Before to attempt to remove the upper control arm on 2010 and earlier models of the vehicle, the wheel lug nuts must be loosened, the vehicle must be lifted and securely placed on jackstands under the frame rails, and the wheel must be taken off. Then remove the inner fenderwell liner, and unscrew the nut on the upper balljoint stud, but do not remove it then use the ball joint removal tool to remove the ball joint from the steering knuckle. Following that, unscrew the control arm mounting bolts and take the upper arm out from its frame bushings. For the 2011 and later models make sure that the wheels are set to a straight position and then unbolt the shock upper mounting studs and if needed remove the harness clips. Disconnect the upper cowl cover and in case of replacing the left side upper control arm, remove the air filter housing and the intermediate shaft pinch bolt to provide the necessary access to the coupling. For the right side, undo the two nuts of the HVAC inlet duct to the firewall and pull out the duct. Take off the front wheels by first loosening front wheel lug nuts, then lifting the front part of the vehicle until it rests on jack stands. Remove electrical connectors that hinder the upper control arm removal, then undo the wheel speed sensor and the related clips and using a floor jack support the outer end of the lower control arm at normal riding position. Take out the lower shock mounting bolts, then loosen the upper balljoint nut and the on of the steering knuckle, then unbolt the balljoint and take out the nut. Remove the nuts from the upper control arm mounting and with the shock upper mounting nuts still on but loosened, releantly rotate the shock to allow the bolts to be removed the upper control arm. For installation reverse to the process of removal but tighten all bolts/nuts to the torque listed above, except the nuts on the pivot bolt until the car has normal ride height. If the wheel is on the nuts tighten the shock absorber as the outer end of the lower control arm with the help of the floor jack provide the standard height of the car. Then, the wheel is to be fitted and the corresponding lug nuts tightened with a certain degree of torque, afterwards the vehicle has to be lowered, checked for the level of lug nuts and, if the front end alignment is inaccurate, it has to be adjusted.
