1. Remove the flange bolt (A), and remove the upper arm (B).

1. Install the upper arm in the reverse order of removal, and note these items:
   - Be careful not to damage the ball joint boot when installing the knuckle.
   - Tighten all mounting hardware to the specified torque values.
   - First install all the components and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
   - Tighten the castle nut to the lower torque value, then tighten it only far enough to align the slot with the hole in the stud. Do not align the castle nut by loosening it.
   - Before installing the wheel, clean the mating surface on the brake disc and inside of the wheel.
   - Check the wheel alignment, and adjust it if necessary.
