On-Vehicle Inspection and ServiceINFOID:0000000001327712
CHECKING CONDITION OF INSTALLATION
Check installation condition of steering gear assemb ly, front suspension, axle and steering column.
Check if movement exists when steering wheel is mo ved up and down, to the left and right and to the axial
direction.
Check if the mounting bolts for steering gear assembly are loose or not. Refer to PS-17
.
CHECKING STEERING WHEEL PLAY
1. Set tires to the straight ahead, start engine, then turn steering wheel to the left and right lightly, and mea-
sure steering wheel movement on the outer circumfe rence when steering wheel is turned up to the point
where tires start moving.
CHECKING NEUTRAL POSITION ON STEERING WHEEL
Check neutral position on steering wheel after confirming that front wheel alignment is correct. Refer to FSU-5,
"Wheel Alignment Inspection".
1. Set vehicle to the straight direction, chec k if steering wheel is in the neutral position.
2. If it is not in the neutral position, remo ve steering wheel and reinstall it correctly.
3. If the neutral position cannot adjust in the two teeth of steering gear assembly, loosen outer socket lock
nuts of steering outer sockets, then adjust outer so cket by the same amount in the opposite direction.
CHECKING STEERING WHEEL TURNING FORCE
1. Park vehicle on a level and dry surface, set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating te mperature. [Make sure temperature of fluid is
approximately 50 to 80 °C (122 to 176 °F).]
NOTE:
Tires need to be inflated normal pressure.
4. Check steering wheel turning force when steering wheel has been turned 360 ° from neutral position.
NOTE:
Multiply the distance L from the hook of spring balance to the
center of steering wheel by the measurement value with a spring
balance.
5. If steering wheel turning force is out of the specification, check
rack sliding force and relief hydraulic pressure of oil pump.
Regarding relief hydraulic pressure of oil pump, refer to PS-27, "
On-Vehicle Inspection and Service".
