Start the Trailing Arm replacement process by lifting the vehicle before you secure it in position. The first step involves removing anchor bolts which hold the park brake cable from both the Trailing Arm and the frame. Begin by removing the three Trailing Arm bracket to body bolts as well as the Trailing Arm Bushing to bracket nut and bolt and Trailing Arm to knuckle bolts before extracting the Trailing Arm piece. Following installation you must fit the Trailing Arm to both its knuckle bolts and apply a torque of 110 n.m (81 lb ft). Begin by aligning the Trailing Arm bracket to its position on the Trailing Arm. Then add the Trailing Arm Bushing to bracket nut and bolt before shifting the Trailing Arm upward to loosely install the front bolt. Position the drift to align the Trailing Arm bracket with the body bolts while tightening torque reaches 110 n.m (81 lb ft). Then tighten the Trailing Arm Bushing to bracket nut and bolt up to 160 n.m (118 lb ft). The process begins by installing the park brake cable routing bolt to the frame and tightening it to 12 n.m (106 lb in). Then route and tighten the bolt at the Trailing Arm up to 12 n.m (106 lb in), and finally lower the vehicle.

Raise and support the vehicle.

Install the park brake cable bolt to the trailing arm and the frame, reinstall the tire and wheel, and lower the vehicle.
