7. Install the upper arm in the reverse order of removal, and note these items
   • First install all of the components, and lightly tighten the bolts and the nuts, then raise the suspension to load it with the vehicle's weight before fully tightening it 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
   • Before connecting the ball joint, degrease the threaded section and the tapered portion of the ball joint pin, the ball joint connecting hole, the threaded section, and the mating surfaces of the castle nut
   • 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 of the brake disc and the inside of the wheel
8. Check the wheel alignment, and adjust it if necessary (see WHEEL ALIGNMENT )
