make sure the valve stem protrudes through the
proper opening before tapping the wheel cover into
position.
17. If equipped, install the lug nut trim caps by
pushing them or screwing them on, as applicable.
18. Remove the jack from under the vehicle, and
place the jack and tire iron/wrench in their storage
compartments. Remove the wheel chock(s).
19. If you have removed a flat or damaged tire,
place it in the storage compartment of the vehicle and
take it to your local repair station to have it fixed or
replaced as soon as possible.
Inspect the tires for lacerations, puncture marks,
nails and other sharp objects. Repair or replace as
necessary. Also check the tires for treadwear and air
pressure as outlined in Section 1 of this manual.
Check the wheel assemblies for dents, cracks, rust
and metal fatigue. Repair or replace as necessary.

1. Raise and support the appropriate end of the
vehicle safely using jackstands, then remove the
wheel.
2. Remove the brake pads and caliper. Sup-
port the caliper aside using wire or a coat hanger.
For details, please refer to Section 9 of this man-
ual.
3 Remove the outer wheel bearing
and liff off
the rotor. For details on wheel bearing removal, in-
stallation and adjustment, please refer to Section 1 of
this manual.
4. Properly support the rotor using press bars,
then drive the stud out using an arbor press.
*If a press is not available, CAREFULLY
drive the old stud out using a blunt drift.
MAKE SURE the rotor is properly and evenly
supported or it may be damaged.
To install:
5. Clean the stud hole with a wire brush and
start the new stud with a hammer and drift pin. Do
not use any lubricant or thread sealer.
6. Finish installing the stud with the press.
*If a press is not available, start the lug
stud through the bore in the hub, then posi-
tion about 4 flat washers over the stud and
thread the lug nut. Hold the hub/rotor while
tightening the lug nut, and the stud should be
drawn into position. MAKE SURE THE STUD
IS FULLY SEATED, then remove the lug nut
and washers.
7. Install the rotor and adjust the wheel bear-
ings
8. Install the brake caliper and pads.
9. Install the wheel, then remove the jackstands
and carefully lower the vehicle.
10. Tighten the lug nuts to the proper torque.

3. If necessary to provide clearance, remove the
brake shoes, as outlined in Section 9 of this manual.
4. Using a large C-clamp and socket, press the
stud from the axle flange.
5. Coat the serrated part of the stud with liquid
soap and place it into the hole. and thread the lug nut. Hold the flange while tighten-
ing the lug nut, and the stud should be drawn into
position. MAKE SURE THE STUD IS FULLY SEATED,
then remove the lug nut and washers.
7. If applicable, install the brake shoes.
