GM 22689676
Upper Control Arm, Rear

A mechanic must first lift and support the vehicle before replacing its Trailing Arm. Start by removing the Trailing Arm bracket bolts from the body then continue with the Trailing Arm Bushing bolts from the bracket. Disassembly begins with unfastening the Trailing Arm bolts attaching to the knuckle then proceeding to free the park brake cable clip and Trailing Arm. First install the Trailing Arm onto the knuckle before tightening all bolts to 110 nm (81 ft. Lbs.). Loosely mount the Trailing Arm Bushing to bracket nut and bolt after placing the bracket to the Trailing Arm. Push the Trailing Arm upward while installing the front bolt with loose tension but complete alignment with a drift on the other bolts. Tighten the Trailing Arm bracket to body bolts to 110 nm (81 ft. Lbs.) secure the Trailing Arm Bushing to bracket nut and bolt by applying 160 nm (118 ft. Lbs.) torque. Finally, install the park brake cable clip and tighten the bolt to 25 nm (18 ft. Lbs.) before lowering the vehicle.
