How do I remove and replace the control arm?

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.
