Description
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the
handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering,
good directional stability, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufacturer and type
of equipment used. The manufacturer’s instructions should always be followed to ensure accuracy of the alignment.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front Axle
•Camber
• Caster
• Toe-in
Rear Axle
• Camber
• Toe-in
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb
height specification. Curb height is the normal riding height of the vehicle. It is measured from a certain point on the
vehicle to the ground or a designated area while the vehicle is sitting on a flat, level surface.
Operation
Curb Height Measurement
The wheel alignment is to be checked and all alignment adjustments made with the vehicle at its required curb height
specification.
• Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack.
• The tires are to be inflated to the recommended pressure.
• All tires are to be the same size as standard equipment.
• Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
• Vehicle height is not adjustable.
• If the measurement is not within specifications, inspect the vehicle for bent or weak suspension components.
• Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for
a match.
• Once removed from the vehicle, compare the coil spring height to a new or known good coil spring. The
heights should vary if the suspect spring is weak.
NOTE :
Prior to reading the curb height measurement, the front and rear of the vehicle must be jounced to settle the sus-
pension. Induce jounce by pushing down on the center of the bumper (fascia), using care not to damage the vehicle,
moving the vehicle up and down, gradually increasing the suspension travel with each stroke. Release the bumper at
the bottom of each stroke, repeating this action several times. Perform this to both front and rear suspensions an
equal number of times.
Pre-Wheel Alignment Inspection
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary cor-
rections must be made to the vehicle to ensure proper alignment. 1. Verify the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
2. The passenger and luggage compartments of the vehicle should be free of any load that is not factory equip- ment.

must be the same size and in good condition with
approximately the same tread wear.
4. Check the front tire and wheel assemblies for excessive radial runout.
5. Inspect all suspension component fasteners for looseness and proper torque.
6. Inspect all ball joints and all steering linkage for looseness and any sign of wear or damage.
7. Inspect the rubber bushings on all the suspension components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
8. Check vehicle curb height.
Wheel Alignment Setup
1. Position the vehicle on an alignment rack.
2. Install all required alignment equipment on the vehicle, per the alignment equipment manufacturer’s instructions. On this vehicle, a four-wheel alignment is recommended.
3. Read the vehicle’s current front and rear alignment settings. Compare the vehicle’s current alignment settings to the vehicle specifications for camber, caster and toe-in.
NOTE :
Prior to reading the vehicle’s alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear
first, then front) by grasping the center of the bumper and jouncing each end of the vehicle an equal number of
times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.

Description
Tires are designed and engineered for each specific vehicle. They provide the best overall performance 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.
Tire Identification
•Tire type, size, load index and speed rating are encoded in the letters and numbers imprinted on the side wall
of the tire.
Spare Tire
• A full size spare tire and wheel assembly is standard equipment on this vehicle. The original tire should be
repaired or replaced at the first opportunity, then reinstalled.
Operation
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 careless drivers. A few of the driving habits which will shorten the life of any tire
are:
•Rapid acceleration
• Severe application of brakes
• High-speed driving
• Taking turns at excessive speeds
• Striking curbs and other obstacles
• Operating vehicle with over or under inflated tire pressures

Vehicle Inspection
Visual inspection of the vehicle is recommended prior to road testing or performing any other procedure. Raise the
vehicle on a suitable hoist.
Inspect the following:
•Inspect tires and wheels for damage, mud packing and unusual wear; correct as necessary.
• Check and adjust tire pressure to the pressure listed on the label attached to the driver’s door opening.
Tire and Wheel Vibration
Tire and wheel imbalance, runout and force variation can cause vehicles to exhibit steering wheel vibration.
NOTE :
Balance equipment must be calibrated and maintained per equipment manufacturer’s specifications.
Tire Wear Patterns
Tire wear patterns can be traced to the following tire conditions:
•Under inflation will cause wear on the shoulders of tire.
• Over inflation will cause wear at the center of tire.
• Excessive camber causes the tire to run at an angle to the road. One side of tread is then worn more than the
other.
• Excessive toe-in or toe-out causes wear on the tread edges and a feathered effect across the tread.
NOTE :
Tread wear indicators are molded into the bottom of the tread grooves. When tread depth is 1.6 mm, the tread wear
indicators will appear as a band. Tire replacement is necessary when indicators appear in two or more grooves, or
if localized balding occurs.
Wheel Out-Of-Round Inspection
• Raise vehicle and securely support it.
• Attach a dial indicator on the edge of the rim and measure its unevenness.
• Replace the rim if necessary.10

