Upper Arm






Components

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 0.5 - 1.5 Nm (5 - 15 kg-cm, 4.43 - 13.27 inch)





NOTE: Measure at the range of 0.5 - 2 rpm after vibrating 3° at room temperature after approx. 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.
