Narrative:

While taxiing slow and straight on taxiway F the aircraft shuddered and pulled to the left. I stopped immediately. It had felt like we had taxied on a very rough surface. I thought we had either blown a tire or had a problem with the brakes or landing gear. We had no unusual indications in the cockpit. I made an announcement to the passengers and flight attendant to stay seated and that we were having maintenance personnel coming out to inspect our gear. After talking with maintenance I attempted to taxi again and the aircraft pulled left with no nose wheel steering. We suspected the torque links had become disconnected. When the tow team came out they reconnected to torque links and I taxied back to the gate for a maintenance inspection. The nose gear and tires were found to be normal and we continued our flight. Torque links may have been connected improperly. This could have resulted in taxiway or runway excursion or a problem with the gear if we departed.