Tire Repair
Description
Tires are designed and engineered for each specific vehicle. They provide the best overall performance 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.
WARNING!
Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire failure.
In order to maintain the speed capability of the vehicle, replacement tires must have speed ratings equal to or
higher than those fitted to the vehicle as original equipment. If tires with lower speed ratings are fitted, the vehi-
cle’s handling may be affected and the speed capability of the vehicle may be lowered to the maximum speed
capability of the replacement tires. To avoid an accident resulting in severe or fatal injury, consult the tire man-
ufacturer in regards to maximum speed ratings.
Replacement Procedure
Note the following guidelines when replacing a tire:
•It is recommended that tires equivalent to the original equipment tires be used when replacement is needed.
• Failure to use equivalent replacement tires may adversely affect the safety and handling of the vehicle.
• The use of tires smaller than the minimum tire size approved for the vehicle can result in tire overloading and
failure.
• Use tires that have the approved load rating for the vehicle and never overload them.
• Failure to equip the vehicle with tires having adequate speed capability can result in sudden tire failure and
loss of vehicle control.
• The use of oversize tires may cause interference with vehicle components. Under extremes of suspension and
steering travel, interference with vehicle components may cause tire damage.
Perform the following when replacing a tire: 1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly.
3. Deflate the tire completely before removing the tire from the wheel.
4. Use lubrication such as a mild soap solution when dismounting or mounting tire.
5. Replace the tire with a tire approved for the vehicle.
6. Use tools free of burrs or sharp edges which could damage the tire or wheel rim.
7. Before mounting tire on wheel, make sure all rust is removed from the rim bead and repaint if necessary.
8. Balance the wheel assembly.
9. Install the wheel assembly and install the wheel mounting nuts. (Tighten: Wheel mounting nuts to 110 N·m)
Repair Procedure
Note the following guidelines when performing a tire repair:
•For proper repairing, a radial tire must be removed from the wheel.
• Repairs should only be made if the defect, or puncture, is in the tread area.
• The tire should be replaced if the puncture is located in the sidewall.
Perform the following when repairing a tire: 1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly.
3. Deflate the tire completely before removing the tire from the wheel.
4. Use lubrication such as a mild soap solution when dismounting or mounting tire.
5. Repair the tire only if the defect, or puncture, is in the tread area.
6. Use tools free of burrs or sharp edges which could damage the tire or wheel rim.
7. Before mounting tire on wheel, make sure all rust is removed from the rim bead and repaint if necessary.

Diagnostic Help
Brake diagnosis involves determining if the concern is related to a mechanical, hydraulic, electrical or vacuum oper-
ated component.
NOTE :
The brake reservoir fluid level will decrease in proportion to normal lining wear.
NOTE :
Brake fluid tends to darken over time. This is normal and should not be mistaken for contamination.
Preliminary Brake Check:
•Check the condition of the tires and wheels. Damaged wheels and worn, damaged or under inflated tires can
cause a pull, shudder, vibration and a condition similar to brake grab.
• If a complaint was based on noise while braking, check the suspension components. Jounce the front and the
rear of vehicle and listen for anything that might be caused by a loose, worn or damaged suspension or steer-
ing component.
• Inspect the brake fluid level and condition.
1. If the fluid level is abnormally low, look for any evidence of leaks at the calipers, brake lines, master cyl-
inder and at the Antilock Brake System (ABS) Hydraulic Control Unit (HCU).
2. If the fluid appears to be contaminated, drain a sample to examine.
• The system will have to be flushed if the fluid is separated into layers, or contains a substance other than
brake fluid. The system seals, cups, hoses, master cylinder and HCU will also have to be replaced after flush-
ing. Use clean brake fluid to flush the system.
• Check the parking brake operation. Verify free movement and full release of the cables and the lever. Also note
if the vehicle was being operated with the parking brake partially applied.
• Check the brake pedal operation. Verify that the pedal does not bind and has adequate free play. If the pedal
lacks free play, check the pedal and the power booster for looseness or for a binding condition. DO NOT road
test the vehicle until the condition is located and corrected.
• Check the vacuum booster check valve and vacuum supply hose.
• If the preliminary checks appear to be OK, road test the vehicle.

1. Install standard wheel mounting nuts, flat side torotor, on all the wheel studs (2). Progressively
tighten the nuts in a crisscross pattern to 110 N·m.
2. Mount a dial indicator (1), with wheel, or equiva- lent, to the knuckle. Position the dial indicator
wheel to contact the rotor braking surface approxi-
mately 10 mm from the outer edge of the rotor.
3. Slowly rotate the brake rotor (3) checking lateral runout, marking the low and high spots. Record
these measurements.
4. Check and record the runout on the opposite side of the rotor in the same fashion, marking the low
and high spots.
5. Compare runout measurement to specification.
6. If runout is in excess of specifications, check the lateral runout of the hub face.

Removal & Installation
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the tire and wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
3. Remove rear caliper (1) (See Rear Caliper Removal & Installation in Section 12 Brakes).
4. Slide the rear brake rotor (3) off the hub and bear- ing.
5. Installation is in the reverse order of removal.
Inspection
Excessive runout or wobble in a rotor can increase pedal travel due to piston knock-back. This increases guide pin
sleeve wear due to the tendency of the caliper to follow the rotor wobble.
Braking Surface Inspection
Light braking surface scoring and wear is acceptable. If heavy scoring or warping is evident, the rotor must be resur-
faced or replaced. Excessive wear and scoring of the rotor can cause improper lining contact on the rotor’s braking
surface. If the ridges on the rotor are not removed before new brake pads are installed, improper wear of the shoes
will result. Some discoloration or wear of the rotor surface is normal and does not require resurfacing when linings
are replaced. If cracks or burned spots are evident, the rotor must be replaced.
