    Q:
    How do you remove the Trailing Arm for the 2011 GMC Terrain? Posted by Brooklynne T.
    A:
    To remove the trailing arm, follow similar steps. Loosen the rear wheel lug nuts, raise the rear of the vehicle on jackstands, and remove the rear wheel. Remove the three mounting bolts from the trailing arm-to-body bracket and unbolt the parking brake cable clip from the trailing arm. Then, remove the three bolts securing the arm to the knuckle and lift off the arm. If needed, remove the through bolt and separate the bracket from the trailing arm. For installation, reverse the removal steps, ensuring all mounting bolts are installed finger-tight before tightening them to the specified torque. Consider having the wheel alignment checked and adjusted. You can Select Your Vehicle to see complete installation and repair tips.
