Narrative:
I was the first officer on flight to ZZZ. Everything was normal through touchdown. As the nosewheel was lowered, a popping or snapping sound was heard. I thought it was just the normal noisy nose strut or the nosewheel hitting a crack in the runway. The spoilers deployed normally and reverse thrust was applied. The aircraft started to drift right of centerline. I was aware the captain was having to use more than usual left rudder to keep the aircraft moving back to center, but we did continue going straight. As the airspeed decreased, drift started again to the right. By now, full left rudder and full left reverser were applied. The captain stated 'I can't stop it.' I came on the brakes, heavier on the left brake, but the drift continued until departing the runway at approximately 30 KTS. Nosewheel and right main in the grass. No injuries to passenger or crew. Inspection of the nose gear revealed a broken steering cable and bird remains.

Title: A B737-300 AFTER LNDG ROLLOUT THE AIRPLANE DISPLAYED STEERING DIFFICULTY AND DEPARTED THE RWY AT 30 KTS. FOUND BROKEN STEERING CABLE AND BIRD REMAINS.
Narrative: I WAS THE FO ON FLT TO ZZZ. EVERYTHING WAS NORMAL THROUGH TOUCHDOWN. AS THE NOSEWHEEL WAS LOWERED, A POPPING OR SNAPPING SOUND WAS HEARD. I THOUGHT IT WAS JUST THE NORMAL NOISY NOSE STRUT OR THE NOSEWHEEL HITTING A CRACK IN THE RWY. THE SPOILERS DEPLOYED NORMALLY AND REVERSE THRUST WAS APPLIED. THE ACFT STARTED TO DRIFT R OF CTRLINE. I WAS AWARE THE CAPT WAS HAVING TO USE MORE THAN USUAL L RUDDER TO KEEP THE ACFT MOVING BACK TO CTR, BUT WE DID CONTINUE GOING STRAIGHT. AS THE AIRSPD DECREASED, DRIFT STARTED AGAIN TO THE R. BY NOW, FULL L RUDDER AND FULL L REVERSER WERE APPLIED. THE CAPT STATED 'I CAN'T STOP IT.' I CAME ON THE BRAKES, HEAVIER ON THE L BRAKE, BUT THE DRIFT CONTINUED UNTIL DEPARTING THE RWY AT APPROX 30 KTS. NOSEWHEEL AND R MAIN IN THE GRASS. NO INJURIES TO PAX OR CREW. INSPECTION OF THE NOSE GEAR REVEALED A BROKEN STEERING CABLE AND BIRD REMAINS.
