7. Remove the flange bolt (A) from the vehicle, and remove the upper arm (B).
NOTE: Use new flange bolt during reassembly.
8. Install the upper arm in the reverse order of removal, and note these items:
^ Be careful not to damage the ball joint boot when connecting the upper arm to the knuckle.
^ Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the connecting hole, and the threaded section and mating surface of the castle nut.
^ First install all the components and lightly tighten the flange bolt and the castle nut, then raise the suspension to load it with the vehicle's weight before fully tightening to the specified torque values.
^ Torque the castle nut to the lower torque specification, 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.
^ Refer to the stroke and stroke/headlight leveling sensor replacement to install the stroke sensor to the upper arm.
^ Before installing the wheel, clean the mating surface of the brake disc/drum and the inside of the wheel.
^ Check the rear wheel alignment, and adjust if necessary.
