Q: How do you remove the lower control arm on Chevrolet Blazer,S10,GMC Jimmy and Sonoma?
A: Start by loosening the wheel lug nuts and raising the vehicle on jackstands to remove the control arm on a 2WD model. Remove the wheel, and then coil spring. To a dealer or shop equipped with all needed tools, take your control arm for replacement of any balljoint and bushings if necessary. When installing the control arm, follow reversal of removal steps noting that once the vehicle is at normal ride height, every fastener should be tightened to correct torque specs. The other method starts by loosening the wheel lug nuts and raising the vehicle on jackstands. After removing the wheel, front splash shield might be required in some cases. Disconnect both Shock Absorber and stabilizer bar from lower control arm. Finally detach lower balljoint from Steering Knuckle to remove Torsion Bar followed by lower control arm itself. Replacing control arm may depend on inspections made on its bushings which should appear either worn out or damaged. Raise it into position after positioning it correctly as you insert washers alongside pivot bolts of control arm without tightening them completely yet. When inserting cotter pin through lower nut's hole put floor jack up until Ball Joint stud can be seen inside steering knuckle hole and then tighten ball joint stud nut properly using correct torque wrench value set. Connect stabilizer bar; mount shock absorber;install torsion bar; do not forget about connecting stabilizer bar again; install cover over this part too, if needed.The last phase involves installation of wheels plus lug bolts and lowering vehicles as well before final tightening of lugs according to specified levels of torque.Tighten rearward pivot bolt types for correlation between current spindle angle readings as well as their prespecified torques when shield becomes applicable.Correct vehicle's levels at lateral points followed by regulating torsion bar until equal elevation attained largely across its body frame sections otherwise referred as maintaining levelness in such cases.
A: To remove the upper control arm, start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Support the vehicle securely and remove the wheel. Position a floor jack with a wood block under the lower control arm to relieve spring pressure on the upper control arm. Remove the air cleaner extension if necessary, and disconnect the brake hose bracket and ABS wheel speed sensor from the upper control arm. Disconnect the upper balljoint from the Steering Knuckle. On 2WD models, remove the pivot shaft nuts, bolts, and shims, noting their location. On 4WD models, mark the positions of the adjuster cams to the frame. Remove the upper control arm pivot bolts and nuts, and inspect the pivot bolt bushings for wear. Replace if necessary. To install the upper control arm, position it in the frame brackets and install the bolts and nuts, ensuring they are facing each other. Do not tighten completely. Attach the balljoint to the steering knuckle and connect the brake hose bracket. Install the wheel and lower the vehicle. Tighten the lug nuts and pivot bolt nuts to the proper specifications. Finally, install the air cleaner extension if it was removed.
