7. Unscrew the lower arm mounting bolts and special bolt C, then remove the lower arm D.
Note: When reassembling, use new lower control arm mounting bolts and a new special bolt.
8. During installation, tighten the mounting bolts and special bolt to the recommended torque. Then install the vibration damper and install the mounting nut A to the recommended torque.
9. Perform the lower arm installation operations in the reverse order of the removal operations, observing the following.
When installing the steering knuckle, do not damage the ball joint protective boot.
Tighten all threaded connections to the recommended torque.
Before attaching the lower ball joint to the cam, remove any remaining grease from the threads and seating surface of the ball joint pin, from the surface of the cam bore, and from the threads and mating surface of the crown nuts.
First, assemble all components except the vibration damper and mount block and lightly tighten the bolts, then raise the suspension so that the weight of the vehicle rests on it before finally tightening the bolts to the recommended torque.
First tighten the castle nut to the lower torque limit, then tighten it only until the slot aligns with the hole in the ball stud. Do not loosen the nut to align the slot with the hole.
Before installing the wheel, clean the mating surface of the brake disc and the inner surface of the wheel disc hole.
10. Check the wheel alignment angles and adjust them if necessary.
11. For HID model: Perform the headlight position learning procedure.
Replacing bushings
1. Press out the lower arm A using a suitable socket wrench and hydraulic press and remove the lower arm from the bushing B.
Note: Apply protective tape to the lower arm under bushing C to prevent damage to the lower arm.
2. Wet the surface of the new bushing with water.
3. Align the angle of the lower arm A and the mount B of the bushing C. First press the bushing by hand.
Note: The installed bushing's mounting points point up and down relative to the installed lower control arm.
4. Press in the 32mm bushing using a socket wrench and hydraulic press.
5. Adjust the distance between the top of the lower arm and the surface of the bushing to the values shown.
Note: While applying pressure, hold the lower arm with a suitable flange bolt A.
