Chevrolet Full-size Cars 1968-1978 Repair Guide

Rear Upper Control Arm



Remove and install ONLY one upper control arm at a time. If both arms are removed at the same time, the axle could roll or slip sideways, making installation of the arms very difficult.

  1. Raise and support the rear of the vehicle on jackstands under the axle. Support the nose of the axle with a jackstand.
  3. Remove the upper control arm nut at the axle.

To remove the mounting bolt from the axle, it may be necessary to rock the axle. On some vehicles, it may be necessary to remove the lower shock absorber stud to provide clearance for the upper control arm removal.

  1. Remove the upper control arm-to-frame nut and bolt, then the control arm.
  3. To install, reverse the removal procedures. Torque the upper control arm-to-axle nut to 70 ft. lbs., the upper control arm-to-axle bolt to 79 ft. lbs. and the upper control arm-to-frame bolt to 70 ft. lbs.
