(3) Install the six nuts attaching rear bumper rein-
forcement to frame rail extensions and tighten to 27
N´m (20 ft. lbs.) torque (Fig. 4).
(4) Install rear bumper fascia. (Refer to 13 -
FRAMES & BUMPERS/BUMPERS/REAR FASCIA -
INSTALLATION).
REAR FASCIA - SCUFF PAD
REMOVAL
The scuff pad may not be salvageable during the
removal process. The scuff pad should be replaced if
damaged or broken. Check availability before servic-
ing. The scuff pad serviceability is improved if the
rear fascia is to be removed for service.
NOTE: If the rear fascia is to be removed for other
service issues or If the scuff pad is to be reused
use the steps below.
(1) Remove rear bumper fascia.(Refer to 13 -
FRAMES & BUMPERS/BUMPERS/REAR FASCIA -
REMOVAL)
(2) Using a trim stick, pry up the rear edge of the
scuff pad while squeezing the rear locking tabs from
underneath the fascia to release the rear edge of
scuff pad from the rear bumper fascia. Pull the scuff
pad up and squeeze the remaining tabs to release the
remaining of the scuff pad. (Fig. 5).
NOTE: If the rear fascia is to not to be removed for
other service issues use the step below.
(3) Using a trim stick, pry up the rear edge of the
scuff pad to release tabs from the rear bumper fascia
and pull scuff pad to release the forward tabs (Fig.
5).
INSTALLATION
(1) Verify that there are fifteen slots in the fascia.
(2) Place scuff pad in position (Fig. 5).
(3) Align and insert the center forward tab.
(4) Align the remaining tabs and press into the
slots, starting in the center and working outboard.
(5) Assure all tabs are fully engaged into the fas-
cia.(6) If rear bumper fascia has been removed install.
(Refer to 13 - FRAME & BUMPERS/BUMPERS/

Inspect for the following:
²Verify correct (OEM) wheel and tire, as well as
correct wheel weights. Aluminum wheels require
unique wheel weights. They are designed to fit the
contour of the wheel (Fig. 1).
²Inspect tires and wheels for damage, mud pack-
ing and unusual wear; correct as necessary.
²Check and adjust tire air pressure to the pres-
sure listed on the label attached to the rear face of
the driver's door.
ROAD TEST
Road test vehicle on a smooth road for a least five
miles to warm tires (remove any flat spots). Lightly
place hands on steering wheel at the 10:00 and 2:00
positions while slowly sweeping up and down from 90 to
110 km/h (55 to 70 mph) where legal speed limits allow.
Observe the steering wheel for:
²Visual Nibble (oscillation: clockwise/counter-
clockwise, usually due to tire imbalance)
²Visual Buzziness (high frequency, rapid vibra-
tion up and down)
To rule out vibrations due to brakes or powertrain:
²Lightly apply brakes at speed; if vibration occurs
or is enhanced, vibration is likely due to causes other
than tire and wheel assemblies.
²
Shift transmission into neutral while vibration is
occurring; if vibration is eliminated, vibration is likely
due to causes other than tire and wheel assemblies.
For brake vibrations, (Refer to 5 - BRAKES -
BASE/HYDRAULIC/MECHANICAL/ROTORS -
DIAGNOSIS AND TESTING).
For powertrain vibrations, (Refer to 3 - DIFFEREN-
TIAL & DRIVELINE - DIAGNOSIS AND TESTING).
For tire and wheel assembly vibrations, continue
with this diagnosis and testing procedure.
TIRE AND WHEEL BALANCE
(1) Balance the tire and wheel assemblies as nec-
essary following the wheel balancer manufacturer's
instructions and using the information listed in Stan-
dard Procedure - Tire And Wheel Balance. (Refer to
22 - TIRES/WHEELS - STANDARD PROCEDURE)
(2) Road test the vehicle for at least 5 miles, fol-
lowing the format described in Road Test.
(3) If the vibration persists, continue with this
diagnosis and testing procedure.
TIRE AND WHEEL RUNOUT/MATCH MOUNTING
(1)System Radial Runout.This on-the-vehicle
system check will measure the radial runout includ-
ing the hub, wheel and tire.
(a) Raise vehicle so tires clear floor. (Refer to
LUBRICATION & MAINTENANCE/HOISTING -
STANDARD PROCEDURE)
(b) Apply masking tape around the circumfer-
ence of the tire in the locations to be measured
(Fig. 2). Do not overlap the tape.
(c) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. System radial runout should
not exceed 0.76 mm (0.030 inch) with no tread
ªdipsº or ªsteps.º Tread ªdipsº and ªstepsº can be
identified by spikes of the dial indicator gauge.
²Tread9dips9; Rapid decrease then increase in
dial indicator reading over 101.6 mm (4.0 inch) of
tread circumference.
²Tread9steps9; Rapid decrease or increase in dial
indicator reading over 101.6 mm (4.0 inch) of tread
circumference.
(d) If system runout is excessive, re-index the
tire and wheel assembly on the hub. Remove
assembly from vehicle and install it back on the
hub two studs over from original mounting posi-
tion. If re-indexing the tire and wheel assembly
corrects or reduces system runout, check hub
runout and repair as necessary (Refer to 5 -
BRAKES - BASE/HYDRAULIC/MECHANICAL/
ROTORS - DIAGNOSIS AND TESTING).
(e) If system runout is still excessive, continue
with this diagnosis and testing procedure.
(2)Tire and Wheel Assembly Radial Runout.
This radial runout check is performed with the tire
and wheel assembly off the vehicle.
(a) Remove tire and wheel assembly from vehicle
and install it on a suitable wheel balancer.
(b) Check system runout using Dial Indicator
Set, Special Tool C-3339A with 25-W wheel, or
equivalent. Place the end of the indicator against
each taped area (one at a time) (Fig. 2) and rotate
the tire and wheel. Radial runout should not

exceed 0.76 mm (0.030 inch) with no tread ªdipsº
or ªsteps.º Tread ªdipsº and ªstepsº can be identi-
fied by spikes of the dial indicator gauge.
(c) If runout exceeds limits, mark the original
location of the tire on the wheel at the valve stem
(Fig. 3). Also, mark the tire and wheel to indicate
the original high spot of the assembly and record
the runout measurement.
(d) If runout exceeds limits, the tire will need to
be dismounted from the wheel to verify wheel vs.
tire contribution. Refer to Wheel Runout below.
(3)Lateral Runout.Lateral runout for the vehi-
cle system as well as the tire and wheel assembly
should be less than 0.76 mm (0.030 inch). The same
procedure and theory described for radial runout can
also be applied to identify and reduce lateral runout.
(4)Wheel Runout.This runout check is per-
formed as follows:
(a) Dismount the tire from the wheel.
(b) Mount the wheel back on the wheel balancer.
(c) Measure radial runout of the wheel at the
tire bead seat (Fig. 4). Runout should not exceed
0.254 mm (0.010 inch) for aluminum wheels and
0.508 mm (.020 inch) for steel wheels. Replace the
wheel if it exceeds the limit.
(d) Measure lateral runout of the wheel at the
tire bead seat (Fig. 5). Runout should not exceed
0.762 mm (0.030 inch) for all wheels. Replace the
wheel if it exceeds the limit.
(5)Match Mounting.If the wheel runout is
within specifications, tire and wheel assembly runout
can be improved by re-indexing (match mounting)
the tire to the wheel as described below.
