Aircraft
The taxi was short and slow as we had a wheels up time about 10 minutes away. We did notice a clicking or very slight knocking at our feet when the aircraft was in motion. We discussed it and then dismissed it. We ruled out the tiller as it wasn't being used. I also noticed no pulling of the steering. Upon takeoff clearance; the steering immediately pulled to the right. I corrected back to the center line. At this point it felt like a strong crosswind with no correction. Wind was calm. After correcting; it pulled again hard to the right and I aborted the takeoff. I'd estimate the speed at around 40 kts. This was not a sudden jerk; but something that became more pronounced with speed. We exited the runway; then taxied to the de-ice pad to troubleshoot and call Maintenance control. At this point the pulling to the right was much more pronounced; even at low speeds. Also; the steering was disengaging on taxi. The passengers were notified and everyone remained comfortable. There were no complaints. Water service was performed by the FAs while in the de-ice pad. After communication with Maintenance Control; we taxied back to gate to await maintenance to arrive. Again; the threat was the steering issue and we contained it the best we could.
EMB-145 Captain reported rejecting the takeoff and returning to the gate for maintenance after experiencing nose wheel steering issues.
