Front Upper Arm
FRONT UPPER ARMINSPECTION
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. Move the stabilizer link ball joint stud in a circular motion 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 kgf-cm, 0.37-1.11 ft. lbs.)
NOTE: Measure at the range of 0.5-2 rpm after moving 3° at room temperature.
4. If the rotating torque exceeds the upper limit of standard value, replace the upper arm assembly.
5. If the rotating torque is below the lower limit of the standard value, and it doesn't have any drag and excessive play, the ball joint may be reused.
