   *a	Service Nut

2. Simultaneously rotate the service nut that was installed first counterclockwise and rotate the service nut that was installed second clockwise to lock them.
   NOTE:

   Do not apply excessive 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.

3. Install a new O-ring to the power steering ECU with motor assembly.

   NOTE:

   First wipe off the existing grease from the splines, and then apply the dedicated grease supplied with a new power steering motor assembly or electric power steering column sub-assembly.

5. Insert the power steering ECU with motor assembly into the splines of the electric power steering column sub-assembly.
   NOTE:

   Do not damage the gears.

6. Secure the steering column assembly in a vise using aluminum plates and wooden blocks as shown in the illustration.
   NOTE:

   • Do not overtighten the vise, as the steering column assembly may become deformed.
   • Secure the steering column assembly so that the power steering motor assembly is directly upright.
   • Support the steering column assembly with a wooden block or similar item to ensure that it does not fall.
