UPPER ARM





COMPONENTS

REMOVAL
1. Remove the wheel and tire.
2. Loosen the ball joint nut, but do not remove it.





3. Using the special tools (09568-34000), disconnect the upper arm ball joint from the knuckle.





4. Remove 2 nuts on the wheel house panel and remove the upper arm assembly.





5. Remove the upper arm shaft.





6. Installation is the reverse of removal.

INSPECTION
1. Check the bushing for wear and deterioration.
2. Check the upper arm for bending or breakage.
3. Check the ball joint for rotating torque.
1) If there is a crack in the dust cover, replace it and add grease.
2) Shake the stabilizer link ball joint stud several times.





3) Mount the self-locking nut on the ball joint, and then measure the ball joint rotating torque.
Standard value: 1.5 - 2.5 Nm (15 - 25 kg-cm, 1.1 - 1.8 ft. lbs.)

NOTE: Measure at the range of 0.5 - 2rpm after vibrating 3° at room temperature after approximately 24 hours from assembly.

4) If the rotating torque exceeds the upper limit of standard value, replace the upper arm assembly.
5) Even if the rotating toque is below the lower limit of the standard value, the ball joint may be reused unless it has drag and excessive play.
