4. 4
   Remove the driveshaft nut (A) from the front hub while applying the brake.

   Tightening torque: 215.7 ~ 255 N·m (22.0 ~ 26.0 kgf·m, 159.1 ~ 188.0 lbf·ft)

   

5. 5
   Disconnect the tie rod end ball joint (A) from the steering knuckle.

   1. Remove the cotter pin (C).
   2. Remove the castellated nut (B).

      Tightening torque: 34.3 to 44 N·m

      

6. 6
   Loosen the mounting bolt and remove the wheel speed sensor (A) from the steering knuckle.

   Tightening torque: 6.8 - 10.7 N·m

   

7. 7
   Loosen the bolt and nut, then remove the steering knuckle from the strut assembly (A).

   Tightening torque: 156.9 ~ 176 N·m (16.0 ~ 18.0 kgf·m, 115.7 ~ 130.2 ft-lbf)

   

8. 8
   Disconnect the drive shaft (A) from the front hub assembly.

   

9. 9
   Loosen the bolt and nut, and remove the lower arm (A).

   Tightening torque: 98.0 ~ 118 N·m

   

10. 10
    Remove the front lower arm from the front steering knuckle using SST (0K545-A9100).

    1. After removing the bolts from the front steering knuckle, install and tighten the body support bolt (A).

       

    2. Insert the auxiliary body (A) between the front steering knuckle and the auxiliary body bolt.
