lb·ft)
Bolt (C) : 156.9 - 176.5 N·m (16.0 - 18.0 kgf·m, 115.7 - 130.2
lb·ft)
|

|
| 5. |
Install in the reverse order of removal.
|
| 6. |
Check the wheel alignment.

Move the ball stud (A) 5 times to the front and back, and rotate
5 times to evenly apply the grease. Fix the ball stud stationary
for 24 hours at the center, then roll 3 times to the front and back,
and rotate 3 times before measuring the torque.

|
| (2) |
Read the constant torque value within 180° when it is rotated
at speed of approximately 12°/s.
|
Standard value : 9.8 - 29.4 N·m (1.0 - 3.0 kgf·m, 7.2
- 21.7 lb-ft)
