To remove the control arm for 2009 and earlier models, mark the relationship of the control arm to the subframe while the vehicle is at normal ride height. The front wheel is removed after loosening the wheel lug nuts and raising the front of the vehicle on jackstands. If available, unplug or pull out of place ABS wheel speed sensor and harness from its position within control arm. After that, separate balljoint from steering knuckle and remove some fasteners connecting control arm with this subframe. In order to verify if there are any distortions or worn out parts, inspect the control arm and bushings checking for any damage which should be replaced only if damaged.Since all bolts were tight when they got installed, loosen them first before removing them during installation until you get them in numbers that do not exceed fifteen per square inch; alternatively use a torque wrench set between twenty five foot-pounds (25 ft lbs) and forty-five ft-lbs.For removal with GNB front suspension models 2010 onwards one has to look at how they can release front wheels' nuts loosen jack up their cars using jacks stands take away tires from axles disconnect height sensor plus w/harness then follow it up by undoing rear bushing-to-subframe fasteners nut bolt yoke on strut as well pawl finally unscrewed under front bracket above whole assembly install reverse new bolts are used tighten as per instruction manual.In case of GNA front suspension models 2010 onwards, one has to look at how they can release front wheels' nuts loosen jack up their cars using jacks stands take away tires from axles detach flange connector in addition pinch-bolt that joins two in proximity strucker others back pads allowing connection between shock absorber shaft end ears mountings would still remain intact otherwise pressed down farther rearwardly just behind inside bore wall underneath rubber disc small metal part lining onto other side only through existing hole inside upper lip separate bushing located near large bottom surface is pushed outwards at same time lower one goes inwards similarly cm beside main body over which will be positioned adequate space between two components because it's here your tool needs to get locked up against case we're discussing about repair field technicians won't this without certain knowledge concerning difficulty involved.To remove the control arm, special tools are necessary and it is recommended for the control arm to be taken for bushing replacement.

Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands. Apply the parking brake and block the rear wheels to prevent rolling off the jackstands, then remove the wheel. If only one control arm is being removed, disconnect that end of the stabilizer bar; if both are being removed, disconnect both ends. Remove the balljoint stud's castellated nut and cotter pin, then separate the balljoint from the control arm using a separation tool or a large pry bar, taking care not to overextend the inner CV joint. Remove the two control arm pivot bolts and detach the control arm. Inspect the control arm bushings for hardening, excessive wear, and cracks; if they are worn or deteriorated, take the control arm to a dealer service department or repair shop for replacement. Position the control arm in the suspension support and install the pivot bolts without fully tightening them. Insert the balljoint stud into the control arm, install the castellated nut, and tighten it to the specified torque, adjusting if necessary to align the cotter pin hole, then install a new cotter pin. Use a floor jack under the balljoint to raise it to simulate normal ride height and tighten the control arm pivot bolts to the specified torque. Install the stabilizer bar-to-control arm bolt, spacer, bushings, and washers, tightening the nut to the specified torque. Finally, install the wheel, lower the vehicle, and tighten the lug nuts to the specified torque, then drive to a dealer service department or alignment shop for a front wheel alignment check and adjustment if needed.

Next, remove the stabilizer bar link from the control arm and either remove the steering knuckle or separate the balljoint from the steering knuckle.

Loosen the wheel lug nuts, apply the parking brake, and raise the front of the vehicle. Support it securely on jackstands and remove the wheel.
