Q: How to Perform Maintenance on Rear Suspension Components and Trailing Arm?A: To maintain rear suspension, loosen rear wheel lug nuts, raise the vehicle, place it on jackstands, and remove the wheel. For the trailing arm, remove the bolt and nut, and the mounting bolts from the inner bushing. Check the bushing for wear and replace if needed. Tighten all fasteners and simulate normal ride height during installation. For the lower arm, remove the bolt and shock absorber-to-lower arm bolt, detach the inner pivot bolt and nut, and inspect the bushings. Install properly, ensuring tightening and simulating ride height. For the compensator arm, remove the bolt, then the nut and bolt. Check and replace bushings if needed, and install in reverse. For the upper arm, disconnect the brake components, remove the rear hub and bearing assembly, and detach the arms. Disconnect the parking brake cable bracket and remove the bushing shaft bolts. Inspect and replace the bushing as needed, and complete installation, raising the arm to simulate ride height and bleed the brake system.
