CAUTION
When holding the steering gear box assembly in a vice,
secure its mounting positions. If it is secured in any other
place, the gear housing may become deformed or dam-
aged.
Using special tool MB991006, rotate the pinion gear at the rate
of one rotation in approximately 4 to 6 seconds to check the
total pinion torque.
Standard value: 0.6
− 1.7 N⋅m (5.3 − 15.0 in-lb)
[Change in torque: 0.4 N
⋅m (3.5 in-lb) or less]
NOTE: When measuring, remove the bellows from the rack
housing.
NOTE: Measure the pinion torque through the whole stroke of
the rack.
NOTE: If the measured value is not within the standard range,
first adjust the rack support cover, and then check the total pin-
ion torque again.
NOTE: If the total pinion torque cannot be adjusted to within the
standard range by adjusting the rack support cover, check the
rack support cover, rack support spring, rack support and
replace any parts if necessary.
TIE ROD SWING RESISTANCE CHECK
1. Using a spring balance, give 10 hard swings to the tie rod.
2. Measure the tie rod swing resistance with a spring balance.
Standard value: 11
− 35 N (35.4 − 82.7 lb) [1.4 − 4.9 N⋅m
(12.4
− 43.4 in-lb)]
3. If the measured value exceeds the standard value, replace
tie rod.
4. If the measured value is below the standard value, the tie
rod can be re-used if it swings smoothly without excessive
play.
TIE ROD END BALL JOINT DUST COVER CHECK
1. Check the dust cover for cracks or damage by pushing it
with your finger.
2. If the dust cover is cracked or damaged, replace the tie rod
end. (Refer to
NOTE: Cracks or damage of the dust cover may damage
the ball joint.
