Metric Lug Nuts and Wheel Studs
All models use metric lug nuts and wheel studs.
Metric lug nuts and wheel studs size
M12 x 1.25
If broken stud or nut are found, be sure to replace both
stud and nut with new one.
Irregular and/or Premature Wear DescriptionS7RS0B2401003
Irregular and premature wear has many causes. Some
of them are as follows: incorrect inflation pressures, lack
of tire rotation, driving habits, improper alignment.
If the following conditions are noted, tire rotation is
necessary:
• Front tire wear is different from rear’s.
• Uneven wear exists across tread of any tires.
• Both sides of front tire wears are not even.
• Both sides of rear tire wears are not even.
• There is cupping, flat spotting, etc.
A wheel alignment check is necessary if following
conditions are noted:
• Both sides of front tire wears are not even.
• Wear is uneven across the tread of any front tire.
• Front tire treads have scuffed appearance with “feather” edges on one side of tread ribs or blocks.
Wear Indicators DescriptionS7RS0B2401004
Original equipment tires have built-in tread wear
indicators (1) to show when they need replacement.
These indicators (1) will app ear as 12 mm (0.47 in) wide
bands when the tire tread depth becomes 1.6 mm (0.063
in).
When the indicators (1) appear in 3 or more grooves at 6
locations, tire replacement is recommended.

Radial Tire Waddle DescriptionS7RS0B2401005
Waddle is side to side movement at the front and/or rear
of the vehicle. It is caused by the steel belt not being
straight within the tire. It is most noticeable at a low
speed, 8 to 48 kph (5 to 30 mph).
It is possible to locate the f aulty tire by road testing the
vehicle. If it is on the rear , the rear end of the vehicle
shakes from side to side or “waddles”. To the driver in
the seat, it feels as though someone is pushing on the
side of vehicle.
If the faulty tire is on the front, waddling is more visual.
The front sheet metal appears to be moving back and
forth and the driver feels as though he is at the pivot
point in vehicle.
Waddle can be quickly diagnosed by using Tire Problem
Detector (TPD) and following the equipment
manufacture’s recommendations.
If TPD is not available, an alternative method of
substituting known-good tire / wheel assemblies can be
used as follows, although it takes a longer time. 1) Ride vehicle to determine whether the front or rear
waddles.
2) Install tires and wheels that are known to be good (on similar vehicle) in place of those on waddling end
of vehicle. If waddling end cannot be identified,
substitute rear ones.
3) Road test again. If improvement is noted, reinstall originals one at a time till w addle causal tire is found.
If no improvement is noted, install known-good tires
in place of all four. Then reinstall originals in the
same manner.

Radial Tire Lead / Pull DescriptionS7RS0B2401006
“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 DescriptionS7RS0B2401007
There are two types of wheel an d 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.

9) Pull out drive shaft joint as follows. • For differential sideUsing tire lever (1), pull out drive shaft joint (2) so
as to release snap ring fitting of joint spline at
differential side.
• For center shaft side Using plastic hammer (3), drive out drive shaft
joint (2) so as to release snap ring fitting of joint

boots when installing drive shaft.
• Do not hit joint boot with hammer. Inserting joint only by hands is allowed.
• Make sure that differential side joint is inserted fully and its snap ring is seated as
it was.

procedure and noting the following points.
• Tighten each bolt and nut to the specified torque referring to “Front Drive Shaft Assembly Components
Location”.
• Tighten brake hose mounting bolt to specified torque.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at vari ous speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components in
the hydraulic system to deteriorate.

If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
