Steering Column: Testing and Inspection
STEERING WHEEL AND COLUMN INSPECTION
Steering Wheel Play Inspection
1. With the wheels in the straight-ahead position, gently turn the steering wheel to the left and right and verify that the play is within the specification.
- If the play exceeds the specification, either the steering joints are worn or the backlash of the steering gear is excessive. Correct as necessary.
Steering wheel play
- 0-30 mm {0-1.1 in}
Steering Wheel Looseness Inspection
1. Move the steering wheel as shown in the figure to inspect for column bearing wear, steering shaft joint play, steering wheel looseness, and column looseness.
- Repair or replace as necessary.
Steering Wheel Effort Inspection
1. Inspect the following points:
- Tire size and tire pressure
- Fluid level
- Drive belt deflection
2. With the vehicle on a hard, level surface, put the wheels in the straight-ahead position.
3. Remove the air bag module.
WARNING:
- Handling the air bag module improperly can accidentally deploy the air bag module, which may seriously injure you. Read AIR BAG SYSTEM WARNINGS before handling the air bag module. Air Bag System Service Warnings Air Bag System Service Cautions
4. Start the engine and warm the power steering fluid to 50-60 °C {122-140 °F}.
5. Measure the steering wheel effort using a torque wrench.
- If not within the specification, verify the following:
- No air in steering system
- No fluid leakage at hose or connectors
- Function of oil pump and steering gear
Steering wheel effort
- 7.8 Nm {80 kgf-cm, 69 in-lbf} max.
NOTE:
- To determine whether the steering effort is satisfactory or not, perform the inspection on another vehicle of the same model and under the same conditions, and compare the results.
- The steering wheel effort varies with conditions as shown below.
- Road conditions, such as dry or wet, and asphalt or concrete.
- Tire conditions, such as brand, wear, and tire pressure.
