6D ญ 2 MANUAL STEERING GEAR

DESCRIPTION AND OPERATION
MANUAL RACK AND PINION
The manual rack and pinion steering system consists of two main components: the rack and the pinion. The motion of the pinion is transferred through the pinion teeth that mesh with the teeth on the rack, which moves the rack. The force is then transmitted through the arms on the struts, which turn the wheels.

STEERING WHEEL RESTORATION
1. Turn the steering wheel fast to the right and left and turn it slowly as the same way. 2. Check if the steering wheel restoration for the wheel turning to right and the one to the left are same. 3. Turn the steering wheel to 90_ about 1ญ2 seconds and loosen the steering wheel during the low speed driving. 4. If the steering wheel restores above 70%, the steering wheel restoration is OK. 5. If the restoration is poor, check the tire pressure, steering gear preload, and steering gear operation. And repair the fault.

ADJUST THE FREE LOAD OF THE STEERING GEAR
1. Place the steering wheel in the straightญahead position. 2. Raise and suitably support the vehicle. 3. Check the torque of the adjuster plug. 4 When the measured torque is below the specification value or the measured torque is over the specification value, adjust the tightening torque. D Place the rack gear in the straightญahead position. D Tighten the adjust plug to 95 NSm (70 lb-ft). D Turn the steering wheel all the way to the right and the left about 5 times repeatedly. D Place the rack gear in the straightญahead position. D Loosen the adjust plug. D Tighten the adjust plug to 8 NSm (71 lb-in.). D Set the torque in the 0.8ญ1.3 NSm (8ญ12 lb-in.) by loosening the adjust plug to 0_ - 90_.

CHECK THE TURNING RESISTANCE OF THE TIE ROD END OR TIE ROD
1. Turn the ball joint of the tie rod end or the tie rod about 10 times. 2. Use a spring balance to check the turning resistance of each ball joint.
