7. Tighten the upper arm mounting bolts to the specified torque value.
8. Remove the rod.
9. Install the remaining parts in the reverse order of removal, and note these items:
   • 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. Do not place the jack against the ball joint pin of the knuckle.
   • Be careful not to damage the ball joint boot when connecting the knuckle.
   • Torque the castle nut to the lower torque specification, then tighten it only far enough to align the slot with the ball joint pin hole. Do not align the castle nut by loosening it.
   • Before installing the wheel, clean the mating surfaces on the brake disc and the inside of the wheel.
   • Check the wheel alignment, and adjust if necessary (see WHEEL ALIGNMENT ).
