Tie Rod End Ball Joint Rotation Torque Check
TIE ROD END BALL JOINT ROTATION TORQUE CHECKRequired Special Tools:
^ MB990326: Preload Socket
^ MB991897 or MB992011: Ball Joint Remover
CAUTION
^ Loosen the jam nut (tie-rod end connection) from the ball joint, but do not remove here. Use the special tool.
^ To prevent the special tool from dropping off, suspend it with a cord.
1. Install special tool MB991897 or MB992011 as shown in the figure.
2. Turn the bolt and knob to make the special tool jaws parallel, then hand-tighten the bolt. After tightening, check that the jaws are still parallel.
NOTE: To adjust the special tool jaws to be parallel, set the orientation of the knob as shown in the figure.
3. Unscrew the bolt to disconnect the ball joint.
4. Move the ball joint stud several times and install the nut on the stud. Using the special tool MB990326, measure the ball joint rotation torque.
Standard value: 2.9 Nm (26 in-lb) or less
5. If the rotation torque exceeds the standard value, replace the tie rod end.
6. If the rotation 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 re-used.
7. Install the tie rod end to the knuckle, then tighten a new jam nut to the specified torque.
Tightening torque: 52 ± 2 Nm (38 ± 1 ft-lb)
