INSPECTION
GEAR BOX PINION TOTAL ROTATION TORQUE CHECK
1. Using the special tool, turn the pinion gear at a speed
of one rotation per 4 to 6 seconds to measure total rotation
torque.
Standard values:
Total rotation torque: 0.6 ± 1.5 Nm
Torque fluctuation: 0.5 Nm or less
NOTE
(1) Remove the bellows from the rack housing before
measuring.
(2) Measure the total rotation torque by turning the special
tool left and right 180 from the neutral position.
2. If the standard values are not met, adjust the pinion total
rotation torque. (Refer to P.37-26.)
3. In case the adjustment is impossible, disassemble and
check the components, and repair if necessary.
Caution
Secure the steering gear box and linkage in their
mounting positions only. Otherwise, deformation or
damage could result.
TIE ROD SWING RESISTANCE CHECK
1. Swing the tie rod 10 times hardly.
2. With the tie rod end downwards as shown, use a spring
scale to measure swing resistance (swing torque).
Standard value: 5 ± 17 N (1.5 ± 4.9 Nm)
3. If the measured value is above the standard value, replace
the tie rod.
4. If below, check the ball joint for looseness or ratcheting.
The tie rod is still serviceable when the ball joint swings
smoothly.
TIE ROD END BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing
it with finger.
2. If the dust cover is cracked or damaged, replace the tie
rod end. (Refer to P.37A-19, 20.)
NOTE
A cracked or damaged dust cover may damage the ball
joint. Replace the dust cover when it is damaged during
service work.
