  To remove the trailing arm, start by removing the control link and undo the retaining screws or fasteners to remove the protective cover from the front of the trailing arm. Loosen the retaining nut or bolts of the handbrake cable from the brake caliper, then remove the cable from the trailing arm. Next, take off brake disc and disconnect the abs wheel sensor wiring connector, unclip the wiring so that to remove the wheel sensor with the trailing arm, if the new one with the new trailing arm, remove the sensor completely. If replacing the trailing arm, remove the hub assembly by loosening and removing the retaining bolts then remove the brake backplate and caliper mounting bracket from the arm. Support the lower arm and loosen and remove the nuts and pivot bolts holding the upper link and lower arm to the trailing arm.

Insert the pivot bolts for the upper link and lower arm on the trailing arm and fit new nuts and tighten lightly. If the case, reattach the brake caliper mounting bracket and backplate to the trailing arm, and tighten the retaining bolts to the recommended torque before refitting the hub assembly.
