Loosen the wheel lug nuts, raise the vehicle, and support it securely on jack stands while blocking the front wheels to prevent rolling, then remove the wheel. Support the lower control arm with a floor jack and remove the rear brake hose bracket bolt from the upper control arm along with the upper control arm-to-knuckle mounting bolt/nut. Next, remove the upper control arm bushing bolt and the upper control arm-to-subframe nut and bolt. Installation is the reverse of removal, ensuring to tighten the fasteners to the specified torque while raising the lower control arm to simulate normal ride height. Disconnect the electronic ride control rear suspension position sensor link from the control arm if equipped, mark the inner pivot bolt cam washer-to-subframe relationship for reinstallation, and remove the shock absorber-to-lower control arm nut/bolt. Detach the stabilizer bar link from the control arm, remove the control arm-to-subframe nut/bolt, and detach the arm from the vehicle. For the trailing arm, support the lower control arm with a floor jack, remove the trailing arm-to-knuckle nut/bolt, and the trailing arm-to-subframe bolt before removing the arm. Installation follows the reverse order with fasteners tightened to the specified torque, again raising the lower control arm to simulate normal ride height. For the toe-link, unclip the wheel speed sensor harness from the arm, mark the toe link inner bolt adjuster cam to the subframe, and remove the inner toe link nut/bolt along with the outer toe-link bolt before removing the link arm. Reinstallation is the reverse of removal, ensuring to tighten the fasteners to the specified torque while aligning the match marks on the inner pivot bolt adjuster cam and subframe, and raising the lower control arm to simulate normal ride height. Finally, have the wheel alignment checked and adjusted if necessary.

To remove the front control arm, first remove the front control arm-to-subframe pivot bolt and nut, then loosen the lower ball joint nut. Use a ball joint removal tool to separate the ball stud from the knuckle, ensuring the ball stud does not turn with the nut by holding it with a wrench. After that, remove the front lower control arm.
