1. Remove the front wheel.
2. Remove the flange bolt and flange nuts from the lower arm (A).

NOTE: During installation, install a new flange bolt and new flange nuts. After lightly tightening all three fasteners, tighten them to the specified torque in the following order; the nut on the front (B), the nut on the rear (C), then the bolt (D).





3. Disconnect the lower ball joint (E) from the lower arm.
4. Remove the spindle nut, and remove the outboard joint (A) from the knuckle (B) by tapping the driveshaft end (C) with a plastic hammer while drawing the hub outward.

8. Install the lower ball joint in the reverse order of removal, and note these items:
^ First install all the components, and lightly tighten the bolts and nuts, then tighten the lower ball joint to the lower arm to the specified torque. Raise the suspension to load it with the vehicle's weight before fully tightening the lower ball joint to the knuckle to the specified torque values.
^ Tighten all mounting hardware to the specified torque values.
^ Use a new spindle nut during reassembly.
^ Before installing the wheel, clean the mating surface of the brake disc and inside of the wheel.
