Radial Tire Lead / Pull DescriptionS6RW0D2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from
the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed
• Rear tires will not cause lead.
Balancing Wheels DescriptionS6RW0D2401007
There are two types of wheel and tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.Dynamic balance, as shown in figure, is the equal
distribution of weight on each side of the wheel
centerline so that when the tire spins there is no
tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause
shimmy.
Inflate tires to recommended pressure
Road test vehicle on level unrouned road in both directions
Switch front tires side to side and road test again
Lead corrected,
if roughness results, replace tiresLeads in same directionLeads reverses direction

Lead remains install a known-good
tire in place of other front tire

Repair Instructions
Wheel Discs InspectionS6RW0D2406006
Inspect each wheel disc for dents, distortion and cracks.
A disc in badly damaged condition must be replaced.
Wheel Balance Inspection and AdjustmentS6RW0D2406001
Refer to “Balancing Wheels Description”.
Deposits of mud, etc. must be cleaned from inside of rim.
WARNING!
Stones should be removed from the tread in
order to avoid operator injury during spin
balancing and to obtain good balance.

Each tire should be inspected for any damage, then
balanced according to equipment manufacturer’s
recommendation.
Off-Vehicle Balancing
Most electronic off-vehicle balancers are more accurate
than the on-vehicle spin balancers. They are easy to use
and give a dynamic (two plane) balance. Although they
do not correct for drum or disc unbalance as does on-
vehicle spin balancing, this is overcome by their
accuracy, usually to within 1/8 ounce.
On-Vehicle Balancing
On-vehicle balancing methods vary with equipment and
tool manufacturers. Be sure to follow each
manufacturer’s instructions during balancing operation.
WARNING!
Wheel spin should be limited to 55 km/h (35
mph) as indicated on speedometer.
This limit is necessary because speedometer
only indicates one-half of actual wheel speed
when one drive wheel is spinning and the
other drive wheel is stopped.
Unless care is taken in limiting drive wheel
spin, spinning wheel can reach excessive
speeds. This can result in possible tire
disintegration or differential failure, which
could cause serious personal injury or
extensive vehicle damage.

CAUTION!
For vehicle equipped with ABS, using on-
vehicle balancing method with ignition
switch ON may set malfunction diagnostic
trouble code (DTC) of ABS even when system
is in good condition.
Never turn ignition switch ON while spinning
wheel.

Tire RotationS6RW0D2406002
To equalize wear, rotate tires periodically as shown in
figure.
Refer to “Wheel (with Tire) Removal and Installation”.

Wheel (with Tire) Removal and InstallationS6RW0D2406003
Removal
CAUTION!
Never use heat to loosen tight wheel because
the application of heat to wheel causes the
wheel life shorter and the wheel bearing
damage.

1) Loosen wheel nuts by approximately 180° (half a
rotation).
2) Hoist vehicle.
3) Make sure that the vehicle will not fall off by trying to
move vehicle body in both ways.
4) Remove wheel nuts except one.
5) Support the wheel and/or tire not to drop the wheel
and then remove the nut left with the wheel.
Installation
For installation, reverse removal procedure, noting the
following.
• Wheel nuts must be tightened in sequence and to
specified torque to avoid bending wheel or brake disc
or drum as shown in the figure.
NOTE
Before installing wheels, remove any build-
up of corrosion on wheel mounting surface
and brake disc or drum mounting surface by
scraping and wire brushing. Installing wheels
without good metal-to-metal contact at
mounting surfaces can cause wheel bolts to
loosen, which can later allow a wheel to
come off while vehicle is moving.

Tire Mounting and DismountingS6RW0D2406004
WARNING!
Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s safety
hump and cause serious personal injury.
Do not exceed specified pressure when
inflating. If specified pressure will not seat
beads, deflate, re-lubricate and reinflate.
Over inflation may cause bead to break and
cause serious personal injury.

Use a tire changing machine to mount or dismount tires.
Follow equipment manufacturer’s instructions. Do not
use hand tools or tire irons alone to change tires as they
may damage tire beads or wheel rim.
Rim bead seats should be cleaned with a wire brush or
coarse steel wool to remove lubricants, old rubber and
light rust. Before mounting or dismounting a tire, bead
area should be well lubricated with approved tire
lubricant.
After mounting, inflate 330 kPa (47.9 psi) pressure so
that beads are completely seated. Then adjust pressure
to specified shown in the tire placard.
Tire RepairS6RW0D2406005
There are many different materials and techniques on
the market to repair tires. As not all of these work on all
types of tires, tire manufacturers have published detailed
instructions on how and when to repair tires. These
instructions can be obtained from each tire
manufacturer.

General Description
Front Drive Shaft ConstructionS6RW0D3111001
A constant velocity ball joint is used on the wheel side of both right and left side drive shaft assemblies. For A/T
vehicle, a tripod type constant velocity joint is used on the differential side and center shaft side. For M/T vehicle, a
double offset type constant velocity joint (DOJ) is used on the differential side and center shaft side. The drive shaft
can slide through the tripod joint or the double offset joint (DOJ) in the extension/contraction direction.
