INSPECTION
1. INSPECT POWER STEERING RACK
(a) Using a dial indicator, check for runout of the steering rack and teeth wear.
Maximum runout: 0.3 mm (0.0118 inch)
If the runout exceeds the maximum, replace the power steering gear assembly.

Turning torque: 0.98 to 3.92 Nm (10.0 to 40.0 kgf-cm, 8.7 to 34.7 inch lbs.)
If the turning torque is not as specified, replace the tie rod assembly LH.
