(b) To prevent oil seal lip damage, wind vinyl tape on the serrated part of the control valve shaft.
(c) Push the valve assembly into the control valve housing.
NOTICE:
Be careful not to damage the teflon rings and oil seal lip.
|
(d) Coat a new O-ring with power steering fluid, and install it to the bearing guide nut. |
|
(e) Using SST, torque the nut.

Torque:
24.5 N·m {250 kgf·cm, 18ft·lbf}
NOTICE:
Be careful not to damage the oil seal lip.
|
(f) Using a punch, stake the nut. |
|
7. INSTALL CONTROL VALVE HOUSING WITH CONTROL VALVE ASSEMBLY
(a) Coat a new O-ring with power steering fluid, and install it to the valve housing.
(b) Align the matchmarks on the valve housing and rack housing, and install the valve housing with the valve assembly to the rack housing.
(c) Torque the 2 bolts.
Torque:
18 N·m {180 kgf·cm, 13ft·lbf}
8. INSTALL POWER STEERING GEAR HOUSING OIL SEAL
9. INSTALL RACK GUIDE SUB-ASSEMBLY, RACK GUIDE SPRING AND RACK GUIDE SPRING CAP

(b) Torque the rack guide spring cap.
Torque:
25 N·m {250 kgf·cm, 18ft·lbf}
(c) Return the cap 19°.
|
(d) Using SST, turn the control valve shaft right and left 1 or 2 times. SST: 09616-00011 |
|
(e) Loosen the cap until the rack guide spring is not functioning.
|
(f) Using SST and a torque wrench, tighten the cap until the preload is within specification. SST: 09616-00011 Standard preload (turning): Center area 1.8 to 2.2 (18.4 to 22.4 kgf*cm, 16.0 to 19.5 in.*lbf) End area 1.3 to 1.7 (13.3 to 17.3 kgf*cm, 11.5 to 15.0 in.*lbf) |
|
|
11. INSTALL RACK GUIDE SPRING CAP LOCK NUT (a) Apply sealant to 2 or 3 threads of the nut. Sealant: Toyota Genuine Adhesive 1344, Three Bond 1344 or Equivalent (b) Holding the rack guide spring cap rotating, and using SST, torque the nut. SST: 09922-10010 Torque: 52 N·m {520 kgf·cm, 38ft·lbf} NOTICE: Use SST 09922-10010 in the direction shown in the illustration. HINT: Use a torque wrench with a fulcrum length of 345 mm (14.97 in.). (c) Recheck the total preload. Standard preload (turning): Center area 1.8 to 2.2 (18.4 to 22.4 kgf*cm, 16.0 to 19.5 in.*lbf) End area 1.3 to 1.7 (13.3 to 17.3 kgf*cm, 11.5 to 15.0 in.*lbf) (d) Remove the RH and LH rack ends. |
