(b) Install the nut to the stud bolt.

(c) Flip the ball joint back and forth 5 times.

(d) 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.

(e) 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

NOTICE:

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

(a) Install SST to the pinion shaft and turn it left and right 5 times or more. SST: 09616-00011

(b) 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:

1.5 to 3.05 N*m (16 to 31 kgf*cm, 14 to 26 in.*lbf)

NOTICE:

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.
