PROCEDURE
1. INSPECT PRELOAD
(a) Secure the steering column assembly in a vise using aluminum plates, cloths and wooden blocks. NOTICE:
|
|
(b) Install 2 service nuts to the steering main shaft. Recommended Service Nut: Thread Diameter 12.0 mm (0.472 in.) Thread Pitch 1.25 mm (0.0492 in.) | |
(c) Simultaneously rotate the service nut that was installed first counterclockwise and rotate the service nut that was installed second clockwise to lock them.
NOTICE:
Do not apply excessive torque to the service nuts by using a tool such as an impact wrench.
HINT:
The service nuts are used for turning the steering main shaft during inspection of the steering main shaft rotating torque.
Remove the service nuts after performing this inspection.
(d) Using a torque wrench, turn the steering main shaft at a constant rate of approximately 1 revolution every 4 seconds and measure the preload. Preload: 1.3 to 2.7 N*m (13.3 to 27.5 kgf*cm, 11.6 to 23.8 in.*lbf) If the preload is not as specified, replace the power steering ECU assembly or electric power steering column sub-assembly with a new one. | |
(e) Remove the 2 service nuts.
2. INSPECT STEERING COLUMN ASSEMBLY
(a) Check that the 2 bushings are securely installed to the steering column assembly. If the bushings are deformed, missing or damaged, replace the electric power steering column sub-assembly with a new one. | |
