6. 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 See: Power Steering/Power Steering Pump/Testing and Inspection
RACK SLIDING FORCE
1. Disconnect lower joint and steering knuckle from steering gear assembly. Refer to See: Steering Gear/Service and Repair/Removal and
