Start the engine with the steering wheel in the straight ahead position.
Measure the play while turning the steering wheel to the left and right.
Standard value Steering wheel free play : 30 mm (1.1 in.) |
If the play exceeds the standard value, inspect the connection between the steering shaft and steering linkage.
Place the front wheel on a turning radius gauge and measure the steering angle.
Standard value Wheel angle Inside wheel : 35.1° ± 1°30' Outside wheel : 30.7° |
If the measured value is not within the standard value, adjust the toe and inspect again.
After adjusting the tie rod, assemble the bellows so they are not twisted.
The inner steering angle is changed 0.86° per each rotation of the tie rod.
Disconnect the tie rod and knuckle with the special tool (09568-31000).
Shake the ball stud several times to check for looseness.
Mount two jam nuts on the ball joint, and then measure the ball joint starting torque.
Standard value 0.5-2.5 Nm (5-25 kg·cm, 0.36-1.78 lb·ft) |
If the starting torque exceeds the upper limit of the standard value, replace the tie rod end.
Even if the starting torque is below the lower limit of the standard value, check the play of the ball joint and replace if necessary.
The force required to turn the steering wheel and then return should be the same for both moderate turns and sharp turns.
When the steering wheel is turned 90° and held for a couple of seconds while the vehicle is being driven under 23-30kph (12-19 mph), the steering wheel should return to within 20° from its central position whenit is released.
If the steering wheel is turned very quickly, steering may be momentarily difficult. This is not a malfunction because the oil pump outputwill be somewhat decreased.
Position the vehicle on a level surface.
Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the fluid temperature to 50-60°C(122-140°F).
With the engine at idle, turn the steering wheel fully clockwise and counter-clockwise several times.
Make sure that there is no foaming or cloudiness in the reservoir fluid.
Stop the engine and check for any difference in fluid level between a stationary and a running engine.
If the fluid level varies 5 mm (0.2 in.) or more, bleed the system again.
If the fluid level suddenly rises after stopping the engine, further bleeding is required.
Incomplete bleeding will produce a chattering sound in the pump and noise in the flow control valve, and lead to decreased durability of the pump.
