To remove the control arm, first take out the outboard and inboard pivot bolts, then pull the inboard side of the arm down until it clears the body and slide it towards the center of the vehicle until it is free of the hub carrier. Check the bushings at each end of the control arm and the arm itself for any damage or wear. For installation, position the control arm and install the retaining bolts, tightening them to 60 ft. lbs. (83 Nm). For 1988-91 models, raise and safely support the vehicle, then remove the rear wheel and tire assembly. For all models except the Civic Wagon with 4WD, remove the brake drum or rotor, spindle nut, and hub unit, disconnect the parking brake cable and brake line from the wheel cylinder, and remove the brake backing plate. For the 4WD Civic Wagon, remove the brake drum and spindle nut, and disconnect the parking brake cable. Disconnect the brake hose from the brake line and plug it. Support the lower control arm or beam axle with a jack, then remove the trailing arm bushing mounting bolts and disconnect the upper arm and compensator arm from the trailing arm if equipped. For the Civic Wagon with 4WD, remove the rear half shaft outboard CV-joint from the trailing arm using a puller, then remove the trailing arm from the vehicle. Install the trailing arm in position and tighten all bolts and nuts with the vehicle on the ground to ensure proper tightening. Reinstall the half shaft outboard CV-joint if it was removed, reconnect the upper control arm and compensator arm if equipped, and install the trailing arm bushing bolts. Reconnect all hoses and cables to the trailing arm and the brake line, then install the backing plate and any brake components, torquing all bolts to specifications and bleeding the brake system. For the upper control arm, raise and safely support the vehicle, remove the rear wheel and tire assembly, and support the lower control arm or rear axle as necessary. On Accord and Prelude models, remove the cotter pin and castle nut from the upper ball joint, then separate the ball joint from the knuckle using a suitable tool. Remove the upper control arm mounting bolts and the upper control arm itself, then reinstall in reverse order, torquing the bolts with the vehicle on the ground to 29 ft. lbs. (40 Nm) for the control arm-to-body and 40 ft. lbs. (55 Nm) for the control arm-to-trailing arm. For the lower control arm, raise and safely support the vehicle, remove the rear wheel and tire assembly, and if necessary, remove the strut or radius rod mounting bolts from the lower control arm. On Prelude models, remove the cotter pin and castle nut from the ball joint, then separate the ball joint from the knuckle using a suitable tool. Remove the lower arm mounting bolts and the lower control arm, then reinstall in reverse order, tightening the bolts with the vehicle on the ground and torquing the lower control arm-to-body bolt to 40 ft. lbs. (55 Nm) and the control arm-to-trailing arm bolt to 29 ft. lbs. (40 Nm).
