Q: How do you remove the lower Control Arm on Chevrolet C1500 and K1500?
A: For the removal of the control arm on 2WD models, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel, followed by the coil spring and lower balljoint. Take the control arm to a dealer or shop for any necessary replacements. To install, reverse the removal steps, ensuring the pivot bolts are installed from the front. Tighten all nuts to specified torque and lubricate the new balljoint. For the removal of the control arm on 4WD models, begin by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the wheel and front splash shield for access. Remove the Shock Absorber, inner tie-rod end, and driveaxle. Loosen the torsion bar adjusting bolt and support the lower control arm with a floor jack. Disconnect the steering knuckle from the lower balljoint and lift the assembly up, supporting it with a block of wood. Slowly lower the jack to release tension on the torsion bar. Slide the torsion bar forward and remove the lower control arm and torsion bar as a unit. Check the bushings for damage and replace if necessary. To install, insert the torsion bar into the lower control arm and raise the arm into position, inserting the rear end of the bar into the crossmember. Position the lower control arm in the frame brackets and install the control arm pivot bolts, washers, and nuts. Slide the torsion bar back into the adjusting arm. Raise the lower control arm with the floor jack and insert the balljoint stud into the steering knuckle. Install the balljoint stud nut and tighten. Install the driveaxle, connect the inner tie-rod to the relay rod, and install the shock absorber. Connect the stabilizer bar and install the wheel. Lower the vehicle and tighten the lug nuts. Install the splash shield and measure the vehicle's ride height to ensure it sits level.
Q: How do you remove the upper Control Arm on Chevrolet C1500 and K1500?
A: This procedure applies to both 2WD and 4WD models. To remove the upper control arm, start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Place 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 and disconnect the brake hose bracket from the upper control arm. If the vehicle has an alignment kit, mark the positions of the adjuster cams before removing the upper control arm pivot bolts and nuts. Inspect the pivot bolt bushings and replace if necessary. To install the upper control arm, position it in the frame brackets and tighten the bolts and nuts. Attach the balljoint to the steering knuckle and connect the brake hose bracket to the upper control arm. Install the wheel and lower the vehicle. Finally, reinstall the air cleaner extension if it was removed.
