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.

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.

Vehicle Inspection
There is some noise in all power steering systems. One of the most common is a hissing sound. Hiss is a high
frequency noise similar to that of a water tap being closed slowly. The noise is present in all valves that have a high
velocity steering fluid passing through an orifice. There is no relationship between this noise and steering perfor-
mance. The hissing sound is commonly heard during the following operations:
•Evident at a standstill
• At park with the engine running
• When the steering wheel is at the end of its travel

Removal & Installation
NOTE :
The following special tool is required to perform the repair procedure:
•CH-10002 - Ball Joint Separator
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly. (Tighten: Wheel mounting nuts to 110 N·m)
3. Loosen the tie rod jam nut (1). (Tighten: Tie rod jam nut to 15 N·m)
4. Remove the nut (1) attaching the outer tie rod end to the steering knuckle.
(Tighten: Outer tie rod end nut to 32 - 38 N·m)
5. Using special tool CH-10002, separate the outer tie rod end from the steering knuckle.
6. Remove the outer tie rod end from the steering rack.
NOTE :
When removing the outer tie rod end, count the number of revolutions when removing. This will aid in installation,
getting the toe setting close to where it needs to be when setting the final toe-in wheel alignment. 7. Installation is in the reverse order of removal.
Installation Notes:
• After installing the new tie rod end, perform a front end alignment procedure to reset the toe-in (See Front
Wheel Alignment in Section 10 Suspension).
