Narrative:
The aircraft was pushed off the gate and the tug was positioned was approx 90 degrees to the nose when push bar was detached. The wing walker attempted to reinstall the torque link but was having trouble so the tug driver jumped off and installed the pins. We got the standard wave off and then proceed to taxi when the nose wheel started to shimmy and banging noises were coming from the nose wheel area. The captain stopped the taxi and I called ground control to inform them we had a nose wheel issue. As a safety precaution ground control called to have the fire truck standing by. After ground operation inspected the nose wheel it was determined the torque link had separated. We were then towed back to the gate where maintenance control inspect to aircraft. During push back the aircraft was at a 90 deg angle to the tug when the tow bar was detached. I have seen many time when they push an aircraft backwards at these types of angles they always pull forward and straighten out the nose prior to installing the torque link pins. This may have been the reason the torque pin did not install properly.
