Narrative:

3rd leg of the day. Pros sys 2 deferred per release but had not caused any problems on the 2 prior flights. First officer (first officer) was PF (pilot flying). ACARS was problematic over the day; with times not sent and performance data obtained over the phone. All other activities were uneventful. After a normal takeoff roll the landing gear was retracted on schedule and significant mechanical noise; kicks in the rudder pedals; a master warning and flickering gear position icons displayed. Being familiar with the QRH procedure; I had it during recurrent training; and due to the substantial mechanical noises from the nose gear I immediately lowered the landing gear lever again and notified ZZZ tower we needed to remain in the airport vicinity. 200 KIAS was set and once we were happy with the aircraft state; especially hydraulics; the QRH was actioned.my decision to return to ZZZ was made because of the lack of ACARS communication; therefore an unknown performance state for continued gear down flight combined with the mechanical noise from the gear retraction mechanism. I elected to return to a long runway in daylight conditions. The fas (flight attendants) were advised using the emergency function of the intercom; briefed and cabin prepared. Passengers were advised and 30 minutes after takeoff an uneventful landing was made with [emergency services] in attendance. Aircraft was taxied back to the gate; deplaned and handed over to mx after debriefing with the duty cp (chief pilot); [operations control]; and mx. No suggestions really; fas did a great job; ATC was excellent. Having speed cards out for takeoff was very helpful. An inoperative ACARS made my decision easier; but I doubt the outcome would have been different. Choosing to land in daylight with suspected mechanical damage was clearly preferable to continued further flight and consistent with the QRH direction to land at the nearest suitable airport.
