TIE ROD END BALL JOINT STARTING TORQUE CHECK



BALL JOINT LOOSENESS CHECK


1.Raise the vehicle.
2.Inspect the ball joint for looseness in the axial direction while shaking the tie-rod end vertically. If there is looseness, replace the tie-rod end assembly.(Refer to .)

BALL JOINT ROTATIONAL STARTING TORQUE CHECK



1.
caution
  • To prevent the ball joint thread damage, only loosen the nut from the ball joint (do not remove it), then disconnect the steering knuckle from the tie-rod using the special tool.
  • To prevent the special tool from dropping off, suspend it with a rope.
Install the ball joint remover (special tool: MB9921897 or MB992011) as shown in the figure.

2.Turn the bolt and knob to make the special tool insert horizontal, then hand-tighten the bolt. After tightening, verify that the insert is still horizontal.
note To adjust the special tool jaws to be parallel, set the knob as shown in the figure so that it functions as a fulcrum of the jaws.
3.Turn the bolt and disconnect the tie-rod end from the steering knuckle.

4.Move the ball joint stud back and forth for several times, then attach the nut to the stud, and use the preload socket (special tool: MB990326) to measure the ball joint rotation starting torque.
Standard value: 2.9 N·m or less
5.If the measurement value exceeds the standard value, replace the tie rod assembly.(Refer to .)
