      NOTE:

      Do not overtighten the vise.

    2. Install the nut to the stud bolt.
    3. Flip the ball joint back and forth 5 times.
    4. Using a torque wrench and the nut, turn the stud bolt continuously at a rate of 2 to 4 seconds per turn, and check the turning torque on the 5th turn.

      Standard Turning Torque

      0.49 to 3.43 N.m (5 to 34 kgf/cm, 5 to 30 in.lbf)

      HINT: 

      If the turning torque is not within the specified range, replace the tie rod assembly LH with a new one.

    5. Check that the dust cover is not cracked and that there is no grease on it.

      HINT: 

      If the dust cover is cracked or there is grease on it, replace the tie rod assembly LH with a new one.

  2. INSPECT TIE ROD ASSEMBLY RH 

    HINT: 

    Perform the same procedure as for the LH side.

  3. INSPECT TOTAL PRELOAD 
    NOTE:

    Inspect the total preload in a no-load condition by removing the tie rod assemblies RH and LH, and steering rack boots.

    1. Install SST to the pinion shaft and turn it left and right 5 times or more.

    2. Using SST and a torque wrench, turn the pinion shaft continuously at a rate of 4 to 6 seconds per turn to inspect the total preload of the rack and pinion power steering gear assembly.

      Standard Preload

      1.61 to 3.3 N.m (17 to 33 kgf/cm, 15 to 29 in.lbf)

      NOTE:

      Inspect the total preload around the steering rack center position.

      HINT: 

      If the total preload is not within the specified range, replace the rack and pinion power steering gear assembly with a new one.
