To remove the control arm, loosen the front wheel lug nuts, raise the front of the vehicle, support it securely on jackstands and remove the wheel. On models where it would interfere, remove the under-vehicle splash shield. Remove the lock pin from the balljoint castle nut, then unscrew the nut a few turns (but don't remove it). Using a balljoint separator, separate the control arm balljoint from the steering knuckle. Remove the castle nut and control arm fasteners and remove the arm from the subframe. Inspect the front and rear bushings for cracks and tears, the balljoint for looseness, and the control arm for straightness. Installation is the reverse of removal, noting that the castle nut and control arm bolts must be replaced with new fasteners, the castle nut must be tightened to the torque, and the control arm pivot bolt and rear bushing bolts must be tightened to the torque. Install the wheel and lug nuts, lower the vehicle and tighten the lug nuts to the torque, and have the front wheel alignment checked and, if necessary, adjusted.
