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.

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

Description
The steering gear used is the rack-and-pinion type with power assist. It is mounted on the front suspension sub-
frame. The outer ends of the outer tie rods attach to the front knuckles.
NOTE :
The power steering gear should not be serviced or adjusted. If a malfunction or steering fluid leak occurs with the
steering gear, the complete steering gear needs to be replaced.
Operation
The steering wheel turns the pinion. The rack is a long flat bar with geared teeth on one side. The rack teeth mesh
with the teeth on the pinion gear. Rotation of the pinion moves the rack from left to right and right to left. The tie rod
then causes the wheels to turn to the left or right.

NOTE :
Before removing the front suspension sub-frame from the vehicle, the location of the sub-frame must be marked on
the body of the vehicle. Do this so the sub-frame can be relocated, upon reinstallation, against the body of vehicle in
the same location as before removal. If the front suspension sub-frame is not reinstalled in exactly the same location
as before removal, the preset front wheel alignment settings (caster and camber) may be lost.
19. Using a jack, slowly lower the sub-frame enough to access the intermediate shaft coupling at the steering gear pinion shaft.
20. Remove the steering gear assembly.
21. Installation is in the reverse order of removal.
Installation Notes:
• After installing the new steering gear, perform a front end alignment procedure to reset the toe-in (See Front
Wheel Alignment in Section 10 Suspension).
