Steering Gear: Testing and Inspection

POWER STEERING: STEERING GEAR: INSPECTION

1. INSPECT TIE ROD ASSEMBLY LH





(a) Secure the tie rod LH in a vise.

(b) Install the nut to the stud bolt.

(c) Flip the ball joint stud back and forth 5 times.

(d) Using a torque wrench, turn the nut continuously at a rate of 2 to 4 seconds per turn and take the torque reading of the 5 the turn.

Standard turning torque:

0.49 to 3.43 N*m (5.0 to 35 kgf*cm, 4.34 to 30.38 in.*lbf)

2. INSPECT TIE ROD ASSEMBLY RH

HINT
Use the same procedures described for the LH side.

3. INSPECT POWER STEERING CONTROL VALVE





(a) Check the bearing rotation condition and check for abnormal noise.

If the bearing is worn or damaged, replace the control valve.

(b) Coat the bearing with molybdenum disulfide lithium base grease.

4. INSPECT CYLINDER END STOPPER





(a) Check the inside of the bushing of the stopper for cracks.

If faulty, replace the bushing.

(b) Apply molybdenum disulfide lithium base grease to the inside of the bushing.

5. INSPECT POWER STEERING RACK





(a) Using a dial indicator, check for runout of the steering rack and teeth wear.

Maximum runout:

0.03 mm (0.0118 in.)

(a) If runout exceeds the maximum, replace the rack & pinion power steering gear.

(b) Check the back surface for wear and damage.

If the steering rack is worn or damaged, replace the rack & pinion power steering gear.

6. INSPECT POWER STEERING CONTROL VALVE LOWER BEARING





(a) Check the bearing of the rack housing for pit-marks or damage.
