Chevrolet 13319412 Axle Beam

To remove the rear axle assembly, start by loosening the rear wheel lug nuts and blocking the front wheels to prevent the vehicle from rolling. Then, raise the rear of the vehicle and support it securely on jackstands before removing the rear wheels. Disconnect the brake pipes from the hoses at the trailing arms and plug the fittings to prevent dirt or fluid loss. Disconnect the ABS electrical connectors at the rear axle and release the ends of the parking brake cables from the rear brakes, freeing them from any brackets on the rear axle. Remove the coil springs and the outer ends of the Watts links, if equipped. Support the rear axle with floor jacks and remove the mounting bolts securing the axle bushing brackets to the body on each side. Carefully lower the rear axle assembly to the floor and inspect the trailing arm pivot bushings for deterioration. If replacement is needed, take the axle assembly to a shop for bushing replacement. To install the rear axle assembly, follow the reverse steps of removal, ensuring to raise the axle assembly to approximate ride height before tightening the through-bolts. Align the axle bushing brackets to the body on each side and tighten the bolts to the proper torque specifications. Bleed the brake system, tighten the wheel lug nuts, and have the rear wheel alignment checked and adjusted if necessary.
