Repair procedures
| Service Adjustment Procedure |
| Steering Wheel Play Inspection |
| 1. |
Turn the steering wheel so that the front wheels are facing straight ahead. |
| 2. |
Measure the distance that the steering wheel can be turned without moving the front wheels.
|
| 3. |
If the play exceeds standard value, inspect the steering column, shaft, and linkages |
| Checking Stationary Steering Effort |
| 1. |
Position the vehicle on a level surface and place the steering wheel in the straight ahead position. |
| 2. |
Start the engine and turn the steering wheel from lock to lock several times to warm up the power steering fluid. |
| 3. |
Attach a spring scale to the steering wheel. With the idle RPM, pull the scale and read it as soon as the tires begin to turn.
|
| 4. |
If the measured value exceeds standard value, inspect the steering gear box. |
