Toyota 48068-04030 Control Arm

Loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands while applying the parking brake before removing the wheel. For 2WD models (except PreRunner), remove the stabilizer bar link from the lower control arm. Unbolt the shock absorber/coil spring assembly from the lower control arm and remove the bracket mounting bolts that hold the control arm to the steering knuckle at the balljoint. Make alignment marks on both sides of the front and rear pivot fasteners where the cam adjusters meet the frame, ensuring they are marked distinctly to avoid confusion, then remove the pivot bolts and detach the control arm from the frame. Inspect the bushings for wear and deterioration; if they are cracked or damaged, take the arm to an automotive machine shop for new bushings. If replacing the lower control arm, separate the bracket from the balljoint after removing the control arm by securing the arm, removing the cotter pin from the ballstud, loosening the lower balljoint nut about 1/4 inch, and using a two-jaw puller or balljoint separator to detach the balljoint from the bracket. Installation is the reverse of removal, ensuring that the alignment marks are lined up and all suspension fasteners are tightened to the specified torque values, using a new cotter pin and castle nut on the lower control arm balljoint, and adjusting the castle nut as needed to align the hole in the ballstud with the slots in the nut without loosening it. The pivot bolts should be tightened with the vehicle at normal ride height, which can be achieved after assembly by lowering the vehicle to the ground and bouncing it a few times or by raising the lower control arm with a floor jack. Finally, tighten the lug nuts to the specified torque and have the wheel alignment checked and adjusted if necessary.
