Front Lower Arm: Inspection

WARNING: This page is about a different car, the 2007 Kia Sedona and 2006 Kia Sedona. However, it is still accessible from the selected car via links, so may be relevant.

Check the bushing for wear and deterioration.
Check the lower arm for bending or breakage.
Check the ball joint dust cover for cracks.
Check all bolts.
Check the lower arm ball joint for rotating torque.
1. If a crack is noted in the dust cover, replace the ball joint assembly.
2. Move the ball joint stud several times in a circular motion.
3. Measure the ball joint rotating torque.
  Standard value:
  
  1-3.5 N.m (10-35 kgf.cm, 0.72-2.53 lb-ft)
  
  NOTE: Measure torque using the special tool (09532-11600) and torque wrench at the range of 0.5 - 2 RPM after moving the ball joint stud 10 times at room temperature.

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