Title: STEERING GEAR / LINKAGE: STEERING LINKAGE: INSPECTION (2008 LX570)

INSPECTION

1. INSPECT TIE ROD END SUB-ASSEMBLY LH



(a) Install the nut.

(b) Flip the ball joint stud back and forth 5 times as shown in the illustration.

(c) Using a torque wrench, turn the nut continuously at a rate of 3 to 5 seconds per turn and check the torque reading on the 5th turn.

Turning torque:

0.981 to 3.432 N*m (10.0 to 35.0 kgf*cm, 8.692 to 30.375 in.*lbf)

HINT:

Make sure the dust cover of the tie rod end ball joint has no cracks or damage. If necessary, replace the tie rod end.

2. INSPECT TOTAL PRELOAD


(a) Put matchmarks on the dust cover and steering link.

HINT:

Make sure that the steering link is centered when placing matchmarks.

(b) Remove the dust cover.

(c) Temporarily install the 2 steering rack ends to the power steering rack.

NOTICE:

Do not fully turn the power steering rack without the steering rack ends as it may damage the oil seal in the rack housing.


(d) Using SST, fully turn the power steering rack right and left 10 times to settle it.

SST: 09616-00011


(e) Using SST, turn the control valve and measure the preload.

SST: 09616-00011

Standard preload (turning):

2.4 N*m (24 kgf*cm, 21 in.*lbf)

If the turning torque is not as specified, replace the power steering link.

NOTICE:

After setting the steering rack to the neutral point, align the dust cover rib with the power steering protrusion.

HINT:

  • Measure the standard preload at the steering rack neutral point.
  • The steering control valve is fully turned when turned 3.14 times. Half of the distance from the fully turned position is the neutral point.


(f) After inspecting the preload, align the matchmarks and install the dust cover.

HINT:

Perform the inspection with the steering link centered.
