When removing control arm-turn the lug nuts on the side of the car you are removing the arm from loose and apply the parking brake-lift the front of the vehicle, and place it securely on jack stands-then remove the wheel. On those built after December 2004 the nut and bolt that link the stabiliser bar to the strut should be removed so that the latter can be rotated to reveal the control arm bolts. After that, unlock a lock pin of a castle nut between the lower control arm and the
Steering Knuckle, loosen the nut but do not take it off, and using a hammer, define the boss on the steering knuckle from the lower ball joint stud. Do not hit the lower control arm bushing or the balljoint grease plug location; also do not exert force to split the inner CV joint or try to pry loose the lower balljoint from the steering knuckle. Pull the balljoint stud and set the instrument back, then detach the castle nut and split the balljoint from the steering knuckle. Then unbolt the two bolts which hold the control arm to the subframe and pull out the control arm. In inspection, the control arm should be as straight as possible and if not, it should not be bent into the right position but replaces immediately. Inspect the bushings for signs of cracks, tears or wears, If there is, replace the control arm with new one. For installation, reverse the removal steps, the balljoint stud castle nut requires tightening to the lower torque figure and in case it is loosened for alignment of the slots in the nut to the hole in the stud use new fasteners as recommended. Insert a new lock pin, lift the outer end of the control arm using a floor jack and then tighten the control arm to subframe bolts to the recommended torque. Last but not the least, fix the wheel back and the lug nuts, then lower the vehicle, finally, using a torque wrench tighten the lug nuts to the factory recommended set torque and even align the front wheel if needed.
