STEERING COLUMN: STEERING COLUMN ASSEMBLY: INSPECTION

NOTICE:
When using a vise, do not overtighten it.

1. INSPECT PRELOAD

(a) Secure the steering column assembly in a vice using aluminum plates and wooden block as shown in the illustration.

NOTICE:
* Do not overtighten the vice, as the steering column assembly may become deformed.
* Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.

(b) Install the 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 excess torque to the service nuts by using a tool such as an impact wrench.

HINT
These nuts are installed to turn the steering main shaft. They should be removed after inspecting the steering main shaft rotating torque.

(d) Using a torque wrench, turn the main shaft and measure the preload.





Preload:





If the preload is not as specified, replace the electric power steering column sub-assembly with a new one.

2. INSPECT STEERING LOCK OPERATION (w/o Smart Key System)

(a) Check that the steering lock mechanism is activated when the key is removed.





(b) Check that the steering lock mechanism is deactivated when the key is inserted and turned to the ACC position.

HINT
If there is any abnormality, replace the ignition switch lock cylinder assembly or steering column upper bracket assembly.

3. INSPECT STEERING COLUMN ASSEMBLY (for 2AR-FE)

(a) Check that the 2 capsules are securely installed to the steering column assembly as shown in the illustration.





Minimum Dimension:

If the preload is not as specified, replace the electric power steering column sub-assembly with a new one.

(b) Check the 2 capsules for deformation and damage.

If either of the capsules is deformed, loose, missing or damaged, replace the electric power steering column sub-assembly with a new one.
