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.
