Front lower arm

Repair Procedures

Removal and Installation

1. 1

   Remove the front wheel and tire (A).

   Tightening torque: 107.9–128 N·m

   

2. 2

   Remove the lower arm nut (A).

   Tightening torque: 58.8–71 N·m

   

3. 3

   Disconnect the front lower arm from the front steering knuckle using SST (09568-1S100).

   

4. 4

   Remove the lower arm (A) from the sub frame.

   Tightening torque:

   Bolt (B): 117.7–137 N·m lb·ft

   Bolt (C): 156.9–176 N·m lb·ft

   

5. 5

   Install in the reverse order of removal.

6. 6

   Check the wheel alignment.

   (Refer to Front Suspension System — "Front Wheel Alignment")

Disassembly

1. 1

   Disconnect the ball joint after loosening the nut (A).

   Tightening torque: 117.7–137 N·m

   

2. 2

   Install a new ball joint and tighten the nut (A).

   Tightening torque: 117.7–137 N·m

   

Inspection

1. 1

   Inspect the bushing for wear and damage.

2. 2

   Inspect the lower arm for bending or cracks.

3. 3

   Inspect the lower arm for deformation.

4. 4

   Check all bolts and nuts.

5. 5

   Check the ball joint rotating torque.

   If out of specification, replace the ball joint.

   Standard value: 9.8 - 29 N·m

   1. Move the ball stud (A) back and forth 5 times and rotate 5 times to evenly distribute the grease. Hold the ball stud in the center for 24 hours, then rotate it back and forth 3 times and rotate 3 times before measuring the torque.

      

   2. Read the constant torque value within 180° while rotating at approximately 12°/s.

      Standard value: 9.8 - 29 N·m

   3. Make sure the ball stud rotates smoothly.

6. 6

   Check the axial play of the ball stud (A). If there is any play, replace the ball joint (B).
