TIE ROD END BALL JOINT BREAKAWAY TORQUE CHECK

Required Special Tools

1. MB990326: Preload Socket
2. MB991113 or MB990635: Steering Linkage Puller

Scheme 1

Scheme 2

1. Use special tool MB991113 or MB990635 to disconnect the ball joint.
2. Move the ball joint stud several times and install the nut on the stud. Measure the ball joint breakaway torque with special tool MB990326. Standard value: 0.5 - 2.5 N.m (4.4 - 22.1 in-lb)
3. If the breakaway torque exceeds the standard value, replace the tie rod end.
4. If the breakaway torque is under the standard value, check the ball joint for end play or ratcheting. If no end play or ratcheting, the ball joint can be reused.
5. Tighten the nut to the specified torque and install a new cotter pin. Tightening torque: 29 +/- 4 N.m (21 +/- 4 ft-lb)

Scheme 3

Scheme 4

1. With the vehicle stopped on a flat and paved surface, turn the steering wheel to the straight ahead position.
2. Start the engine and check the engine idle speed. Standard value
3. Attach a spring scale to the outer circumference of the steering wheel and measure the steering force required to turn the steering wheel from the straight ahead position to the left and right (within a range of 1.5 turns). Also check to be sure that there is no significant fluctuation of the required steering effort. Standard value: Steering effort: 30 N (6.7 lb) or less Fluctuation allowance: 5.9 N (1.33 lb) or less

GEAR BOX TOTAL PINION TORQUE CHECK

Using special tool MB990228 or MB991006, rotate the pinion gear at the rate of one rotation in approximately 4 to 6 seconds to check the total pinion torque.

Scheme 5

Standard value: 0.8 - 1.9 N.m (6.9 - 16.5 in-lb)

[Change in torque: 0.7 N.m (6.1 in-lb) or less]

Note. When measuring, remove the bellows from the rack housing. Measure the pinion torque through the whole stroke of the rack.

If the measured value is not within the standard range, first adjust the rack support cover, and then check the total pinion torque again.

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.

Scheme 6

1. Give 10 hard swings to the tie rod.
2. Measure the tie rod swing resistance with a spring scale. Standard value: 4.0 - 18.6 N (17.8 - 82.7 lb) [1.0 - 4.9 N.m (8.7 - 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 reused if it swings smoothly without excessive play.

>> L << TOTAL PINION TORQUE ADJUSTMENT

Note. If the total pinion torque cannot be adjusted to the standard value within the specified return angle, check the rack support cover components and replace any parts if necessary.

Scheme 7

1. Using special tool MB990228 or MB991006, rotate the pinion shaft at the rate of one rotation in four to six seconds to check the total pinion torque and the change in torque. Standard value: Total pinion torque: 0.8 - 1.9 mm (6.9 - 16.5 in-lb) [Change in torque: 0.7 N.m (6.1 in-lb) or less]
2. If the total pinion torque or the change in torque is outside the standard value, return the rack support cover within 0 degree angle to 30 degree angle, and adjust again.
