service indicator DODGE NEON 2000 Service Owner's Guide

To install the differential bearing cup and cone on
the ring gear side, use Special Tool 5052, and Special
Tool C-4171.NOTE: The differential is serviced as an assembly.
The only parts that are serviceable within the differ-
ential are the differential bearing cups and cones. If
any other part fails within the differential, you must
replace the differential assembly along with the
transfer shaft.
CAUTION: Side gear end play must be BETWEEN
0.001 to 0.013 inch.

DESCRIPTION AND OPERATION
TIRE
Tires are designed and engineered for each specific
vehicle (Fig. 1). They provide the best overall perfor-
mance for normal operation. The ride and handling
characteristics match the vehicle's requirements.
With proper care they will give excellent reliability,
traction, skid resistance, and tread life.
Driving habits have more effect on tire life than
any other factor. Careful drivers will obtain, in most
cases, much greater mileage than severe use or care-
less drivers. A few of the driving habits which will
shorten the life of any tire are:²Rapid acceleration
²Severe application of brakes
²High-speed driving
²Taking turns at excessive speeds
²Striking curbs and other obstacles
²Operating vehicle with over or under inflated
tire pressures
Radial ply tires are more prone to irregular tread
wear. It is important to follow the tire rotation inter-
val shown in the section on Tire Rotation. This will
help to achieve a greater tread-life potential.

(1) Measure the total indicator runout on the cen-
ter of the tire tread rib. Record the indicator reading.
Mark the tire to indicate the high spot. Place a mark
on the tire at the valve stem location (Fig. 9).
(2) Break down the tire and remount it 180
degrees on the rim (Fig. 10).
(3) Measure the total indicator runout again. Mark
the tire to indicate the high spot.
(4) If runout is still excessive (in excess of 1.524
mm or 0.060 in.), the following procedures must be
done.
²If the high spot is within 102 mm (4.0 in.) of the
first spot and is still excessive, replace the tire.
²If the high spot is within 102 mm (4.0 in.) of the
first spot on the wheel, the wheel may be out of spec-
ifications. Refer to Wheel and Tire Runout.
²If the high spot is NOT within 102 mm (4.0 in.)
of either high spot, draw an arrow on the tread from
second high spot to first. Break down the tire and
remount it 90 degrees on rim in that direction (Fig.
11). This procedure will normally reduce the runout
to an acceptable amount.

METHOD 2 (RELOCATE TIRE ON WHEEL)
Rotating tire on wheel is particularly effective
when there is run out in both tire and wheel.
Remove tire from wheel and remount wheel on hub
in former position.
Check the radial run out of the wheel (Fig. 8). The
radial runout should be no more than 0.762 mm
(0.030 inch).
Check the lateral run out of the wheel (Fig. 9). The
lateral run out should be no more than 0.762 mm
(0.030 inch).
If the point of greatest wheel radial run out is near
the original chalk mark, remount the tire on the rim
180 degrees from its original position. Recheck the
run out. If this does not reduce the run out to an
acceptable level, replace the wheel and/or the tire.
SERVICE PROCEDURES
TIRE AND WHEEL BALANCE
Balancing need is indicated by vibration of seats,
floor pan, or steering wheel. The vibration will be
noticed mostly when driving over 90 km/h (55 mph)
on a smooth road.It is recommended that a two plane dynamic bal-
ancer be used when a wheel and tire assembly
require balancing. Static balancing should be used
only when a two plane balancer is not available.
Off-vehicle tire and wheel balancing is recom-
mended to be used on this vehicle.
NOTE: If on vehicle equipment is being used to bal-
ance the tire /wheel assemblies, remove the oppo-
site tire/wheel from the vehicle.
For static balancing, find the location of heavy spot
on tire/wheel causing the imbalance. Counter balance
wheel directly opposite the heavy spot. Determine
weight required to counterbalance the area of imbal-
ance. Place half of this weight on theinnerrim
flange and the other half on theouterrim flange
(Fig. 10).
For dynamic balancing, the balancing equipment is
designed to indicate the location and amount of
weight to be applied to both the inner and outer rim
flanges (Fig. 11).
