TIE ROD END BALL JOINT TURNING TORQUE CHECK



1.
caution
  • Do not remove the tie rod end nut from the ball joint. Loosen it and use special tool to avoid possible damage to the ball joint threads.
  • Hang special tool with cord to prevent it from falling.
Install special tool ball joint remover (MB991897) as shown in the figure.

2.Turn the bolt and knob as necessary to make the jaws of special tool parallel, tighten the bolt by hand and confirm that the jaws are still parallel.
note When adjusting the jaws in parallel, make sure the knob is in the position shown in the figure.
3.Tighten the bolt with a wrench to disconnect the tie rod end.

4.Move the ball joint stud several times and install the nut on the stud. Using special tool preload socket (MB990326), measure the ball joint turning torque.
Standard value: 3.9 N·m or less
5.If the turning torque exceeds the standard value, replace the tie rod end. (Refer to )
6.If the turning torque is under the standard value, check the ball joint for axial play or ratcheting. If no axial play or ratcheting, the ball joint can be re-used. (Refer to )
7.
caution Always use a new ball joint nut as it is a self-locking nut.
Install the tie rod end to the knuckle, then tighten a new self-locking nut to the specified torque.
Tightening torque: 25 ± 5 N·m
