7. Install the lower arm in the reverse order of removal paying particular attention to the following items:
^ Be careful not to damage the ball joint boot when connecting the lower arm to the knuckle.
^ Use a new self-locking cam nut and a new self-locking nut during reassembly.
^ First install all of the components, and lightly tighten the bolts and nuts, then raise the suspension to load it with the vehicle's weight before fully tightening it to the specified torque.
^ Tighten all mounting hardware to the specified torque values.
^ Before connecting the ball joint to the knuckle, degrease the threaded section and tapered portion of the ball joint pin, the connecting hole, the threaded section and matching surface of the castle nuts.
^ Tighten the castle nut to the lower torque value, then tighten only far enough to align the slot with the ball joint pin hole. Do not align by loosening the castle nut.
^ Reinstall the cotter pin on the castle nut after torquing.
^ Before installing the wheel, clean the mating surface of the brake disc and the inside of the wheel.
^ Check the wheel alignment, and adjust it if necessary.
